Peanut Butter Brownies w/ Peanut Butter Cup Frosting


Peanut Butter Brownies w/ Peanut Butter Cup Frosting

Who watched the Wisconsin vs Kentucky basketball game on Saturday night?  Such a tough loss for the Badgers.  They played so well, and then lost by 1 point in the final seconds of the game.  Only the 3rd time in school history that they have made it this far,  so no matter what, it was a great season!  I just wish it could have ended differently.  My 8 year old had 2 more football games this weekend.  It was a tough 2 games as well!  The first game was a tie, and the 2nd game they lost by just 1 touchdown.  So much stress for a weekend!

To ease into the work week, how about we start with some over the top peanut butter brownies.  These are pretty much the definition of indulgent.  They start as a rich and fudgy brownie.  Chopped peanut butter cups are then folded in.  Once they are baked and cooled, the brownies are topped with a frosting that is made from even more peanut butter cups.  Yep, you read that right.  Actual peanut butter cups are ground up, and used to flavor the frosting.  I may or may not have eaten the frosting with a spoon.  If you are a fan of peanut butter and chocolate together, these are pretty much heaven!

I made these peanut butter brownies when we had friends visiting.  After dinner the kids went to go play.  We told them they could come back for dessert a little later.  We decided to enjoy dessert while they were off playing.  They were so good, when the kids came back we told them it was too late, and they needed to get ready for bed.  There was not a whole lot of sharing going on!

  • 3/4 cup butter, melted
  • 3/4 cup cocoa powder

  • 1/2 tsp salt
  • 1 cup peanut butter cups, chopped
  • Frosting
  • 1/2 cup butter, softened
  • 1/4 cocoa powder
  • 2 tsp vanilla
  • 2-3 cups powdered sugar
  • 1/4 cup milk
  • 1 cup peanut butter cups, crushed

  4. Sounds delicious! Wonderful inviting photos:)

  5. Oh my, these look SO good! Pinned!

  6. I generally avoid ‘strange’ brownies, because they are so often dry. I don’t want to waste
    calories on a dry brownie. These brownies are definitely NOT dry. In fact they are delectably gooey—and that is a BIG compliment.

  7. I would have a hard time sharing these! So good!

  8. Gorgeous treat.. I am sure it tasted amazing!
