Peanut Butter Mississippi Mud Brownies

Mississippi Mud Peanut Butter Brownies

Chocolate and peanut butter is maybe my favorite flavor combination ever. (Original I know.) But who doesn’t love it?

I almost feel like adding another ingredient to the mix is like adding a third wheel and upsetting the dynamics of a perfect union. But these Peanut Butter Mississippi Mud Brownies are incredibly rich and gooey, and a layer of marshmallows fits right in without detracting from the delicious flavors of the chocolate and peanut butter.

The creaminess of the peanut butter definitely takes these brownies over the edge and I think I like this recipe even more than the Mississippi Mud Cupcakes I made several weeks ago. But maybe not quite as much as Mississippi Mud Pie. That one is hard to beat!

  6. Combine peanut butter and canola oil in a small bowl and microwave for 10 seconds on HIGH. Stir to combine and drizzle on top of marshmallow covered brownies.
  7. For chocolate frosting, combine ¼ butter, unsweetened cocoa, and milk in a saucepan and cook over medium heat, stirring constantly for 2-3 minutes.. Whisk in powdered sugar and vanilla extract until smooth. Drizzle on top of brownies.
