The quickest, creamiest fudge you’ll ever make—just peanut butter + frosting, zero baking, minimal cleanup, and ready in under 5 minutes of active prep.
Ingredients
-
1 (16 oz) jar creamy peanut butter – smooth and sweetened (avoid natural/separated varieties if possible)
-
1 (16 oz) can vanilla frosting – any common brand like Betty Crocker or Pillsbury
Optional Toppings:
-
Flaky sea salt
-
Whole roasted peanuts
-
Chocolate chips, crushed cookies, or pretzels
Instructions
1. Prep Your Pan
-
Line an 8×8 or 9×9-inch baking pan with parchment paper, leaving extra overhang for easy lifting later.
2. Melt the Frosting
-
Scoop frosting into a microwave-safe bowl.
-
Microwave on high for 60 seconds. Stir, then heat in 15-second bursts until pourable but not boiling.
3. Combine with Peanut Butter
-
Place peanut butter in a large mixing bowl.
-
Pour melted frosting over the peanut butter.
-
Stir vigorously until fully smooth and homogenous.
4. Spread in Pan
-
Pour mixture into prepared pan.
-
Smooth evenly with a spatula (dip spatula in warm water for a glossy finish).
5. Chill
-
Let fudge set at room temperature ~1 hour or refrigerate 15–30 minutes until firm.
6. Slice & Serve
-
Lift fudge using parchment paper overhang.
-
Slice into small squares (~6×6 grid).
-
Optional: sprinkle toppings or press in whole peanuts.
Notes

Use a dry bowl and utensils to prevent sticking or seizing.

Natural peanut butter may need extra chilling to firm up.
