Ingredients

Here’s what you’ll need for this simple yet irresistible dessert:

• 1 container (8 oz) Cool Whip, thawed
• 1 cup (260g) creamy peanut butter
• 1½ cups (190g) chopped Reese’s Peanut Butter Cups
• 24 chocolate sandwich cookies

Ingredient Tips & Substitutions

• Cool Whip: If you prefer homemade, substitute with stabilized whipped cream.
• Peanut Butter: Use natural peanut butter for a less sweet, more intense peanut flavor.
• Reese’s Peanut Butter Cups: Mini cups work well for easier chopping.
• Cookies: Swap chocolate sandwich cookies with gluten-free or vegan alternatives if needed.

Step-by-Step Instructions

1. Line an 8×8-inch baking dish with parchment paper for easy removal.
2. Spread a thin layer of Cool Whip on the bottom of the dish to anchor the first cookie layer.
3. Arrange a single layer of chocolate sandwich cookies over the Cool Whip, breaking cookies to fit if necessary.
4. In a medium bowl, mix peanut butter with the remaining Cool Whip until smooth and fluffy.
5. Gently fold in the chopped Reese’s Peanut Butter Cups.
6. Spread half of the peanut butter mixture over the cookie layer.
7. Repeat with another layer of cookies and the remaining peanut butter mixture.
8. Cover and refrigerate for at least 6 hours, though overnight chilling is ideal for the best texture.

Tip: Letting the cake chill overnight allows the cookies to soften fully, creating a cake-like consistency.
