Peanut Butter Cup Cake Recipe

This Spring we didn’t get to celebrate Aaron’s birthday on time because he was supposed to be out of town for work. We decided to celebrate his birthday and Ron’s together in April. This joint party meant I either had to make 2 cakes or find one that would make them both happy, this Peanut Butter Cup Cake did just that!

As I was dreaming up this cake, I decided it should be a 2 layer round chocolate cake with peanut butter cream cheese frosting with peanut butter cups between the layers and on top. As this plan was coming together, I hopped on Amazon and ordered a cake leveler, which was delayed and didn’t arrive in time for this cake, but I used it on my birthday cake and I am in love! When I went to the store I found the Betty Crocker Triple Chocolate Cake Mix and decided to try that, it was amazing! I also used a bout a half of a bag of mini Reece’s Peanut Butter Cups in this recipe.
