These Treats Disappear Faster Than Candy!

Halloween is my absolute favorite holiday, and crafting these Halloween Rice Krispies Treats has become my most cherished project yet! They are the epitome of festive, wonderfully simple to create, and consistently vanish from the dessert table in record time, delighting both children and adults alike. There’s something truly magical about seeing everyone’s faces light up when they spot these cute and spooky creations.

A few years back, I introduced my popular Pumpkin & Frankenstein Rice Krispie Treats, which quickly became a smashing success. That inspired me to expand the collection, bringing you even more creative ideas. This year, I’ve outdone myself with **eight brand-new, captivating designs**: the mysterious mummy, friendly ghost, charming black cat, creepy-crawly spider, soaring bat, goofy zombie, enchanting witch, and delicate spider web. Each one offers a unique touch to your Halloween spread!

These homemade treats are not just desserts; they’re an experience. They are absolutely perfect for any Halloween party, offering a fantastic opportunity for fun decoration sessions with family and friends. And honestly, they’re even more enjoyable to eat! My kids devoured them, and I’ll admit, I couldn’t resist sneaking a few (or more!) myself. Prepare for smiles, sticky fingers, and pure Halloween joy with every bite.

Quick Tip for Customizing Your Halloween Rice Krispie Treats

Each of these Halloween Rice Krispie Treat “recipes” is incredibly versatile and can be easily scaled up or down depending on the size of your gathering. When it comes to chocolate and candy melts, remember that the exact amount required will vary based on the size of your Rice Krispie Treat base and how thick you prefer your coating. It’s always a good idea to have a little extra chocolate or candy melts on hand – just in case you need to fix a mistake or want to add more decorative flair!

Crafting the Perfect Rice Krispies Treats Base from Scratch

The foundation of any great decorated Rice Krispies Treat is, of course, a perfectly soft, chewy, and delicious base. While many store-bought options exist, making them from scratch ensures the freshest taste and ideal texture for decorating. For my go-to recipe that guarantees success every time, click here for my favorite Rice Krispies Treats recipe. When preparing your base for these Halloween designs, simply omit any white chocolate coating or sprinkle toppings mentioned in the original recipe. Instead, you’ll use the fun and spooky decorations outlined in the specific design instructions below.

Want to add an extra layer of flavor to your Halloween creations? Consider trying one of these exciting flavor variations for your Rice Krispies Treat base, perfect for elevating your spooky snacks:

  • Peanut Butter Rice Krispie Treats: A rich, nutty base that pairs wonderfully with chocolate decorations.
  • Scotcheroos: For those who love a butterscotch and chocolate combination – a unique twist for your Halloween treats.
  • Chocolate Rice Krispie Treats: A cocoa-infused base that makes for an even darker, spookier foundation for designs like bats or black cats.
  • Fruity Pebble Rice Krispie Treats: Add a burst of vibrant color and fruity flavor for a playful, less traditional Halloween treat, perhaps for a monster theme!

Expert Tips for Perfect Halloween Rice Krispies Treats Every Time

Achieving that ideal soft and chewy texture for your Rice Krispies Treats is crucial, especially when you plan to decorate them. Here are some essential tricks and tips to ensure your homemade Halloween Rice Krispie Treats are nothing short of perfection:

  • Keep the Heat Low and Slow: Patience is a virtue when melting marshmallows. Always use low to medium-low heat and stir constantly. High heat can cause the marshmallows to caramelize too quickly, resulting in a hardened, brittle texture once cooled. Slow melting ensures a smooth, pliable mixture.
  • Always Use Fresh Marshmallows: This tip is a game-changer! Fresh marshmallows melt far more smoothly and evenly, leading to softer, more consistent bars. Stale marshmallows can be grainy or resist melting completely, affecting the final texture of your treats.
  • Don’t Pack Too Tight: Once you’ve combined your cereal and melted marshmallows, it’s tempting to press the mixture firmly into the pan. Resist this urge! Gently press the mixture into your prepared pan using lightly greased hands or a piece of parchment paper. Applying too much pressure will compress the cereal, making your treats dense and hard instead of delightfully chewy.
  • Grease Everything: Marshmallow mixture is notoriously sticky. Lightly grease your pot, spatula, hands, and the pan with cooking spray or butter to prevent frustrating sticking and make the process much smoother.
  • Work Quickly: Marshmallows begin to set as they cool. Have all your ingredients pre-measured and your pan prepared so you can work efficiently once the marshmallows are melted. This ensures uniform mixing and pressing.
  • Allow Adequate Cooling Time: While it’s hard to resist, give your treats sufficient time to cool and set completely before cutting. About 30-60 minutes at room temperature should do the trick. This makes for cleaner cuts and prevents the treats from falling apart.
  • Storage is Key: Store your finished Rice Krispies Treats in an airtight container at room temperature. They are best enjoyed the same day or within 2-3 days for optimal freshness and chewiness. Avoid refrigeration, as it can make them hard.

Eight Spooktacular Halloween Rice Krispies Treat Designs: Step-by-Step Guide

1. Ghoulish Zombie Rice Krispie Treats

Unleash your inner mad scientist with these delightfully gruesome zombie treats! They’re surprisingly simple to create and offer a fun, slightly spooky aesthetic that kids adore.

Ingredients

  • 5 prepared Rice Krispie Treats (cut into rectangular shapes)
  • 1 cup green candy melts + ½ tbsp coconut oil
  • 5 large chocolate chips (for one eye)
  • Chocolate jimmies (for the other eye and mouth details)
  • Pink confetti sprinkles (for rosy cheeks or brain-like texture)

How To Create Your Zombies
1. In a microwave-safe bowl, combine the green candy melts with coconut oil. Microwave in 30-second intervals, stirring until completely smooth and melted.
2. Dip each rectangular Rice Krispie Treat into the melted green candy, ensuring it’s fully coated. Gently shake off any excess and place it on a sheet of parchment paper to set.
3. While the green coating is still wet, carefully place one large chocolate chip onto each treat to create a zombie eye.
4. For the second eye, use a chocolate jimmie, pressing it lightly into the green coating. You can also use jimmies to create a jagged, stitched mouth.
5. Add pink confetti sprinkles for fun, slightly “undead” rosy cheeks, or scatter them to resemble a brain texture. Let them set completely at room temperature.

2. Charming Black Cat Halloween Rice Krispie Treats

Bring some feline charm to your Halloween party with these adorable black cat treats! They’re sleek, spooky, and always a crowd-pleaser.

Ingredients

  • 5 prepared Rice Krispie Treats (cut into square or circular shapes)
  • 1 cup chocolate chips (dark or semi-sweet) + ½ tbsp coconut oil
  • 10 candy eyes (for expressive eyes)
  • White jimmies (for whiskers)
  • 5 heart sprinkles (pink or red, for cute noses)
  • Small triangular chocolate pieces or black licorice for ears (optional)

How To Craft Your Black Cats
1. Melt chocolate chips with coconut oil in a microwave-safe bowl, stirring until smooth.
2. Dip each Rice Krispie Treat into the melted chocolate, coating it entirely. Allow excess chocolate to drip off, then place on parchment paper.
3. Immediately press two candy eyes onto each treat while the chocolate is still wet.
4. Place one heart sprinkle upside down just below the eyes for the nose.
5. Arrange 3-4 white jimmies on each side of the heart sprinkle to create adorable whiskers. If adding ears, press small triangular chocolate pieces (like cut chocolate almonds or small dark chocolate pieces) into the top corners.
6. Let your charming black cats set completely.

3. Ancient Mummy Rice Krispie Treats

Wrap your taste buds in mystery with these fun and simple mummy treats! They’re an iconic Halloween design that looks impressive but is incredibly easy to make.

Ingredients

  • 5 prepared Rice Krispie Treats (rectangular shapes work best)
  • 1 ¼ cups white chocolate chips + ½ tbsp coconut oil
  • 10 black sugar pearl sprinkles (for the mummy’s piercing eyes)

How To Embalm Your Mummies
1. Melt white chocolate chips with coconut oil in a microwave-safe bowl, stirring until silky smooth.
2. Dip each Rice Krispie Treat into the melted white chocolate, ensuring a good, even coating. Let any excess drip off, then place on parchment paper.
3. While the base layer is still wet, carefully position two black sugar pearls on each treat to form the mummy’s eyes.
4. Allow the initial white chocolate coat to set slightly, but not fully (about 5-10 minutes in the fridge can speed this up).
5. Transfer the remaining melted white chocolate into a piping bag fitted with a very small round tip (or simply snip a tiny corner off a Ziploc bag).
6. Pipe thin, haphazard lines across the treats, crisscrossing them to resemble mummy bandages, leaving the eyes peeking through.
7. Let the mummy treats set completely until the chocolate is firm.

4. Soaring Bat Halloween Rice Krispie Treats

These bat treats are a spooky delight, perfect for flapping into your Halloween dessert spread. They’re both cute and just a little bit creepy!

Ingredients

  • 5 prepared Rice Krispie Treats (rectangular or square)
  • 5 mini Reese’s Cups (for the bat’s body)
  • ¼ cup chocolate chips (for “glue” and optional details)
  • 10 candy eyes (for the bat’s watchful gaze)
  • 1 package Oreos (classic sandwich cookies)

How To Assemble Your Bats
1. Melt the ¼ cup of chocolate chips in a small microwave-safe bowl, stirring until smooth. Transfer this melted chocolate to a small piping bag or a Ziploc bag with a tiny corner snipped. This will be your “chocolate glue.”
2. Carefully twist apart each Oreo cookie, separating the two chocolate wafers. You’ll use these halves as the bat wings. Scrape off the cream filling if desired.
3. Pipe a small dot of melted chocolate onto the back of two Oreo halves. Press these onto the sides of a mini Reese’s Cup to form the bat’s wings and body.
4. Pipe another small dot of melted chocolate onto the back of the assembled Reese’s Cup body and press it onto the center of a Rice Krispie Treat.
5. Finally, use tiny dots of melted chocolate to attach two candy eyes to the top of the Reese’s Cup body, completing your bat’s face.
6. Allow all components to set and adhere completely before serving.

5. Creepy-Crawly Spider Halloween Rice Krispie Treats

Spin a web of deliciousness with these fun and slightly spooky spider treats. They’re a classic Halloween motif and surprisingly easy to assemble, perfect for any eerie gathering.

Ingredients

  • 5 prepared Rice Krispie Treats (rectangular or square)
  • 5 mini Reese’s Cups (for the spider’s body)
  • ⅓ cup chocolate chips (for “glue” and legs)
  • 10 candy eyes (for those eight-eyed stares)

How To Craft Your Spiders
1. Melt the chocolate chips in a microwave-safe bowl, stirring until smooth. Transfer this melted chocolate to a piping bag fitted with a very small round tip, or use a Ziploc bag with a tiny corner snipped off.
2. Using a tiny dab of melted chocolate, attach two candy eyes to the top of each mini Reese’s Cup. This forms the spider’s head.
3. Pipe another small dab of melted chocolate onto the bottom of the Reese’s Cup with the attached eyes, then press it firmly onto the center of each Rice Krispie Treat.
4. Once the Reese’s Cup is securely in place, use the piping bag to carefully draw four chocolate legs extending from each side of the Reese’s Cup onto the Rice Krispie Treat, creating a total of eight spider legs. Give them a slight bend for a more realistic, creepy-crawly effect.
5. Let your spider treats set completely on parchment paper until the chocolate has hardened.

6. Intricate Spider Web Rice Krispie Treats

Create a stunning visual effect with these artistic spider web treats. The contrast of dark chocolate and delicate marshmallow webs makes for a truly eye-catching dessert.

Ingredients

  • 5 prepared Rice Krispie Treats (rectangular or square)
  • 1 cup chocolate chips (dark or semi-sweet) + ½ tbsp coconut oil
  • 20 mini marshmallows

How To Weave Your Spider Webs
1. Melt chocolate chips with coconut oil in a microwave-safe bowl, stirring until smooth. Dip each Rice Krispie Treat into the melted chocolate, coating it thoroughly. Allow excess to drip off, then place on parchment paper to harden completely. This will form your dark, contrasting background.
2. In a separate microwave-safe bowl, place the mini marshmallows. Microwave them for 10-15 seconds, or until they puff up slightly. Watch carefully to avoid burning.
3. Immediately stir the puffed marshmallows with a spoon. As they cool slightly, they will become incredibly sticky and stringy.
4. Using your fingers (lightly greased if needed), grab a small clump of the melted, stringy marshmallows. Gently stretch and pull thin strands of marshmallow over the hardened chocolate-coated Rice Krispie Treats, creating intricate, delicate spider web patterns.
5. To secure the web, gently tuck the ends of the marshmallow strands into the sides of the treats.
6. Repeat for all treats. These are best enjoyed shortly after making to ensure the marshmallow remains soft and pliable.

7. Whimsical Witch Halloween Rice Krispie Treats

Conjure up some magic with these charming witch treats! Adorned with pointy hats and wart-like sprinkles, they are a wonderfully whimsical addition to your Halloween table.

Ingredients

  • 5 prepared Rice Krispie Treats (rectangular or square)
  • 1 cup green candy melts (or white chocolate with green food coloring) + ½ tbsp coconut oil
  • 10 candy eyes (for the witch’s gaze)
  • Chocolate jimmies (for hair and a quirky mouth)
  • 15 green pearl sprinkles (for warts)
  • 5 Oreos (split for hat brims)
  • 5 chocolate kisses (for hat peaks)
  • Small amount of melted chocolate (as “glue”)

How To Brew Your Witches
1. Melt green candy melts (or green-tinted white chocolate) with coconut oil, stirring until smooth. Dip each Rice Krispie Treat into the green coating, ensuring it’s fully covered. Smooth out any excess and place on parchment paper.
2. While the green coating is still wet, gently press two candy eyes onto each treat for the witch’s face.
3. Create a crooked, whimsical mouth using a single chocolate jimmie. Add more jimmies above the eyes for wild witch hair.
4. Scatter 2-3 green pearl sprinkles on each face to simulate warts, adding to the witchy charm.
5. To make the witch hats: Melt a small amount of chocolate. Pipe a dot of melted chocolate onto the flat side of an Oreo half (this is the hat brim). Press a chocolate kiss onto the center of the Oreo half to create the pointy hat. Let set.
6. Once the hats are firm, use another dab of melted chocolate to attach one hat to the top corner of each witch Rice Krispie Treat.
7. Let all elements set completely before serving your delightful witches.

8. Friendly Ghost Rice Krispie Treats

These classic ghost treats are simple, sweet, and perfect for Halloween. Their ethereal appearance makes them a perennial favorite for all ages.

Ingredients

  • 5 prepared Rice Krispie Treats (cut into various ghost-like shapes, e.g., slightly irregular rectangles or rounded tops)
  • 1 cup white chocolate chips + ½ tbsp coconut oil
  • 10 mini chocolate chips (for the ghost’s eyes)

How To Conjure Your Ghosts
1. Melt white chocolate chips with coconut oil in a microwave-safe bowl, stirring until smooth and fluid.
2. Dip each Rice Krispie Treat into the melted white chocolate, ensuring a thorough, even coating. Gently tap off any excess chocolate and place the coated treat onto parchment paper.
3. While the white chocolate is still wet, carefully place two mini chocolate chips onto each treat to create the ghost’s eyes. You can orient them for different expressions (e.g., surprised, sleepy).

Prep Time: 30 minutes
Time to Set: 1 hour
Total Time: 1 hour 30 minutes
Servings: 16 bars

Video

Equipment

  • 9 x 9-inch baking pan
  • Parchment paper
  • Large pot

Ingredients

  • Cooking spray
  • 5 tablespoons unsalted butter
  • 1 (16-ounce) bag miniature marshmallows divided
  • 6 cups Rice Krispies cereal
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract

Instructions

  • 1. Line a 9×9-inch baking pan with parchment paper or foil, ensuring an overhang on the sides for easy removal. Lightly spray the parchment/foil with cooking spray to prevent sticking. Set this prepared pan aside.
  • 2. In a large, sturdy pot, melt the unsalted butter over medium-low heat. Stir occasionally to prevent browning. As soon as the butter is fully melted, immediately reduce the heat to its lowest setting. Add 8 cups of the miniature marshmallows (reserving the remaining 2 ½ cups). Stir constantly with a heat-resistant spatula until the marshmallows are just melted and smooth. Be careful not to overcook, as this can lead to hard treats.
  • 3. Remove the pot from the heat. Stir in the salt (adjust to your preference if sensitive to salt) and vanilla extract. Immediately add the 6 cups of Rice Krispies cereal. Stir gently but thoroughly to coat all the cereal with the melted marshmallow mixture. Once the cereal is well coated, pour in the remaining 2 ½ cups of miniature marshmallows. Continue to stir until all ingredients are well incorporated and the new marshmallows are softened, creating pockets of chewiness.
  • 4. Pour the warm Rice Krispies mixture into your prepared 9×9-inch pan. Lightly spritz your hands with cooking spray or butter. Gently press the mixture evenly into the pan. Remember, do not press too hard, as firm packing will result in dense and hard treats rather than the desired soft and chewy texture. Set the pan aside at room temperature to cool and set, which typically takes about 30 minutes.
  • 5. Once cooled and firm, use the parchment paper overhang to lift the entire block of Rice Krispies Treats out of the pan. Place it on a cutting board. For easier and cleaner cuts, run a sharp knife under hot water for a few seconds, then dry it thoroughly with a towel before slicing. Cut the treats into desired shapes and sizes for decorating. Enjoy your delicious creations! These bars are best enjoyed on the same day they are made to maintain their optimal softness and freshness.
