How to Make Oreo Peanut Butter Bars
Phase 1 – Prep
STEP 1. Prepare the pan. Line an 8×8 inch pan with parchment paper or aluminum foil, leaving an overhang around the sides.
Phase 2 – Cook
STEP 2. Make the Oreo crust. Crush the Oreo cookies in a food processor until fine; mix with the melted butter and press into the base of the prepared pan.
STEP 3. Prepare the peanut butter layer. Beat the softened butter and brown sugar together until smooth. Mix in the peanut butter and salt until there are no lumps. Gradually add the powdered sugar until fully incorporated.
STEP 4. Spread the peanut butter layer. Spoon the peanut butter mixture over the Oreo crust and spread evenly.
STEP 5. Create the chocolate layer. Chop the chocolate into fine pieces and melt it in a microwave-safe bowl, stirring until smooth. Stir in the shortening, then pour over the peanut butter layer and spread to smooth out the top.
STEP 6. Let it set. Allow the chocolate to harden at room temperature or refrigerate it for faster setting.
STEP 7. Slice the bars. When the chocolate is about 90% hardened, score the top where you plan to slice. Once set, lift the bars out using the overhang and slice with a sharp knife.
Why This Recipe Works
This recipe creates a delightful texture balance between the crunchy crust and creamy filling. The warm melted chocolate binds the layers and amplifies the dessert’s richness. Each ingredient plays a role in enhancing flavor while maintaining a pleasant mouthfeel, ensuring your bars are a satisfying treat for any sweet craving.
