It is also a great last-minute dessert because the preparation takes only a few minutes.
Ingredients
- 1 cup creamy peanut butter
- 1 can vanilla frosting
How to Make 2-Ingredient Peanut Butter Fudge
Step 1: Prepare the Pan
Line an 8-inch square baking pan with parchment paper or wax paper.
Leave a little overhang on two sides so the finished fudge can easily be lifted from the pan.
Step 2: Melt the Ingredients
Place the peanut butter and vanilla frosting in a microwave-safe bowl.
Microwave for approximately 30 seconds.
Stir thoroughly, then continue heating in short 15- to 20-second intervals until the mixture is smooth and completely combined.
Do not overheat the mixture.
Step 3: Pour Into the Pan
Immediately transfer the mixture to the prepared pan.
Spread it evenly with a spatula.
Work fairly quickly because the fudge mixture will begin to thicken as it cools.
Step 4: Chill
Refrigerate for at least 1 to 2 hours, or until the fudge is firm.
For the cleanest cuts, allow it to chill completely.
Step 5: Cut and Serve
Use the parchment paper to lift the fudge from the pan.
Place it on a cutting board and cut into small squares.
Serve chilled or allow the pieces to sit at room temperature for a few minutes before serving.
Tips for the Best Peanut Butter Fudge
Use creamy peanut butter for the smoothest texture.
Regular commercial peanut butter generally works best because natural peanut butter can separate and produce a softer or oily fudge.
Avoid overheating the frosting and peanut butter. Short bursts in the microwave make it easier to achieve a smooth consistency.
Line the pan with parchment paper so you can easily remove the entire slab of fudge.
Use a sharp knife for clean cuts. Wiping the knife between cuts can help keep the squares neat.
Easy Variations
Although this fudge is delicious with only two ingredients, you can add optional toppings or mix-ins if desired.
Stir in chopped peanuts for extra crunch.
Add mini chocolate chips after the mixture has cooled slightly.
Drizzle the finished fudge with melted chocolate.
Sprinkle a small amount of flaky sea salt over the top before chilling for a sweet-and-salty combination.
For extra peanut butter flavor, swirl a spoonful of melted peanut butter across the top before refrigerating.
When to Serve Peanut Butter Fudge
This simple fudge is perfect for Christmas cookie trays, holiday parties, bake sales, potlucks, birthday celebrations, and homemade food gifts.

Storage

Thaw frozen fudge in the refrigerator before serving.
