- Chilling Time: 30 minutes
- Total Time: 50 minutes
This no-bake treat comes together in under an hour, with most of the time being hands-off while the bars chill.
Step-by-Step Instructions
Step 1: Prepare Your Pan and Cereal Base
Line a 9×13 inch baking dish with parchment paper, leaving an overhang on the sides for easy removal later. In a large bowl, combine the corn flakes, brown rice krispies, and 1 cup of the peanut butter. Mix well until the cereal is evenly coated.
Step 2: Create the Sweet Binder
In a small pot, combine the honey and maple syrup. Bring the mixture to a boil over medium heat and let it cook for 2 minutes. Immediately remove it from the heat and pour the hot syrup mixture into the cereal and peanut butter bowl. Stir well until everything is thoroughly combined.
Step 3: Press and Chill the Base
Spread the sticky cereal mixture into your prepared pan. Tip: Use a greased spatula or your hands to press the mixture down firmly and evenly into the pan. This tight packing is key to ensuring the bars hold their shape. Place the pan in the fridge to chill for 15 minutes.
Step 4: Add the Chocolate Peanut Butter Layer
While the base is chilling, melt together the semi-sweet or dark chocolate and the remaining ¼ cup of peanut butter in a microwave-safe bowl. Heat in 30-second intervals, stirring between each one, until smooth. Spread this rich chocolate mixture evenly over the chilled cereal base.
Step 5: Create the Adorable Ghosts
Melt the white chocolate until smooth. Spoon small dollops of the melted white chocolate onto the dark chocolate layer—use about 1 teaspoon for small ghosts and 1 tablespoon for larger ones, making sure to leave about an inch of space between each one. Using a wooden skewer or the skinny end of a spoon, gently drag the white chocolate downwards from the dollop to create a ghostly, wispy tail shape. Tip: Don’t worry about making them perfect! The more irregular and quirky they look, the better.
Step 6: Decorate and Set

While the white chocolate is still wet, insert two mini candy eyes into the “head” of each ghost. You can also add black sprinkles for a mouth if you like. Return the pan to the fridge to set completely, about 15 minutes more. Once firm, use a sharp knife to cut around the ghosts, creating fun, irregular-shaped bars. Boo!

Recipe Variations

- Make it Spooky: Use orange or green candy melts instead of white chocolate to create little monsters or aliens instead of ghosts.
Serving Suggestions

These Boo! Chocolate Peanut Butter Bars are the star of any Halloween spread.
- Party Platter: Arrange the ghost-topped bars on a platter for an easy and adorable party dessert that requires no plates or forks.
- Classroom Treats: These are a perfect, fun, and easy-to-handle treat for school Halloween parties (just be sure to check for nut allergies and use a nut-free alternative if needed).
- Boo Bags: Wrap individual bars in cellophane bags and tie them with an orange ribbon to “boo” your friends and neighbors with a surprise treat on their doorstep.
Common Mistakes to Avoid
- Base is Too Crumbly: This can happen if the base isn’t packed down tightly enough. Solution: Really press the cereal mixture firmly into the pan to ensure it holds together when you cut the bars.
- Chocolate Seizing: Melting chocolate too quickly will cause it to become thick and grainy. Solution: Always melt chocolate in short intervals in the microwave, stirring well in between, or use a double boiler on the stove.
- Messy Ghosts: Don’t stress about making your ghosts look perfect. Solution: Embrace the imperfections! A little wobble in your drag-and-swoop motion will give each ghost a unique personality.
Storing Tips
- Refrigeration is Key: These bars are best stored in the refrigerator to keep them firm and fresh. Place them in an airtight container, with parchment paper between layers to prevent sticking. They will last for up to 1 week.
- Freezing: These bars also freeze very well. Store them in a freezer-safe container for up to 3 months. Let them sit at room temperature for a few minutes before serving.

FAQs
Q1. Can I use a different kind of chocolate?
Yes! Milk chocolate or even peanut butter chips would work for the top layer, though dark or semi-sweet chocolate provides a nice flavor contrast and a dark “night sky” for your ghosts.
Q2. Where can I find candy eyes?
Candy eyes are usually available in the baking or seasonal aisle of most major grocery stores, especially around Halloween. You can also find them at craft stores or online.
Q3. Is this recipe gluten-free?
To make this recipe gluten-free, simply ensure that you are using certified gluten-free corn flakes and brown rice krispies, as not all brands are. The other ingredients are naturally gluten-free.
Q4. My bars are falling apart. What did I do wrong?
This is usually caused by not packing the base layer down firmly enough or not chilling it long enough before adding the chocolate topping. Really compacting that cereal mixture is the key to bars that hold together perfectly.
