Step-by-Step Guide to Making Reese’s Peanut Butter Captain Crunch Bars
Step 1: Prepare the Pan
Line your pan with parchment paper, leaving some overhang for easy lifting later. Lightly grease if preferred.
Step 2: Melt the Base
In a medium saucepan over medium heat, melt butter. Add corn syrup and peanut butter, stirring until smooth. Add marshmallows and stir until creamy. Remove from heat, add vanilla if using.
Step 3: Mix with Cereal
Pour Captain Crunch cereal into a large bowl. Add the peanut butter-marshmallow mixture. Stir until every piece is coated.
Step 4: Press the Mixture
Transfer mixture to your prepared pan. Use a greased spatula or hands to press evenly and firmly.
Step 5: Melt Chocolate & Chips
In a microwave-safe bowl, combine semi-sweet chocolate chips and Reese’s peanut butter chips. Heat in 20-second intervals, stirring each time, until smooth.
Step 6: Spread the Topping
Pour chocolate mixture over the pressed cereal bars. Spread evenly with a spatula.
Step 7: Chill & Slice
Let bars set at room temperature or refrigerate for 1–2 hours. Once firm, lift from the pan using parchment, cut into squares, and serve.
