Peanut Butter Oreo Icebox Cake Recipe

Today I’m sharing this easy peanut butter Oreo icebox cake. It’s basically a homemade peanut butter ice cream cake that’s smooth, creamy and stuffed with layers of Oreo cookies. And best of all – it takes under 15 minutes to prepare.

Ps – it’s Fiona from Just So Tasty stopping in. This summer, icebox cakes have been my go-to dessert. They’re so easy to make, completely no bake, and no one can turn down a slice.

Whether it’s a Classic Icebox Cake, lemon icebox cake or s’mores icecream cake – no bake desserts are perfect for summer. And since peanut butter is probably my favorite thing on earth – it was definitely time to make this peanut butter Oreo icebox cake.

It has layers of creamy peanut butter filling, alternating with layers of Oreo cookies. It basically tastes in between a peanut butter cheesecake and a peanut butter ice cream cake – which is a very good thing.

For this peanut butter icebox cake – we’re making it in a loaf pan. I used an 8 inch loaf pan, but a 9 inch pan will work just fine too.

The peanut butter filling is super easy and only needs 4 ingredients:

  • whipping cream
  • cream cheese
  • peanut butter
  • powdered sugar

How to Make Peanut Butter Oreo Icebox Cake

  1. First beat the whipping cream until stiff peaks form. If you prefer whipped topping (such as cool whip) feel free to use it instead.
  2. Then in a separate bowl beat together the cream cheese, peanut butter and powdered sugar.
  3. Last but not least, mix the whipped cream into the peanut butter mixture.

From there, it’s time to assemble. Line the loaf pan with 2 sheets of parchment paper (or aluminum foil) so that there’s an overhang on each side. Then alternated between adding a layer of Oreo cookies with a layer of peanut butter filling.

Feel free to use whatever variety of Oreos is your favorite – plain, peanut butter or double stuffed work perfectly. Before adding each Oreo cookie, it gets dipped in a little milk first to soften the cookies. This step is super important so that you can easily slice the cake.

Then it goes in the freezer to harden for about 4 hours (or more). You can also let it set in the fridge if you prefer a softer consistency, instead of a consistency that’s more like ice cream.

Then for the toppings!!!! You can either add the toppings right before serving, or do it ahead of time. I like to add crushed Oreos, peanuts & chocolate sauce. But it’s totally up to you. Peanut butter cups, Reese’s Pieces, or chocolate chips are also delicious options.

This peanut butter Oreo icebox cake is such a delicious treat for summer, or whenever you’re looking for an easy no bake peanut butter treat. With peanut butter, whipped cream, Oreo cookies and chocolate sauce – you really can’t go wrong!

  1. Greetings Pinky Girl 🙋‍♀ that was the name of my very 1st puppy!)
    If I wanted just the peanut butter icebox cake, are there anything different I need to do? I love peanut butter and would like to just have it ALL peanut butter. Thanks!

    1. I haven’t made it without the cookies (or some type of cookie) before. But I can’t see why it wouldn’t work!

  2. 5 stars
