Peanut Butter Lasagna is a chilled, layered dessert that tastes like a peanut butter cup in “lasagna” form—no noodles, no oven, just creamy layers over a cookie crust. It’s rich, chocolatey, and perfect for make-ahead parties because it slices beautifully after chilling
Ingredients
1) Cookie Crust
- 24 Oreo cookies (about 2 cups crushed, filling included)
- 5 tbsp (70 g) unsalted butter, melted
2) Peanut Butter Cheesecake Layer
- 8 oz (225 g) cream cheese, softened
- 1 cup (240 g) creamy peanut butter
- 1 cup (120 g) powdered sugar
- 1 tsp vanilla extract
- 1½ cups (360 ml) whipped topping (or homemade whipped cream)
3) Chocolate Pudding Layer
- 1 box (3.4 oz / 96 g) instant chocolate pudding mix
- 1¾ cups (420 ml) cold milk
4) Topping
- 1½ cups (360 ml) whipped topping (or whipped cream)
- ¼ cup mini chocolate chips (optional)
- Chopped peanut butter cups (optional)
- Chocolate drizzle (optional)
Step-by-Step Instructions
Step 1: Make the crust
- Crush the Oreos into fine crumbs (food processor or zip bag + rolling pin).
- Mix crumbs with melted butter until the texture looks like wet sand.
- Press firmly into the bottom of an 8×8-inch pan (line with parchment if you want easy lifting).
- Chill the crust while you make the next layer (10 minutes).
Step 2: Make the peanut butter layer
- In a bowl, beat the cream cheese until smooth (no lumps).
- Add peanut butter, powdered sugar, and vanilla. Beat until creamy and thick.
- Fold in whipped topping gently to keep it light and fluffy.
- Spread evenly over the chilled crust.
Step 3: Add the chocolate pudding layer
- Whisk instant pudding mix with cold milk for 2 minutes, until it thickens.
- Let it sit for 3–5 minutes so it firms up.
- Spread pudding over the peanut butter layer carefully.
Step 4: Top and chill
- Spread the final layer of whipped topping on top.
- Add toppings (chocolate chips, chopped peanut butter cups, drizzle—your choice).
- Cover and refrigerate at least 4 hours, preferably overnight, for clean slices.
Step 5: Slice and serve
- Lift out using parchment (optional), slice into squares, and serve cold.

Tips for Perfect Layers
- Use softened cream cheese so the peanut butter layer stays silky.
- Fold the whipped topping in gently (don’t overmix).
- For neat slices, chill overnight and wipe the knife between cuts.
Storage
- Fridge: 3–4 days, covered.
- Freezer: up to 1 month (slice first, wrap individually). Thaw in the fridge.
Easy Variations
- Nutter Butter crust: swap Oreos for Nutter Butter cookies.
- Extra chocolate: add a thin layer of chocolate ganache between pudding and topping.
- More crunch: sprinkle chopped peanuts between layers.
