These easy Peanut Butter Oreo Bars are a dream come true for dessert lovers! Incredibly simple to prepare, they require no oven time, making them perfect for last-minute cravings or when you want a sweet treat without breaking a sweat. The creamy peanut butter filling layered over a crunchy Oreo base, all topped with a rich chocolate ganache, creates a symphony of textures and flavors that’s utterly satisfying. With a preparation time of just 20 minutes and a chilling time, you’ll be enjoying these delectable bars in no time.
Step-by-Step Instructions:
Prepare the Oreo Crust: In a medium bowl, combine the crushed Oreo cookies and melted butter. Stir well until all the cookie crumbs are evenly moistened. Press this mixture firmly into the bottom of an 8×8 inch baking pan that has been lined with parchment paper, leaving an overhang on the sides for easy lifting. Chill the crust in the refrigerator for at least 10 minutes while you prepare the filling.
Make the Peanut Butter Filling: In a separate bowl, beat together the creamy peanut butter, powdered sugar, and vanilla extract until smooth and well combined. If the mixture seems too stiff, you can add a tablespoon of milk or melted butter at a time until it reaches a spreadable consistency.
Assemble the Layers: Remove the chilled Oreo crust from the refrigerator. Evenly spread the peanut butter filling over the Oreo crust, ensuring it covers the surface completely. Smooth the top with a spatula for an even layer.
Prepare the Chocolate Topping: In a microwave-safe bowl, combine the semi-sweet chocolate chips and vegetable shortening (or coconut oil). Microwave in 30-second intervals, stirring between each interval, until the chocolate is completely melted and smooth. Stir until fully incorporated and glossy.
Finish the Bars: Pour the melted chocolate evenly over the peanut butter layer. Gently tilt the pan or use a spatula to spread the chocolate to the edges.
Chill to Set: Place the pan back in the refrigerator and chill for at least 30 minutes, or until the chocolate topping is firm. Once set, lift the bars out of the pan using the parchment paper overhang. Cut into squares or bars using a sharp knife.
