Ingredients

  • 1 8-ounce package cream cheese softened
  • 1/3 cup creamy peanut butter
  • 2-1/2 cups freshly whipped cream** or can use your favorite whipped topping like Cool Whip
  • 16-20 thin & crispy oatmeal cookies not soft & chewy (I used a generic store brand; see notes)
  • 2/3 cup mini M&M's
  • 1/3 cup mini semisweet chocolate chips

Optional Toppings:

  • 3 monster oatmeal cookies
  • any type of M&M's I used a mix of mini and peanut butter M&M's
  • oatmeal cookie crumbs
  • powdered sugar
  • chocolate sauce

Instructions

  1. **To make the freshly whipped cream, beat 1-1/4 cups cold heavy cream with 1/4 cup powdered sugar until stiff peaks form. Set aside.

  2. In the bowl of a stand mixer or using a hand mixer, combine the cream cheese and peanut butter until creamy. Add freshly whipped cream or Cool Whip and beat until smooth.

  3. Arrange oatmeal cookies evenly in the bottom of a 6 inch or 8-inch springform pan covering as much of the bottom as possible. Break up a cookie or two to fill in any gaps (it's okay if it's not perfect). Spread 1/3 of the peanut butter cream cheese layer evenly over the cookies and top with 2 tablespoons of M&M's and chocolate chips.
  4. Repeat layers two more times ending with the cream layer, smoothing out evenly. Garnish with more M&M's, chocolate chips and oatmeal cookie crumbs.
  5. Cover and refrigerate for 5-6 hours or overnight until the oatmeal cookies have softened. Pipe a few rosettes with reserved cheesecake mixture, then drizzle with chocolate sauce and add a sprinkle of powdered sugar, if desired. Serve chilled.

Recipe Notes

*Thin hard oatmeal cookies work best (I used a generic store brand) but feel free to use your favorite brand. Avoid the soft and chewy brands like Pepperidge Farms or Mrs. Fields, as they might not hold up as well.
