Ingredients
1. 1 can (16 ounces) vanilla frosting
The vanilla frosting provides the sweetness and creamy foundation for this shortcut fudge. Because it is already smooth and prepared, it eliminates the need for powdered sugar, butter, milk, or a traditional cooked fudge base. When warmed gently, it blends easily with the peanut butter.
2. 1 cup creamy peanut butter
The creamy peanut butter supplies the star flavor and gives the fudge its rich, nutty character. Choose a smooth peanut butter for the most uniform texture and easiest mixing.
How to Make 2-Ingredient Peanut Butter Fudge
Step 1: Prepare the pan
Lightly grease a small glass or ceramic baking dish. For especially easy removal, line the dish with parchment paper, leaving a little overhang on the sides so you can lift the chilled fudge out later.
Step 2: Combine the ingredients
Add the vanilla frosting and creamy peanut butter to a medium microwave-safe bowl.
Step 3: Microwave gently
Microwave the mixture in 30-second intervals, stirring thoroughly after each interval. Continue until the frosting and peanut butter are smooth and completely combined.
Do not overheat the mixture. You only need enough gentle heat to make everything soft and blendable.
Step 4: Spread into the pan
Pour the warm peanut butter mixture into your prepared baking dish. Use a spatula to spread it into an even layer, smoothing the surface.
Step 5: Chill until firm
Refrigerate for 2 to 3 hours, or until the fudge is firm enough to slice cleanly.
Step 6: Slice and serve
Lift the fudge from the pan if using parchment, then cut it into small squares with a sharp knife. Serve chilled or allow it to sit at room temperature briefly for a softer, creamier bite.
Pro Tips for Perfect Peanut Butter Fudge
Use parchment for easy removal. Lining the dish makes it much easier to lift the entire slab out before cutting.
Heat in short intervals. Microwaves vary, so avoid heating the mixture for too long at once. 30-second intervals give you better control and help prevent overheating.
Stir thoroughly between intervals. The mixture may look only partly melted at first, but vigorous stirring can help distribute the warmth and create a smooth consistency.
Chill completely before slicing. If the fudge seems soft, give it additional refrigerator time. A thoroughly chilled slab produces much cleaner squares.
Clean your knife between cuts. For those neat, bakery-style pieces, wipe the knife with a clean cloth or paper towel after each slice.
Adjust the serving texture. Keep the fudge chilled for a firm, candy-shop-style bite. Let individual pieces sit at room temperature for several minutes if you prefer them softer.
Easy Variations
The beauty of this 2-ingredient peanut butter fudge recipe is that the basic version is delicious all by itself, but it also gives you plenty of room to add your own touch.
– Salted Peanut Butter Fudge: Sprinkle a little flaky salt over the top before chilling.
– Crunchy Peanut Fudge: Stir in a small handful of chopped salted peanuts.
– Chocolate-Peanut Butter Fudge: Add a light drizzle of melted chocolate over the chilled fudge.
– Holiday Fudge: Decorate the top with festive sprinkles before refrigerating.
– Peanut Butter Pretzel Fudge: Add crushed pretzels for a salty, crunchy contrast.
How to Serve Peanut Butter Fudge
Cut the fudge into small squares and arrange it on a dessert platter for an easy party treat. The rich sweetness pairs especially well with hot coffee, black tea, or a cold glass of milk.
For a larger dessert spread, serve the fudge alongside chocolate-covered nuts, salted pretzels, fresh strawberries, cookies, or other bite-sized sweets. The salty and fruity accompaniments provide a nice contrast to the creamy sweetness.
This fudge is also an excellent addition to holiday cookie trays and homemade gift boxes. Pack the chilled squares in a small lined container and separate layers with parchment paper.
