Recipe Tips

  • Combine Ingredients – Combine the cake batter ingredients with a electric mixer or a stand mixer. Make sure to not overmix the batter as this could change the texture of the cake.
  • Cool Cake – Allow cakes to cool on a cooling rack before frosting. We like to make the cakes ahead of time so they are completely cooled.
  • Frosting the Cake – We recommend following the frosting cake steps as they are written. This ensures that the creamy peanut butter frosting stays on the cake.
  • Topping the Cake – We love the additional chocolate ganache that we frost the cake with. Piping the peanut butter frosting adds flavor and make is look so complete.

How to Store Leftovers

I kept mine in the fridge since it was a little warm in our house, but I don’t think it is necessary. This cake can be stored at room temperature in an air tight container for 3-4 days or covered with plastic wrap. Our family loved it and I loved that I didn’t have to do much work to have a fun dessert on the table that the entire family love!
