Ingredients You’ll Need

For this BOO! Chocolate Peanut Butter Bars Recipe, the ingredients blend together to create layers of flavor and texture. When shopping, I recommend using quality nut butter and fresh cereals to get the best results.

• Honey: Adds natural sweetness and helps bind the bar ingredients together.
• Maple Syrup: Provides a subtle depth of sweetness and enriches the flavor.
• Creamy Peanut Butter: I love using creamy for a smooth spread that melds perfectly with the cereals and chocolate.
• Corn Flakes Cereal: Gives crunch and lightness to balance the richness.
• Brown Rice Krispies: Adds crisp texture and a bit of wholesome whole grain.
• Semi-Sweet or Dark Chocolate: Choose good-quality chocolate to melt; it forms a luscious, glossy topping.
• White Chocolate: This is for creating those ghost shapes – it melts smoothly and decorates beautifully.
• Candy Eyes and Black Sprinkles: Essential for that spooky finishing touch—totally optional but so much fun!

Variations

I like to tweak the BOO! Chocolate Peanut Butter Bars Recipe depending on the occasion or what I have on hand. Feel free to adjust ingredients or shapes to suit your style and dietary needs—it’s very forgiving!

• Nut-Free Version: Swap peanut butter for sunflower seed butter, and use allergy-friendly cereals; my niece loved this alternative last Halloween!
• Extra Crunch: Add chopped nuts or seeds to the cereal mix if you want an added layer of texture.
• Vegan Option: Use maple syrup only (omit honey) and choose dairy-free chocolate varieties.
• Boo! Shapes: Instead of ghosts, try bats or pumpkins with colored candy melts—it’s a fun way to customize for your crowd.

How to Make BOO! Chocolate Peanut Butter Bars Recipe

Step 1: Prep and Mix the Crunchy Base

Start by lining a 9×13 inch baking dish with parchment paper—that makes cleanup a breeze and helps you lift the bars out easily later. In a large bowl, mix the corn flakes, brown rice krispies, and one cup of creamy peanut butter. This combo gives you that incredible crunch combined with creamy taste. Don’t rush this part; make sure all the cereals are evenly coated with peanut butter for even flavor in every bite.

Step 2: Make the Honey-Maple Syrup Binder

In a small saucepan, combine the honey and maple syrup and bring to a gentle boil over medium heat. Let it cook for about 2 minutes—this step thickens your binder so your bars hold together nicely without being sticky. Once done, remove from heat and quickly pour the warm syrup into your cereal and peanut butter mix. Stir thoroughly so every bit is coated before pressing it tightly into your prepared pan. Refrigerate for 15 minutes to set the base solidly.

Step 3: Melt and Spread the Chocolate Peanut Butter Topping

Grab your semi-sweet or dark chocolate along with a quarter cup of peanut butter and melt them together in the microwave in 30-second intervals, stirring in between. The peanut butter smooths out the chocolate and adds that extra richness I adore. Spread this luscious mixture evenly over the chilled cereal base. If you want your bars thicker, don’t hesitate to try a double coating next time!

Step 4: Create the Fun Ghost Decorations

Now for the best part: melting your white chocolate and dolloping it onto the dark chocolate layer to make ghost shapes. Use a spoon or skewer to gently swirl each dollop into a ghost — the imperfections make them look cuter and creepier. Leave about an inch of space between each ghost so they don’t merge when you cut. Place two mini candy eyes on each ghost, then pop the whole pan back into the fridge for another 15 minutes until everything is set. Once firm, cut around each ghost individually with a bit of unevenness — that’s the charm of these BOO! Chocolate Peanut Butter Bars!

How to Serve BOO! Chocolate Peanut Butter Bars Recipe

Garnishes

I love adding a sprinkle of black or orange sanding sugar over the bars for that extra sparkle and spooky vibe. You can also toss on some crushed peanuts or mini Halloween-themed sprinkles if you’re feeling fancy. These little touches make the bars pop and impress guests, especially kids!

Side Dishes

Pair these bars with a simple glass of cold milk or a warm cup of coffee or hot cocoa to balance the rich peanut butter and chocolate. They also go surprisingly well alongside fresh fruit, like crisp apple slices or berries, which help lighten the indulgence.

Creative Ways to Present

For Halloween parties, I love arranging these ghost bars on a black platter with fake spider webs draped around. Another favorite trick is to serve them in clear cupcake liners to keep them neat and portable. You can also stack them in a tiered dessert stand to make a spooky dessert buffet really stand out.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the fridge – they keep beautifully for up to 5 days. I find that refrigeration is key so the chocolate toppings don’t melt or get sticky. When you slice and store, keep parchment paper layered between bars to prevent sticking.

Freezing

Freezing these bars works great if you want to prep in advance. I wrap individual bars tightly in plastic wrap and place them in a freezer-safe bag. They thaw quickly at room temperature and still taste fresh; perfect if you want to make a batch early for a party.

Reheating

Since these bars are best served chilled or at room temperature, I don’t usually reheat them. If you prefer a softer texture, a quick 10-second zap in the microwave softens the chocolate topping without melting it completely, but I recommend enjoying them cold for that perfect bite.
