Peanut Butter Cup Cake Ingredients

For the Cake:

  • Chocolate Cake Mix: We’re going to make it taste homemade with the ingredients listed below.
  • Milk: I used whole milk. It will make the cake super moist.
  • Eggs
  • Butter: Adds a wonderful richness oil just can’t provide.

For the Easy Peanut Butter Buttercream:

  • Butter
  • Peanut Butter: Duh!
  • Powdered Sugar
  • Heavy Cream
  • Vanilla
  • Salt: A pinch of salt helps balance out the sweetness.

For the Chocolate Ganache: Ganache is a chocolate glaze that can be used as a filling or a frosting. While it sounds complicated, ganache only requires two ingredients: chocolate and cream. When these ingredients are combined over low heat, it creates a shiny chocolate glaze that can poured. As it cools, it thickens. It can be used for many types of desserts, including this Reese’s Peanut Butter Cup Cake.

  • Chocolate Chips
  • Heavy Cream


  • Chocolate Shavings: Great tutorial on this here.

Frequently Asked Questions

1. How to Store Reese’s Peanut Butter Cup Cake

This Reese’s cake recipe, is best stored in the fridge. Storing in the fridge will keep the ganache from melting. No need to worry about the cake drying out, the buttercream will keep in the moisture. An easy way to store the cake is in a cake stand with a lid. Any container with a lid or even a plate tightly wrapped with foil will also work.

2. Can you Freeze It?

Yes this keep freezes well. In order to freeze the Reese’s Peanut Butter Cake, you will want to put it in the freezer first, uncovered for about 30 minutes. This freezes the frosting and ganache and prevents it from sticking to the plastic wrap or container. Once frozen, make sure the cake is wrapped well to prevent air from getting to it. This will prevent freezer burn. The cake will stay fresh in the freezer for up to 3 months.

3. How Do You Get Smooth Frosting?

In order to get smooth frosting, you need to make sure the butter is softened. Start by using your mixer and mixing the butter and peanut butter until it is light and airy. When you add the sugar and liquids, you want to add it in slowly, giving it time to become completely incorporated. This prevents lumps from forming. When icing the cake itself I like to use an offset spatula and a revolving cake stand. Spin and scoop off extra frosting until you have a thin even layer.
