Peanut Butter Lasagna is absolutely one of the most addictive no-bake desserts I’ve ever created, and I cannot get enough of how the layers of Oreo crust, creamy peanut butter filling, chocolate pudding, and whipped cream create the ultimate peanut butter cup experience in lasagna form. The combination of crunchy chocolate cookie base, fluffy peanut butter mousse, rich chocolate pudding, and light whipped topping makes every single bite incredibly satisfying. What makes this dessert so special is how easy it is to make with no baking required, yet it looks absolutely stunning when you slice into it and reveal those gorgeous layers.

What Is Peanut Butter Lasagna?

Peanut Butter Lasagna is a no-bake layered dessert made with an Oreo cookie crust, creamy peanut butter layer, chocolate pudding layer, and whipped cream topping all in a 9×13 inch pan. What makes this dessert special is how the layers create the flavor profile of a peanut butter cup but in a light creamy form. The Oreo crust adds chocolate crunch while the peanut butter and cream cheese mixture stays fluffy. The chocolate pudding brings rich flavor and the whipped topping adds lightness. Think of it as a deconstructed peanut butter cup that serves a crowd perfectly.

What You’ll Need

Let’s break down all the ingredients for this delicious Peanut Butter Lasagna. I’ve organized everything by layer.

For the Oreo Crust:

Oreo cookies (36 cookies): About one package. Includes cream filling for your Peanut Butter Lasagna.
Melted butter (1/3 cup): Binds the crust together.

For the Peanut Butter Layer:

Cream cheese (8 ounces, softened): Must be room temperature for smooth mixing.
Creamy peanut butter (1 cup): Regular creamy works best for your Peanut Butter Lasagna. Not natural.
Powdered sugar (1 cup): Sweetens and stabilizes.
Milk (1/4 cup): Thins the mixture for spreading.
Whipped topping (1 1/2 cups): Cool Whip or homemade. Adds lightness.

For the Chocolate Layer:

Instant chocolate pudding mix (2 boxes, 3.4 ounces each): 4-serving size boxes for your Peanut Butter Lasagna.
Milk (2 3/4 cups): Less than box directions. Makes thicker pudding.

For the Topping:

Whipped topping: Cool Whip or homemade.
Mini Reese’s Peanut Butter Cups (1 package): Chopped for garnish.
Peanut butter chips: For sprinkling on top of your Peanut Butter Lasagna.
Chocolate syrup (optional): Drizzle for decoration.

Step-by-Step Instructions

Alright, let’s make this amazing no-bake dessert. Each layer is simple and builds perfectly.

Make the Oreo Crust

In a food processor, finely crush Oreo cookies. You want them like fine crumbs. Stir in melted butter until mixture looks like wet sand for your Peanut Butter Lasagna.

Press mixture into a 9×13 inch pan or glass dish. Press firmly and evenly to create solid base. Place in the freezer while preparing the next layer. This helps it set.

Make the Peanut Butter Layer

With mixer on medium speed, beat cream cheese, milk, and peanut butter until fluffy. This should take about 2 minutes. Slowly add in powdered sugar and beat until smooth for your Peanut Butter Lasagna.

Gently fold in whipped topping with a spatula. Don’t overmix or you’ll deflate the whipped topping. Spread the peanut butter layer evenly on the Oreo crust. Place in the freezer while preparing the next layer.

Make the Chocolate Layer

In a bowl, mix together both boxes of pudding mix and milk. Note that this is less milk than called for on the box. You want this layer a little bit thicker than regular pudding for your Peanut Butter Lasagna.

Spread the pudding onto the peanut butter layer evenly. Work quickly as pudding starts to set. Place in the fridge and allow to set for about 5 minutes before topping.

Add the Toppings

Top with remaining whipped topping, spreading evenly over the chocolate pudding. Sprinkle with chopped Reese’s Mini Pieces and peanut butter chips for your Peanut Butter Lasagna. Drizzle with chocolate sauce if desired.

Refrigerate at least 3 hours before serving. Overnight is even better as layers set completely. Cut into squares to serve.

Serving This Showstopper

This Peanut Butter Lasagna is best served cold, cut into squares that reveal the beautiful layers of Oreo crust, peanut butter filling, chocolate pudding, and whipped cream. I love serving it at potlucks, birthday parties, or holiday gatherings because it feeds a crowd and everyone loves the peanut butter cup flavor. The combination of textures from crunchy to creamy creates incredible experience. For a complete chocolate peanut butter spread, serve it alongside other treats like my Peanut Butter Chocolate Mousse Cake to give guests variety. Store covered in the refrigerator for up to 5 days.

Pro Tips for Success

Crush Oreos finely: Fine crumbs create better crust for your Peanut Butter Lasagna. Food processor works best.
Press crust firmly: Creates solid base that won’t crumble when cutting.
Room temperature cream cheese essential: Cold cream cheese won’t mix smooth. Lumpy layer results.
Use regular peanut butter: Not natural. Natural separates and won’t set properly.
Fold whipped topping gently: Don’t stir vigorously or you deflate it.
Less milk in pudding: Makes thicker layer that holds shape for your Peanut Butter Lasagna.
Freeze between layers: Helps each layer set before adding next one.
Chill minimum 3 hours: Overnight is better. Layers need time to set completely.
Clean knife between cuts: Wipe knife after each slice for neat presentation.
Garnish generously: Reese’s and peanut butter chips make it look amazing for your Peanut Butter Lasagna.

Common Questions Answered

Can I use homemade whipped cream?

Yes! Stabilized whipped cream works great for your Peanut Butter Lasagna. Add 1 tablespoon powdered sugar per cup of heavy cream and whip to stiff peaks. Cool Whip is easier and holds up better for several days though.

Why can’t I use natural peanut butter?

Natural peanut butter has oils that separate and won’t create the stable creamy layer needed. Regular creamy peanut butter like Jif or Skippy has stabilizers that help the layer set properly and stay smooth.

Can I make this ahead?

Yes! This is perfect for making ahead for your Peanut Butter Lasagna. Make it 1-2 days before serving. Keep refrigerated and covered. The layers actually set better when made ahead. Just add final garnishes before serving.

How do I get clean slices?

Use a sharp knife dipped in hot water and wiped clean between each cut. Make sure the dessert is well chilled. The first slice is always messy but gets easier after that.
