First Step: 1-Gather and Prep Your Ingredients Start by lining an 8×8 inch baking dish with parchment paper for easy removal later. Measure out 2 cups of crushed Oreo cookies and set them aside in a large bowl. This preparation ensures your Oreo peanut butter bar recipe goes smoothly and adapts to dietary needs like gluten-free options.

Second Step: 2-Mix the Base In the same bowl, add 1 cup of creamy peanut butter and 1/2 cup of melted unsalted butter. Stir until fully combined, creating a thick mixture that forms the heart of your no-bake dessert. For a low-calorie twist, swap in unsweetened applesauce if you’re watching your intake, making these easy peanut butter Oreo bars even more versatile.

Third Step: 3-Add Sweetness and Flavor Gradually mix in 2 cups of powdered sugar until the mixture is smooth and holds together. Drizzle in 1 tablespoon of vanilla extract for that extra flavor pop. At this stage, if you’re aiming for a vegan version, use coconut oil instead to keep your Oreo peanut butter bars aligned with plant-based preferences.

Fourth Step: 4-Press and Chill Press the mixture firmly into your prepared dish, ensuring an even layer. Pop it in the fridge for at least 2 hours to set this is key for that perfect texture in your decadent no-bake dessert. While chilling, think about how this step makes the bars easy to slice and serve for any occasion.

Fifth Step: 5-Add Toppings and Serve Once chilled, sprinkle 1/2 cup of chocolate chips on top if desired, and cut into squares. Serve immediately for the best taste, as these Oreo peanut butter bars can soften after about an hour at room temperature.
