Nutter Butter Peanut Butter Cake Recipe

If you’re crazy about peanut butter like my family is, try this semi-homemade nutter butter peanut butter cake! We took a box cake mix and jazzed it up with a little peanut butter to give it that sweet, rich flavor of peanut butter that people go crazy for.

It’s topped with our favorite peanut butter buttercream, an easy, homemade frosting that tastes like the inside of a Reese’s cup!

Peanut Butter Cake

This cake starts with a box cake mix which makes it semi-homemade and really easy! It has just a light peanut butter flavor. We bake the cake in 2 9″ round baking pans, but you can also simply make this in a 9×13 baking pan if you’d like a sheet cake.

If you’re baking round cakes, allow them to cool in the pan for 10 minutes, then turn them out onto a wire rack to cool completely.

Peanut Butter Frosting

This frosting is AMAZING. Not only does it taste like Nutter Butter cookie filling, it also could easily pass as a buckeye, my favorite homemade candy! Just try not to eat this frosting with a spoon. It’s that good.

I haven’t ever tried this frosting with natural peanut butter and I’m not sure it would work. We use traditional creamy peanut butter. Be sure to add your milk 1 tablespoon at a time until your frosting is at a good spreadable consistency. All peanut butters are different so you may not need as much milk.

Decorate the Cake

We used Wilton Tip 1M to pipe pretty swirls on this layer cake, then topped it with Nutter Butter cookies.

It’s guaranteed to bring out the kid in you!
