How To Make Reese’s Peanut Butter Chocolate Icebox Cake

Note: This is a summary of the steps. For the full instructions, see the recipe card below.

STEP 1: Prepare a 9-inch spring form pan. Line the sides with parchment paper that sticks about an inch above the sides of the pan. This will help you lift the cake out later. Set the pan aside.
STEP 2: Make the mousse base by following the instructions listed in the recipe card. Divide the mousse between two bowls. You will want twice the amount in one bowl as the other. You should have 2 1/3 cups in one bowl and the rest in the other.
STEP 3: Add the peanut butter to the bowl with the more significant mousse. Fold it in to combine.
Add the cocoa to the smaller amount and fold it in to combine.
STEP 4: Start assembling the icebox cake. Place a single layer of cookies dunked in milk in the bottom of the prepared pan. Spread half of the peanut butter mousse on top.
STEP 5: Add a layer of dunked cookies on top of the peanut butter mousse. Spread them with the chocolate mousse.
STEP 6: Add a layer of dunked cookies to the chocolate mousse layer. Spread the cookies with the remaining peanut butter mousse.
STEP 7: Refrigerate the icebox cake for at least 4-5 hours, preferably overnight.
STEP 8: Once firm, lift the icebox cake from the pan. Use the overlapped parchment paper to carefully lift out the cake.
STEP 9: Make the chocolate whipped topping. Add it to a piping bag. Decorate the top of the cake. Drizzle on the chocolate sauce and garnish with the chopped mini Reese’s cups. Refrigerate until ready to slice and serve.

What Is An Icebox Cake?

An icebox cake is typically a no-bake dessert that includes layered ingredients that form a cake. The ingredients of an icebox cake will contain some that should be refrigerated. These include ice cream, cream cheese, sour cream, whipped cream, pudding, jello, fruit, and more. The refrigeration process keeps the ingredients fresh and helps the cake set and form.

Why Do I Need To Dunk The Cookies In Milk?

Dunking the peanut butter Oreo’s in milk will help soften the cookies. This will make them easy to cut into and eat once the icebox cake is ready to serve.

Ingredient Variations

  • You can swap out the Oreo peanut butter cookies for Nutter Butter cookies.
  • Add the chopped Reese’s peanut butter cups. Then garnish the top with either chocolate shavings, crumbled Oreo’s, or finely chopped peanuts.
  • Instead of drizzling with chocolate syrup, drizzle with warmed peanut butter you’ve microwaved.

How Do I Assemble The Icebox Cake?

There are three layers that you will assemble. Here’s how:

  1. Layer the milk-dunked Oreo’s in the bottom of the prepared pan. Spread half of the peanut butter mousse mixture over the top.
  2. Add another layer of the milk-dunked Oreo’s on top of that and spread them with the chocolate mousse.
  3. Add the third layer of milk-dunked Oreo’s on top of the chocolate mousse. Spread the Oreo’s with the remaining peanut butter mousse.
  4. Refrigerate the cake until firm, at least 4-5 hours or overnight.
  5. Once firm, remove the icebox cake from the pan. Decorate the top with the chocolate whipped cream topping, drizzled chocolate sauce,, and chopped mini Reese’s cups. Refrigerate until ready to slice and serve.

Variation For Serving

  • Rectangular Pan: You can make this icebox cake in a deep 9 x 13 baking dish. Using a spring form pan is not necessary. You don’t need to worry about removing it from the dish. This is an excellent idea if you’re taking it to a potluck.
  • Loaf Pans: This recipe will make enough to fill 2 loaf pans. Be sure to line the loaf pans with parchment paper with overhang. This way, you can easily lift the cake out once it’s chilled and set. This is an excellent idea if you want to serve one cake now and freeze one for later.

Storage

Store, covered, in the refrigerator for 3-4 days. To freeze, cover tightly in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before serving.
