What Ingredients are in Peanut Butter Cookie Lasagna?
This dreamy no-bake dessert comes together with just a handful of simple ingredients you probably already have in your pantry and refrigerator.
- Graham crackers (for the layers)
- 8 oz cream cheese, softened
- 1 cup peanut butter
- 1 cup powdered sugar
- 8 oz whipped topping, divided
- 1 box vanilla instant pudding
- 1½ cups milk
- Chocolate chips (for topping)
When shopping for these ingredients, I recommend using regular graham crackers rather than cinnamon ones (unless you’re feeling adventurous), and creamy peanut butter works better than chunky for achieving that silky-smooth layer that makes this dessert so incredible.
How to Make this Peanut Butter Cookie Lasagna
Combine 8 oz of softened cream cheese, 1 cup of peanut butter, and 1 cup of powdered sugar in a large bowl.
Mix these ingredients until they’re completely smooth, making sure there aren’t any lumps hiding in there. This creates that irresistible peanut buttery base that makes this dessert so special.
Using a premium baking dish set will ensure even heat distribution and perfect results for your layered dessert.
Step 2: Fold in Half the Whipped Topping
Gently fold in half of your 8 oz container of whipped topping into the peanut butter mixture.
Don’t stir too vigorously—we want to keep all that fluffiness intact. The lighter your touch, the more cloud-like your peanut butter layer will be.
Step 3: Prepare the Pudding Layer
In a separate bowl, whisk together 1 box of vanilla instant pudding and 1½ cups of milk until the mixture thickens.
This usually takes about 2 minutes of whisking, and you’ll know it’s ready when it’s no longer liquidy but has a smooth, pudding-like consistency.
Step 4: Begin the Layering Process
Lay graham crackers in a single layer on the bottom of your dish, breaking them if needed to fit.
Think of this like laying down the foundation of an actual lasagna—you want complete coverage with no gaps showing through.
Step 5: Add the First Set of Layers
Spread half of your peanut butter mixture over the graham crackers, making sure to reach all the edges.
Then, carefully spread half of your vanilla pudding on top of that. The contrasting flavors are what make each bite so delightful.
Step 6: Repeat the Layers
Add another layer of graham crackers on top of the pudding, then repeat with remaining peanut butter mixture and pudding.
Finish with a final layer of graham crackers on top. These multiple layers are what give the dessert its “lasagna” name and create that perfect bite every time.
Step 7: Add the Finishing Touches
Spread the remaining half of your whipped topping over the top layer of graham crackers, creating a smooth, inviting surface.
Sprinkle chocolate chips generously across the top—they add both a pretty finish and a perfect chocolate accent.
Step 8: Chill Before Serving
Refrigerate your peanut butter cookie lasagna for at least 4 hours before serving, though overnight is truly ideal.
This chilling time allows the graham crackers to soften completely, transforming from crisp crackers into cake-like layers that meld with the creamy filling.
What to Serve with Peanut Butter Cookie Lasagna
This dreamy, layered dessert deserves perfect companions to round out your sweet treat experience. A scoop of vanilla ice cream alongside creates a delightful temperature contrast with the chilled lasagna.
For drinks, try serving with a cold glass of milk or a rich coffee—both cut through the sweetness beautifully.
If you’re hosting a dessert buffet, fresh berries on the side add a tart brightness that balances the rich peanut butter and cream cheese layers.
And for the chocolate lovers in your life, a drizzle of warm chocolate sauce over individual servings takes this already-decadent dessert to heavenly new heights.
This dessert works perfectly after dinner or as a special afternoon treat when you need something truly indulgent.
Peanut Butter Cookie Lasagna Substitutions and Variations
Looking to customize this dreamy dessert? Try these simple swaps and fun twists:

- Flavor Adventures: Swap in chocolate pudding for the vanilla, or mix mini peanut butter cups into the cream cheese layer. Banana slices between layers add a fruity twist!
- Seasonal Touches: Crushed candy canes make this festive for holidays, while chopped Reese’s Pieces create Halloween charm.

Leftovers and Storage for this Peanut Butter Cookie Lasagna
This no-bake dessert actually gets better with time! Here’s how to keep it perfect:
- Refrigerator Storage: Cover tightly with plastic wrap or transfer to an airtight container. Keeps beautifully for up to 5 days, with graham crackers becoming perfectly soft by day 2.
- Freezer Option: Yes, you can freeze it! Wrap individual portions in plastic, then foil, and freeze for up to 2 months. Thaw overnight in the refrigerator for best texture.
- Serving Tips: Let frozen portions sit at room temperature for 15-20 minutes before serving to soften slightly. For refrigerated leftovers, a quick 5-minute rest is all you need.
- Texture Note: The longer this dessert sits, the more the graham crackers soften into cake-like layers—many people prefer it on day 2 or 3 when all the flavors have fully melded together.
