Peanut Butter Lasagna

There’s something irresistibly nostalgic about a layered, no-bake dessert that marries crunchy cookies, creamy filling, and a glossy peanut butter topping. This Peanut Butter Lasagna is a crowd-pleaser—rich, cool, and perfectly balanced between sweet and salty. It’s built on a base of peanut butter sandwich cookies, a tangy cream cheese layer, silky pudding, and a cloud-like whipped topping. I love serving it chilled from the fridge so every slice holds its shape and every bite offers a contrast of textures.

Why you’ll love this Peanut Butter Lasagna

• Effortless assembly: no baking required, just mixer work and layering.

• Great for gatherings: it slices neatly and can feed a crowd.
• Make-ahead friendly: flavors deepen when chilled overnight, making it perfect for parties or potlucks.

Ingredients

Use a 9×13-inch dish for layering.

• 16 ounces peanut butter sandwich cookies
• 8 ounce cream cheese (softened to room temperature)
• 1 cup powdered sugar
• 1 cup whipped topping
• 3.4 ounces instant vanilla pudding

Notes on ingredients

All ingredients have been selected to keep the dessert suitable for a wide audience. The sandwich cookies provide a sturdy, flavorful crust; cream cheese adds a slight tang that contrasts beautifully with the sweet pudding and peanut butter. Whipped topping is used in multiple layers for lightness; if you prefer, use a dairy-free whipped topping substitute that matches your taste. The peanut butter chips give bursts of concentrated peanut flavor, and the reserved cookie pieces add a final crunch.

Equipment

• 9×13-inch baking dish
• Large mixing bowl
• Medium mixing bowl

Step-by-step directions

Follow these directions in order to assemble your Peanut Butter Lasagna. I’ve rewritten the steps for clarity while keeping the amounts and sequence faithful to the ingredient list.

1. Prepare the cookie base: Place the 16 ounces of peanut butter sandwich cookies in a large bowl or food processor and crush them into fine crumbs. Press the crumbs evenly into the bottom of a 9×13-inch dish to form a compact crust. Use the bottom of a flat measuring cup or a glass to press down so the base is firm and level.
2. Make the cream cheese layer: In a medium mixing bowl, beat the 8 ounce softened cream cheese until smooth and creamy. Gradually add 1 cup powdered sugar and continue to beat until well combined and silky. Fold in 1 cup whipped topping gently with a spatula until the mixture is uniform and light in texture.
3. Spread the cream cheese layer: Spoon the cream cheese mixture over the pressed cookie crust and spread it into an even layer. Smooth the top with an offset spatula or the back of a spoon so the next layer will sit evenly.
4. Prepare the pudding layer: In a separate bowl, whisk together the 3.4 ounces instant vanilla pudding mix with 1½ cups whole milk. Whisk briskly for about two minutes until the pudding begins to thicken. Let it sit for a minute to fully set.
5. Layer the pudding: Once the pudding has thickened, spread it over the cream cheese layer in an even layer, covering the cream cheese completely to create the third layer of this lasagna.
6. Mix the peanut butter layer: In another bowl, combine 1 cup creamy peanut butter with 1 cup whipped topping. Stir or beat until smooth and uniform in texture. This creates a lighter peanut butter filling that won’t be too dense.
7. Add the peanut butter layer: Spread the peanut butter and whipped topping mixture evenly over the pudding layer. Smooth the surface so the next topping adheres well.
8. Create the whipped topping cap: Take the remaining 2 cups whipped topping and spread it evenly over the peanut butter layer to form a fluffy top. This final whipped topping keeps the dessert airy and provides a pretty surface for the garnishes.
9. Garnish with chips and cookie pieces: Evenly sprinkle ½ cup peanut butter chips across the top of the whipped topping. Next, scatter the 8 reserved whole peanut butter cookies that you chopped into pieces over the surface for added texture and visual interest.
10. Drizzle with melted peanut butter: Place ½ cup creamy peanut butter in a microwave-safe bowl and microwave in short bursts (10–15 seconds), stirring between each burst until the peanut butter is just melted and pourable. Drizzle the melted peanut butter over the top of the lasagna in a decorative pattern. Be careful not to overheat; you want a smooth drizzle.
11. Chill before serving: Cover the dish with plastic wrap or foil and chill in the refrigerator for at least 4 hours, but preferably overnight. Chilling allows the layers to set and the flavors to meld, making slicing cleaner and easier.
12. Slice and serve: Remove the lasagna from the refrigerator about 10 minutes before slicing to make cutting smoother. Use a sharp knife dipped in hot water and wiped dry between cuts for neat slices. Serve cold and enjoy.

Tips and variations

• For extra crunch, fold some chopped cookie pieces into the peanut butter layer before spreading it.
• If you prefer a less sweet version, reduce the powdered sugar by 2–3 tablespoons in the cream cheese layer.
• Swap the peanut butter chips for dark chocolate chips for a delicious contrast.
• To make individual portions, assemble in small glasses or ramekins following the same layering order.
• To ensure smooth drizzling, thin the melted peanut butter with a teaspoon of neutral oil if necessary.

Storage

Keep any leftovers covered in the refrigerator for up to 4 days. The lasagna slices hold their shape best when chilled, so try to avoid leaving it at room temperature for extended periods. If you need to freeze slices, wrap them individually in plastic wrap and then in foil; thaw in the refrigerator before serving.

Serving suggestions

Serve slices with a cold glass of milk or a cup of coffee. A few extra cookie crumbs or a sprinkle of peanut butter chips on each slice right before serving adds a pretty finishing touch. If you’d like a bright counterpoint, add a few thin apple slices or a small dollop of fresh berries on the side.

Final thoughts

This Peanut Butter Lasagna is a playful take on layered desserts, perfect for anyone who loves peanut butter in every form. It’s simple to make, stores well, and travels nicely—ideal for potlucks, family meals, or when you want an easy, shareable dessert that still feels special. The combination of the cookie crust, tangy cream cheese layer, smooth pudding, and multiple whipped layers keeps every forkful interesting and satisfying.
