Ingredients You’ll Need

All the ingredients for this BOO! Chocolate Peanut Butter Bars Recipe come together to create a wonderfully crunchy, chocolaty, and peanut buttery treat. The combination of corn flakes and brown rice krispies gives it that perfect texture, while the mix of honey and maple syrup adds a natural sweetness. Here are the stars you’ll be working with:

• Honey: This natural sweetener adds a lovely floral note and helps everything stick together.
• Maple syrup: Adds depth and warmth to the sweetness, balancing the peanut butter beautifully.
• Creamy peanut butter: Make sure it’s smooth for easy mixing and that indulgent creamy flavor.
• Corn flakes cereal: Provides a light and crispy crunch that doesn’t get soggy too fast.
• Brown rice krispies: Another crispy element that complements the corn flakes for a great texture mix.
• Semi-sweet or dark chocolate: Choose your favorite for a rich coating that’s not too sweet.
• White chocolate: For making those ghostly dollops you’ll shape into adorable spooky figures.
• Candy eyes and black sprinkles: This is where the magic happens—adding personality and fun to your ghosts!

Variations

I love how flexible this BOO! Chocolate Peanut Butter Bars Recipe is—you can easily tweak it to your taste or dietary needs. I often adjust the chocolate types or add a sprinkle of sea salt for a salty-sweet contrast. Don’t be afraid to make it your own!

• Nut-Free Variation: When hosting friends with allergies, I swap peanut butter for sunflower seed butter, and opt for dairy-free chocolate. It still tastes amazing and everyone loves it!
• Extra Crunch: Sometimes I toss in chopped nuts or pretzel pieces for an added crunch and saltiness that my family goes crazy for.
• Healthier Twist: You can replace the cereals with puffed quinoa for a higher protein bite and less sugar.

How to Make BOO! Chocolate Peanut Butter Bars Recipe

Step 1: Prep Your Pan and Mix Cereals with Peanut Butter

Start by lining a 9×13 inch baking dish with parchment paper—this really saves time later when you’re removing the bars. In a large bowl, combine the corn flakes, brown rice krispies, and 1 cup of creamy peanut butter. Using your hands or a sturdy spoon, gently mix to combine everything well. The peanut butter will help bind the cereals, giving you that perfect chew and crunch balance.

Step 2: Create the Sweet Syrup and Combine

In a small pot over medium heat, combine the honey and maple syrup. Bring this mixture to a light boil and let it cook for 2 minutes while stirring occasionally. This combines the flavors and thickens it slightly. Pour this hot syrup into your cereal and peanut butter bowl, then mix quickly but thoroughly. Once mixed, spread the mixture firmly into your parchment-lined pan. Press down firmly to make sure it holds together well after chilling. Pop it in the fridge for about 15 minutes to set.

Step 3: Melt Chocolate and Spread

While the base chills, melt your semi-sweet or dark chocolate with the remaining ¼ cup of peanut butter in the microwave. I like to do this in short 20-second bursts, stirring between each until smooth. This creates a silky peanut butter chocolate topping that’s a match made in heaven. Once melted and combined, spread this evenly over the chilled cereal base. Return the pan to the fridge for another 15 minutes to let the chocolate layer firm up.

Step 4: Shape the Ghosts with White Chocolate

Next, melt your white chocolate to use for the ghost shapes. Using a teaspoon for smaller ghosts or a tablespoon for larger ones, dollop the white chocolate onto the dark chocolate layer, spacing each dollop about an inch apart. Then, grab a wooden skewer or the end of a skinny spoon and gently drag the white chocolate downward to create ghostly shapes. Don’t worry if they aren’t perfectly symmetrical—the character is in the imperfection! Add two mini candy eyes to each ghost for that iconic look.

Step 5: Chill, Cut, and Serve Your BOO! Chocolate Peanut Butter Bars

Put the entire pan back into the fridge for about 15 minutes to let the white chocolate ghosts set solid. When ready, carefully cut around each ghost shape, creating irregular edges that add to their spooky charm. Keep your bars chilled until you’re ready to serve—these are best straight from the fridge, but they’re still delicious at room temp!

How to Serve BOO! Chocolate Peanut Butter Bars Recipe

Garnishes

I like to finish these bars off with extra candy eyes or sprinkle some black sanding sugar or edible glitter to enhance the ghostly effect. Sometimes, a few tiny edible pumpkins or stars add a fun fall touch when serving guests. It’s a simple way to make the presentation feel extra special without any stress.

Side Dishes

These bars shine as a standalone treat, but for a party, I love pairing them with a scoop of vanilla ice cream or a dollop of whipped cream to complement the chocolate and peanut butter flavors. A cup of spiced pumpkin latte or hot chocolate alongside amps up the cozy vibes perfectly.

Creative Ways to Present

For Halloween gatherings, I’ve cut these bars into mini “ghost stacks” by layering with thin slices of marshmallow or white chocolate between bars, held together with a cute themed toothpick. I’ve also used black serving trays or orange plates to really make those white chocolate ghosts pop visually. Adding tiny eerie accessories like fake cobwebs around the serving tray turns it into a real conversation starter!

Make Ahead and Storage

Storing Leftovers

I usually store leftover bars in an airtight container in the fridge. This keeps them fresh for about 5 days. Because of the chocolate topping, they hold their texture well chilled and don’t get too sticky or soggy. Just make sure to keep them separated with parchment paper when stacking to avoid sticking.

Freezing

Freezing works great if you want to prep these bars in advance. Wrap individual bars or pieces tightly in plastic wrap and place in an airtight freezer-safe container. They can last up to 2 months this way. When thawing, I recommend moving them to the fridge overnight to avoid condensation ruining that beautiful chocolate layer.

Reheating

There’s no need to reheat these bars since they’re best enjoyed chilled or at room temperature. But if you prefer a softer chocolate layer, you can leave them at room temp for 10-15 minutes before serving. Just don’t microwave or heat directly—it can melt your intricate ghost designs!
