Introduction
These BOO! Chocolate Peanut Butter Bars are a fun and festive treat perfect for Halloween or any time you want a spooky sweet snack. Crunchy corn flakes and rice krispies combine with creamy peanut butter and rich chocolate to create irresistible ghost-shaped bars. Decorating them with candy eyes adds a playful touch that kids and adults alike will love.

Ingredients
- 3/4 cup honey
- 1/4 cup maple syrup
- 1 1/4 cups creamy peanut butter (divided)
- 3 cups corn flakes cereal
- 2 cups brown rice krispies
- 8-12 ounces semi-sweet or dark chocolate, melted
- 6 ounces white chocolate, melted
- Candy eyes and black sprinkles, for decorating
Instructions
- Step 1: Line a 9×13 inch baking dish with parchment paper for easy removal.
- Step 2: In a large bowl, combine the corn flakes, brown rice krispies, and 1 cup of the peanut butter.
- Step 3: In a small pot, mix the honey and maple syrup. Bring to a boil over medium heat and cook for 2 minutes. Remove from heat and pour over the cereal mixture, stirring well to combine.
- Step 4: Press the mixture firmly into the prepared baking dish. Chill in the fridge for 15 minutes to set.
- Step 5: Melt the semi-sweet or dark chocolate together with the remaining 1/4 cup peanut butter. Spread this chocolate layer evenly over the chilled cereal base.
- Step 6: Melt the white chocolate. Spoon small dollops (about 1 teaspoon for small ghosts or 1 tablespoon for larger ghosts), spacing them 1 inch apart on the chocolate layer. Use a skewer or the end of a spoon to drag the white chocolate into ghost shapes. Imperfections add to the spooky charm.
- Step 7: Place two mini candy eyes on each ghost. Return the bars to the fridge and chill for about 15 minutes to set the chocolate.
- Step 8: Cut around the ghosts into irregular shapes and keep the bars refrigerated until ready to serve.
Tips & Variations
- For a nut-free version, substitute peanut butter with sunflower seed butter and ensure your cereals are nut-free.
- Use dark chocolate for a richer taste or milk chocolate for a sweeter, creamier flavor.
- Swap candy eyes for small chocolate chips or edible markers to draw eyes for a customizable look.
Storage
Store the bars in an airtight container in the refrigerator for up to 5 days. They can also be frozen for up to 2 weeks; just thaw overnight in the fridge before serving. Reheat is not recommended as it may melt the chocolate decorations.

FAQs
Can I use a different cereal instead of corn flakes and rice krispies?
Yes, you can substitute with similar crispy cereals, but avoid overly sweet or sticky varieties to maintain the right texture and flavor balance.
How can I make the ghost shapes more defined?
Use a smaller spoon or piping bag for the white chocolate dollops and work quickly before the chocolate sets. However, the charm is in the imperfect shapes, so don’t worry about perfect designs.

Ingredients
Main Ingredients
- 3/4 cup honey
- 1/4 cup maple syrup
- 1 1/4 cups creamy peanut butter, divided
- 3 cups corn flakes cereal
- 2 cups brown rice krispies
- 8–12 ounces semi-sweet or dark chocolate, melted
- 6 ounces white chocolate, melted
- Candy eyes, for decorating
- Black sprinkles, for decorating
Instructions
- Prepare the Pan: Line a 9×13 inch baking dish with parchment paper for easy cleanup and to prevent sticking.
- Mix the Dry Ingredients: In a large bowl, combine the corn flakes, brown rice krispies, and 1 cup of creamy peanut butter. Stir these ingredients together to coat the cereal evenly.
- Make the Syrup: In a pot over medium heat, combine the honey and maple syrup. Bring to a boil and cook for 2 minutes to thicken slightly, then remove from heat.
- Combine & Press: Pour the hot syrup mixture into the cereal and peanut butter bowl. Stir well to thoroughly mix. Spread the mixture evenly into the prepared baking dish, pressing down firmly to compact. Refrigerate for 15 minutes to set.
- Melt Chocolate Topping: While the base sets, melt together the semi-sweet or dark chocolate with the remaining 1/4 cup peanut butter in the microwave until smooth. Spread this chocolate mixture evenly over the chilled cereal base.
- Create Ghosts: Melt the white chocolate separately. Spoon small dollops (about 1 teaspoon for small ghosts, 1 tablespoon for large ghosts) spaced roughly 1 inch apart over the chocolate layer. Using a wooden skewer or the end of a thin spoon, drag the white chocolate to form ghost shapes. Imperfections add character!
- Decorate: Press two mini candy eyes into each white chocolate ghost. Optionally, sprinkle black sprinkles around for an eerie effect.
- Set and Serve: Return the pan to the refrigerator and chill for about 15 minutes to set the chocolate. Cut around the ghost shapes, creating irregular bars. Keep refrigerated until serving to maintain texture and freshness.
