116-ounce tub vanilla frosting (Betty Crocker or Aldi store brand)
Instructions
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.
Notes
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.
