Peanut Butter Fudgy M&M Bars

Teresa Ambra
Rich and decadent, this sensational dessert bar starts with a cake mix and crunchy peanut butter for the base. Then it's topped with dark chocolate fudge frosting mixed with more crunchy peanut butter. Finally the frosting is covered with M&Ms and chopped peanuts. It's fabulous for potlucks, tailgating parties or summer holiday fun like Memorial Day, Fourth of July or Labor Day.

  • measuring spoons
  • 1 small mixing bowl
  • 1 sharp knife to chop peanuts if they're not pre-chopped
  • 1 spatula
  • 1 nut chopper if nuts are not previously chopped

Ingredients
  

  • 18.25 oz. pkg. Golden Butter recipe cake mix
  • 1 cup crunchy peanut butter
  • 1/3 cup water
  • 1 large egg
  • 16 oz. can dark chocolate fudge frosting
  • 1/2 cup crunchy peanut butter
  • 1 cup M&Ms
  • 1/2 cup peanuts chopped (measure after chopping)

Instructions
 

  • Heat oven to 350°.
  • Grease or spray a 9x13” glass baking dish.
  • In large mixing bowl, combine cake mix, 1 cup crunchy peanut butter, water and egg and mix until well combined.
  • Spread into bottom of prepared baking dish.
  • Smooth the top really well.
  • Bake at 350° for 20-25 minutes or until puffy and golden brown or a toothpick inserted in center comes out clean.
  • Cool completely.
  • In a small mixing bowl blend chocolate fudge frosting with ½ cup crunchy peanut butter.
  • Spread over top of the cooled bars.
  • Sprinkle with chopped peanuts, then M&Ms.
  • Gently press the peanuts and M&Ms into the icing.

Notes

NOTE: I recommend refrigerating or freezing the bars before cutting, so the icing is not quite so goopy.
 
NOTE: If your cake mix is not 18.25 ounces, you may need to add a couple of ounces of flour to bring it up to that amount. Otherwise, the brownies will not have the same texture.
