Ingredients You’ll Need

Here’s what you’ll need to make this peanut butter lasagna taste like a slice of dessert paradise:

Chocolate sandwich cookies: These form the base of the lasagna. Crush them into crumbs for a buttery, crunchy layer.
Butter: Used to bind the cookie crumbs into a firm crust that holds all the creamy layers.
Cream cheese: Adds tang and structure to the peanut butter layer. Make sure it’s softened for easy mixing.
Peanut butter: The star of the show—choose a creamy version for the smoothest texture.
Powdered sugar: Sweetens and firms up the peanut butter layer without making it gritty.
Whipped topping: Adds lightness and volume. Use it in both the peanut butter filling and as the final topping.
Instant chocolate pudding mix: For a rich, velvety chocolate layer that sets quickly and adds depth of flavor.
Milk: Needed to activate and thicken the pudding mix. Cold milk works best for proper consistency.
Chocolate chips or shavings: Optional, but highly recommended for garnishing the top with extra chocolatey flair.
Crushed peanuts or chopped peanut butter cups: Perfect for a crunchy finish and even more peanut butter goodness.

Variations

Want to tweak your peanut butter lasagna to make it your own? Here are some delicious ways to switch it up:

Nutella Twist: Replace the peanut butter with Nutella for a hazelnut-chocolate version.
Oreo Overload: Use flavored sandwich cookies like peanut butter or double-stuffed Oreos for an extra layer of flavor.
Banana-Peanut Butter: Add thin banana slices between the peanut butter and pudding layers for a classic combo.
Crunch Factor: Mix crushed pretzels into the crust or sprinkle on top for a salty crunch.
Mini Cups: Instead of making one large pan, layer the dessert into individual serving cups for a fun party treat.

How to Make Decadent Peanut Butter Lasagna

Step 1: Make the Cookie Crust

Crush the chocolate sandwich cookies into fine crumbs and mix them with melted butter. Press the mixture firmly into the bottom of a 9×13-inch dish to form the crust. Place it in the fridge to set while you work on the next layer.

Step 2: Create the Peanut Butter Layer

In a large bowl, beat the softened cream cheese until smooth. Add in the peanut butter and powdered sugar and beat until creamy. Fold in a generous scoop of whipped topping until light and fluffy. Spread this mixture evenly over the chilled crust.

Step 3: Add the Chocolate Layer

Prepare the instant chocolate pudding according to package directions using cold milk. Let it sit for a couple of minutes to thicken, then carefully spread it over the peanut butter layer.

Step 4: Top It Off

Spread the remaining whipped topping over the chocolate layer for a fluffy finish. Garnish with chocolate chips, crushed peanuts, or chopped peanut butter cups.

Step 5: Chill and Serve

Let the lasagna chill in the refrigerator for at least 4 hours (or overnight) to fully set. Slice into squares and serve cold.

Pro Tips for Making the Recipe

Use cold milk for the pudding to ensure it sets properly—warm or room-temp milk can leave it runny.
Chill thoroughly before serving. The longer it rests in the fridge, the better the layers hold together.
Don’t skimp on the crust. Make sure to press it down firmly with a flat-bottomed cup or spatula for a solid base.
Softened cream cheese is crucial for a lump-free peanut butter layer. Let it sit at room temperature for about 30 minutes before mixing.
Make clean cuts by wiping your knife between slices for picture-perfect servings.

How to Serve

This peanut butter lasagna is made to shine on its own, but a few pairings can take it to the next level:

Serve With:

A glass of cold milk or a hot cup of coffee for contrast.
A drizzle of warm chocolate or caramel sauce for extra indulgence.
A scoop of vanilla or peanut butter ice cream for dessert heaven.

Presentation Ideas:

FAQs

Natural peanut butter can be used, but it may separate and affect the creamy texture. If you do use it, stir thoroughly and add a bit more powdered sugar to firm up the layer.

Can I make this dessert ahead of time?
Absolutely! This is a fantastic make-ahead dessert. It needs several hours to chill, so making it the night before is ideal.

Can I use homemade whipped cream instead of store-bought topping?
Yes, you can. Just make sure it’s whipped to stiff peaks and stabilized if possible so it holds its shape.

Is this recipe gluten-free?
It’s not by default, but you can easily make it gluten-free by using gluten-free chocolate sandwich cookies and ensuring the pudding mix is certified gluten-free.
