Step-by-Step Instructions

Step 1 — Prepare the Dish

Lightly grease the bottom of your dish or line it with parchment for cleaner serving.

Step 2 — Base Cookie Layer

Pour milk into a shallow bowl. Dip each peanut butter cookie quickly into the milk, just long enough to soften the exterior. Arrange them in a full even layer at the bottom of your dish. The cookies should fit snugly without major gaps.

Step 3 — Mix the Peanut Butter Cheesecake Layer

In a medium mixing bowl, beat the softened cream cheese until smooth and free of lumps. Add the peanut butter and powdered sugar, continuing to mix until completely combined. Add the vanilla extract.
Finally, fold in the whipped topping gently to maintain a light, fluffy consistency.

Spread half of this peanut butter cheesecake mixture evenly across the cookie layer.

Step 4 — Second Cookie Layer

Dip additional cookies into the milk and create a second cookie layer on top of the filling.

Step 5 — Remaining Peanut Butter Filling

Spread the remaining peanut butter cheesecake mixture across the second cookie layer. Smooth with a spatula to keep the layers neat.

Step 6 — Chocolate Ganache Layer

Heat the heavy cream in a microwave-safe bowl for about 45–60 seconds, until hot but not boiling.
Add the chocolate chips and allow them to sit for 1 minute to soften. Stir until the mixture becomes silky and fully melted.

Allow the ganache to cool slightly for a few minutes before pouring it across the top filling layer. Spread carefully to avoid disrupting the layers underneath.

Step 7 — Whipped Topping Layer

Add the final whipped topping layer across the chocolate, smoothing the surface.

Step 8 — Chill

Cover the dessert with plastic wrap and refrigerate for at least 4 hours. Overnight chilling is ideal and allows the cookies to soften into a cake-like texture.

Step 9 — Garnish

Right before serving, decorate with cookie crumbs, chopped peanut butter cups, or a drizzle of melted peanut butter or chocolate.

Serving and Presentation

Use a sharp knife to cut into neat slices. Wipe the knife clean between cuts for clean layers. Serve chilled and enjoy the combination of creamy filling, rich chocolate, and softened cookie layers.

Storage Instructions

Freezing individual servings is a great option for long-lasting treats.

Helpful Tips

• Dip the cookies very briefly so they soften without falling apart.

• Full-fat cream cheese gives the smoothest result.

• For extra clean slices, freeze the dessert for 15–25 minutes before serving.

• Keep the whipped topping chilled until using to maintain structure.

• Let each layer spread fully to the edges for even coverage.

Variations

This concept allows endless creativity, and seasonal themes can be added easily.

Can I make this a day ahead?
Yes. In fact, the texture and flavors improve significantly after sitting overnight.

Can I use homemade peanut butter cookies?
Yes, but make sure they are firm enough to hold shape when lightly soaked in milk.
