How to Make Peanut Butter Oreo Bars
Prepare Your Base: Start by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking pan with cooking spray or line it with parchment paper for easy removal.
Crush Oreos: In a mixing bowl, crush approximately 24 Oreo cookies into fine crumbs using a food processor or by placing them in a ziplock bag and smashing away. The finer, the better!
Create Peanut Butter Mixture: In another bowl, combine one cup of creamy peanut butter with half a cup of softened unsalted butter and mix until smooth and creamy. Add about two cups of powdered sugar gradually until fully combined.
Layer It Up: Press half of your crushed Oreos evenly into the bottom of your prepared pan. Spread half of the peanut butter mixture over this layer, smoothing it out gently.
Add Chocolate Topping: Melt one cup of chocolate chips in a microwave-safe bowl in 30-second intervals. Stir until smooth and pour over the second layer. Top with remaining Oreo crumbs.
Cool and Serve: Refrigerate for at least two hours or until set. Slice into squares and serve chilled or at room temperature—either way, they’re divine!
