  • 1 16.3-ounce jar creamy peanut butter (1 3/4 cups)
  • 1 16-ounce tub vanilla frosting (Betty Crocker or Aldi store brand)


  • Line a 8x8 or 9x9 baking pan or dish with aluminum foil or parchment paper for easy lifting out of pan to slice.
  • Stir together peanut butter and frosting in a large microwave-safe glass bowl.
  • Microwave on HIGH 1 minute and stir until smooth. (1200 watts). Pour the peanut butter mixture into the pan, spreading to the edges with a knife or spatula.
  • Chill, uncovered, at least 1 hours or until firm. Once firm, the fudge can be cut into bite-size pieces or slabs.
  • Store in an airtight container at room temperature or in the refrigerator.


Note: Not all tub frostings are the same. Duncan Hines did not have as smooth a texture as Betty Crocker and Aldi because of the water content. Do NOT use “whipped” tub frosting.
