A creamy, crunchy, no-bake peanut butter dessert layered like a lasagna, perfect for parties and potlucks. It combines a crunchy cookie base with rich peanut butter, cream cheese, and whipped topping layers.

Ingredients

Scale
  • 1 package chocolate sandwich cookies (about 36 cookies), crushed (Oreo recommended)
  • 6 tablespoons unsalted butter, melted
  • 1 cup creamy peanut butter (smooth)
  • 8 oz cream cheese, softened
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 2 cups heavy whipping cream, chilled (or 2 tubs whipped topping)
  • 1/4 cup powdered sugar (if making fresh whipped cream)
  • 1 teaspoon vanilla extract (if making fresh whipped cream)
  • Chocolate shavings or mini chocolate chips (optional garnish)
  • Chopped peanuts (optional garnish)

Instructions

  1. Crush chocolate sandwich cookies finely using a food processor or place in a sealed plastic bag and crush with a rolling pin.
  2. Mix crushed cookies with 6 tablespoons melted butter until mixture resembles wet sand.
  3. Press mixture firmly and evenly into the bottom of a 9×13 inch baking dish. Chill in refrigerator for about 10 minutes.
  4. In a medium bowl, combine softened cream cheese and creamy peanut butter. Beat with electric mixer on medium speed until smooth and creamy (2-3 minutes).
  5. Add powdered sugar and vanilla extract, beat again until well combined and fluffy.
  6. Spread peanut butter mixture evenly over chilled cookie base. Return to fridge for about 15 minutes to set slightly.
  7. If making fresh whipped cream, chill mixing bowl and beaters for 15 minutes. Pour heavy whipping cream into bowl, add powdered sugar and vanilla extract, whip on medium-high speed until stiff peaks form (5-7 minutes). If using store-bought whipped topping, thaw as per package instructions.
  8. Spread half of the whipped cream evenly over peanut butter layer.
  9. Optionally, sprinkle a thin, even layer of crushed cookies over the whipped cream for extra texture.
  10. Top with remaining whipped cream, spreading evenly to seal layers.
  11. Cover dish tightly with plastic wrap and refrigerate for at least 4 hours or overnight.
  12. Before serving, garnish with chocolate shavings or mini chocolate chips and chopped peanuts.

Notes

Use a gentle hand when spreading layers to keep them neat. Let cream cheese soften before mixing to avoid lumps. Chill dessert well for clean slicing. Let dessert sit at room temperature for 5-10 minutes before serving to enhance flavors. For gluten-free, use gluten-free cookies; for vegan, use dairy-free cream cheese and whipped topping alternatives.
