This Peanut Butter Cookie Lasagna is the kind of over-the-top dessert that makes everyone at the table stop talking mid-bite. Imagine layers of peanut butter cookies, fluffy peanut butter cheesecake filling, silky chocolate pudding, and clouds of whipped cream, all crowned with caramel, hot fudge, and extra cookie crumbles.

It’s rich and creamy, but the cookie layers keep every bite playful and fun—like an icebox cake and a peanut butter sundae had a very delicious baby. Best of all, it’s a no-bake dessert that you can make ahead, so it’s perfect for potlucks, holidays, or any night when turning on the oven feels like too much.

If you love peanut butter cookies and chocolate, this dessert is your happy place. The peanut butter sandwich cookies soften into almost cake-like layers, the cream cheese filling adds that tangy cheesecake vibe, and the chocolate pudding and hot fudge give you full-on sundae energy in every forkful.

This lasagna also looks wildly impressive with all those drips and layers, but the process is surprisingly simple. You’re mostly stirring, layering, and chilling—no fancy baking skills required. Plus, it’s easy to tweak: use crunchy or creamy peanut butter, swap in different cookies, or drizzle with extra caramel if you’re feeling bold.

For me, it’s all about texture. You get the gentle crunch of the cookie bits on top, the soft cookie layers in the middle, and that creamy, mousse-like peanut butter filling holding it all together. Every layer brings something different to the bite.

It’s also incredibly forgiving. As long as you let it chill long enough for the cookies to soften and the layers to set, it slices into beautiful squares that hold together but still feel lush and spoonable—exactly what you want from a dessert lasagna.

Before we start layering, let’s talk about what each ingredient is doing for you in this recipe. Since this is no-bake, every component matters for flavor and texture.

Peanut butter sandwich cookies – These are the “noodles” in our dessert lasagna, creating soft, peanutty layers as they soak up moisture from the filling.
Unsalted butter – Mixed with crushed cookies, it helps form a sturdy base that slices cleanly while still tasting rich and buttery.
Cream cheese – Brings a tangy cheesecake-style flavor and thick, creamy texture to the peanut butter layer so it holds its shape.
Creamy peanut butter – The star of the show, giving the filling its deep peanut flavor and extra richness.
Powdered sugar – Sweetens the peanut butter layer and dissolves easily so the filling stays smooth and fluffy.
Vanilla extract – Rounds out the flavors and adds that bakery-style warmth to both the filling and overall dessert.
Cold milk – Whisks into the instant pudding mix to create a silky chocolate layer that sets up nicely.
Instant chocolate pudding mix – Adds a luscious, chocolatey layer without any cooking—just whisk and pour.
Frozen whipped topping (thawed) – Lightens the peanut butter filling and makes a pillowy top layer that spreads like a dream.
Mini chocolate chips – Tuck into the layers and sprinkle on top for little pops of chocolate in every bite.
Hot fudge sauce – Provides that glossy, decadent chocolate drizzle that makes the lasagna look bakery-worthy.
Caramel sauce – Adds buttery, toasty sweetness and those gorgeous drips down the sides of each slice.
Flaky sea salt (optional) – A tiny sprinkle on top balances all the sweetness and makes the flavors pop.

Once you have everything ready, this dessert comes together in cozy, satisfying steps: crush, whisk, layer, and chill. Give yourself enough time for the lasagna to set in the fridge—this is when the magic happens.

Line a 9×13-inch baking dish with parchment paper if you’d like easy lifting later. Crush a generous portion of the peanut butter cookies into fine crumbs (a food processor or a rolling pin and bag both work). Stir the crumbs together with the melted butter until they resemble damp sand, then press firmly into the bottom of the pan to form an even crust. Pop the pan into the fridge while you mix the filling.

Step 2: Whip Up the Peanut Butter Cheesecake Layer

In a large mixing bowl, beat the softened cream cheese until completely smooth and free of lumps. Add the creamy peanut butter, powdered sugar, and vanilla, then beat again until thick, fluffy, and well combined. Fold in a portion of the whipped topping with a spatula to lighten the mixture—this gives you that mousse-like texture.

Step 3: Layer Peanut Butter Filling and Cookies

Spread half of the peanut butter filling over the chilled cookie crust in an even layer. Arrange a snug layer of whole peanut butter sandwich cookies over the top, pressing them lightly into the filling. Dollop the remaining peanut butter filling over the cookies and gently spread again, completely covering them.

Step 4: Make the Silky Chocolate Layer

In a separate bowl, whisk the cold milk and instant chocolate pudding mix together for a couple of minutes until thickened and glossy. Pour the pudding over the peanut butter layer and smooth it out with an offset spatula or the back of a spoon.

Step 5: Add Whipped Topping and All the Drizzles

Spread the remaining whipped topping over the chocolate pudding, creating soft swoops. Drizzle generously with warmed hot fudge sauce and caramel sauce so it cascades over the edges. Sprinkle the top with mini chocolate chips and roughly crumbled peanut butter cookies. If you’re using flaky sea salt, add just a pinch over the top.

Step 6: Chill Until Sliceable

Cover the dish tightly with plastic wrap or foil and refrigerate for at least 4 hours, or overnight for the cleanest slices. The longer it chills, the more the cookie layers soften and meld with the fillings. When you’re ready to serve, lift out (if you used parchment) and cut into neat squares with a sharp knife, wiping the blade between cuts.

This dessert is rich, so a little goes a long way. Cut the lasagna into 12 squares for a crowd-pleasing dessert that feels generous but not overwhelming. If you’re serving big sweet tooths, you can cut it into 9 larger portions.

Serve the slices well chilled so the layers stay distinct and the drizzles cling to the sides. For an extra-fancy touch, add a small spoonful of additional hot fudge or caramel on each plate, or a dollop of whipped cream on top.

Leftovers store beautifully. Cover the pan tightly or transfer slices to an airtight container and refrigerate for up to 4 days. The cookies will continue to soften, making the texture even more dreamy. You can also freeze individual slices, well wrapped, for up to 1 month—thaw overnight in the fridge before serving.

This Peanut Butter Cookie Lasagna is a showstopper all on its own, but pairing it with the right drinks and sides can turn dessert into a full experience.

Fresh Berries or a Simple Berry Salad

A bowl of fresh strawberries, raspberries, or mixed berries brings bright acidity and freshness that cuts through all the creamy richness.

Vanilla or Peanut Butter Ice Cream

For true dessert lovers, serve each slice with a scoop of vanilla or peanut butter ice cream. The cold, melty ice cream plays beautifully with the chilled, layered texture.

Hot Coffee or Espresso

A strong cup of coffee or a shot of espresso balances the sweetness and makes this dessert feel like something you’d order at a cozy café.

Cold Brew or Iced Latte

If it’s hot outside, pair your slice with a tall glass of cold brew or an iced latte. The bitterness of the coffee keeps each bite from feeling too heavy.

Tall Glasses of Cold Milk

Sometimes classic is best. A simple glass of milk—regular or dairy-free—is the most nostalgic companion to peanut butter and chocolate.

Salted Peanuts or Mixed Nuts

Set out a small bowl of lightly salted nuts. The crunch and saltiness give guests something to nibble between bites of creamy lasagna.

Light, Crisp Dessert Wine

For adults, a small pour of a sweet but crisp dessert wine can turn this into a dinner party finale without much extra effort.
