Step‑by‑Step Instructions for Peanut Butter Lasagna
Step 1: Crush the Crust
Begin by placing your Oreo cookies in a food processor and pulse them until they become fine crumbs. In a separate bowl, melt 6 tablespoons of unsalted butter, then combine it with the crushed cookies. Stir until evenly coated. Press this mixture firmly into the bottom of a 9×13-inch baking dish to form a solid crust; it should look dark and crumbly.
Step 2: Prepare the Peanut Butter Layer
In a large mixing bowl, beat together 8 ounces of softened cream cheese, 1 cup of peanut butter, ¾ cup of powdered sugar, and 1 teaspoon of vanilla extract. Use an electric mixer on medium speed until the mixture is smooth and creamy, about 3-5 minutes. Carefully fold in half of an 8-ounce container of thawed whipped topping until fully combined and fluffy.
Step 3: Layer the Peanut Butter Mixture
Spread the creamy peanut butter mixture evenly over the prepared Oreo crust in your baking dish. Use a spatula to gently smooth it into an even layer, ensuring that it reaches the corners. This layer should be rich and glossy, showcasing the beautiful, luscious peanut butter flavor that defines your Peanut Butter Lasagna.
Step 4: Make the Chocolate Layer
In a separate mixing bowl, combine the contents of 2 boxes (3.4 ounces each) of instant chocolate fudge pudding with 3 cups of cold whole milk. Whisk the mixture vigorously for about 2 minutes until it thickens to a pudding-like consistency. Once thickened, pour this layer over the peanut butter layer, spreading it evenly with a spatula for a polished, decadent finish.
Step 5: Chill Your Masterpiece
Cover the dish with plastic wrap and place it in the refrigerator. Allow the Peanut Butter Lasagna to chill for at least 2 hours; for best results, chill it overnight. This step is crucial as it allows all the layers to meld together, resulting in a creamy texture that is easy to slice and serve.
Step 6: Add the Final Touches
Before serving, remove the dish from the refrigerator and spread the remaining 8 ounces of whipped topping evenly over the top layer. Feel free to get creative by garnishing with crushed peanuts or a drizzle of chocolate sauce. This finishing touch not only enhances the flavor but also adds an inviting visual appeal to your amazing Peanut Butter Lasagna.

What should I do if my pudding layer didn’t thicken properly?
If your pudding layer isn’t thickening as expected, it could be due to not using cold milk or not whisking for long enough. Make sure to use cold whole milk and whisk vigorously for about 2 minutes. If it’s still too runny, try refrigerating it for 15-20 minutes to see if it thickens up as it chills. You can also add a little more pudding mix if necessary, blending it in well.

If you or your guests have dietary restrictions, consider alternatives like a gluten-free cookie for the crust or vegan cream cheese and whipped topping to make it dairy-free. Additionally, check for peanut allergies; swapping peanut butter for almond butter can be a tasty option if the allergy permits. Always make sure to tailor your ingredients based on the dietary needs of your loved ones!

Very! Chilling is a crucial step, allowing all the flavors to meld beautifully and the layers to set properly. For the best results, aim to chill the dessert for at least 2 hours, but overnight is even better! This not only enhances the texture but makes it much easier to slice and serve.
