Peanut Butter Cup Buttercream

Peanut butter cup buttercream. I don’t know if there is anything more that I need to say about this frosting recipe other than it’s one of the best peanut butter recipes ever.

Peanut Butter Cup Buttercream! This is the best buttercream frosting recipe. Delicious on chocolate cupcakes.

I first created this frosting back in August when I made up the PMS Buster Cupcakes recipe (chocolate cupcakes, filled with a peanut butter chocolate pudding topped with this frosting). It tastes so amazing, just try not to eat it out of the bowl with a spoon – the scale doesn’t look too kindly to that the next day (don’t ask me how I know).

      AH! I know it’s driving me nuts. All of my images are optimized. I’m trying to figure it out. I had the cache plugin and it helped but it messed up the blog in a different way.
