Ingredients
- 20 pieces chocolate wafer cookies
- 1 cup creamy peanut butter
- 1/2 cup powdered sugar
- 2 cups heavy whipping cream
- 1 tsp vanilla extract
- 1/4 cup milk
Instructions

- Step 3: Gently fold half of the whipped cream into the peanut butter mixture until fully combined and fluffy.
- Step 4: Spread a thin layer of peanut butter mousse on the bottom of an 8x8 inch dish. Arrange 5 chocolate wafer cookies side by side over the mousse.

- Step 7: Cover and refrigerate the cake for at least 6 hours or overnight to allow the wafers to soften and flavors to meld.

Can I substitute ingredients in No-Bake Chocolate Peanut Butter Icebox Cake?
