Peanut Butter Chocolate Bars

If you like chocolate (who doesn’t?) and if you like peanut butter (ok, some people might not), then you’ll love these peanut butter chocolate bars! A friend made them for a 4th of July party, and everyone at the party asked for the recipe. So, now it my turn to share it with you.

Peanut Butter Chocolate Bars



  • 1 box yellow cake mix (no pudding)
  • 1 cup chunky peanut butter
  • 1 stick butter
  • 2 eggs 


  • 1 12 ounce package chocolate chips
  • 1 can sweetened condensed milk
  • 2 Tbsp. butter
  • 1 tsp. vanilla 
  • 1 1/2 cups unsalted peanuts, chopped 


  1. Preheat oven to 325 degrees. Line a 9×13 baking pan with foil (leave some hanging over the edges, making handles) and spray with Pam.
  2. For the crust: melt butter. On a low speed, mix cake mix, peanut butter, melted butter and eggs for 1 minute.
  3. Set aside 1 1/2 cups of the mix for the top.
  4. Pour remaining mix in pan and push down with finger to make bottom layer.
  5. For the filling: melt chocolate chips, butter and milk either in the microwave or on the stove using a double boiler. Stir frequently to make sure it doesn’t burn. Stir in vanilla.
  6. Pour over crust. Top chocolate layer with remaining crust mix, crumbled. Top with chopped peanuts. (Note: 1 1/2 cups might be too much. You might be able to get away with 1 cup.)
  7. Bake 30-35 minutes. Let cool. Cut and serve. (After cutting, bars can be refrigerated to set the chocolate.)

  2. Hi Mike,
    I actually debated a long time in the store, and finally went with semi-sweet chocolate chips. I thought they’d stand up better to the DC heat. I used Tollhouse, which is just my preference from growing up.

  3. What kind of chocolate chips were used in your recipe? Semi-sweet or milk chocolate? ( And brand if you know off the top of your head since Hershey and Tollhouse taste totally different )
