Why This Recipe Works
Peanut butter fudge relies on the natural fats and proteins in peanut butter combined with the sweetness and structure of its second ingredient. When mixed together and chilled, the ingredients firm up into a smooth, sliceable fudge with a melt-in-your-mouth texture. It’s a foolproof method that doesn’t require special skills or equipment.
Ingredients You’ll Need
-
1 cup creamy peanut butter
-
1 cup sweetened condensed milk or powdered sugar (depending on your preferred version)
(Choose sweetened condensed milk for a softer, creamier fudge, or powdered sugar for a firmer, more traditional texture.)
How to Make 2-Ingredient Peanut Butter Fudge
Step 1: Prepare the Pan
Line a small square baking dish with parchment paper or lightly grease it. This makes removing and cutting the fudge much easier later.
Step 2: Mix the Ingredients
In a medium bowl, combine the peanut butter and your chosen sweetener.
-
If using sweetened condensed milk, stir until the mixture is smooth and glossy.
-
If using powdered sugar, mix until thick and fully blended, with no dry spots.
If the peanut butter is stiff, warming it slightly in the microwave for 10–15 seconds can make mixing easier.
Step 3: Set the Fudge
Transfer the mixture into the prepared dish and spread it evenly with a spatula, pressing it gently into the corners.
Step 4: Chill Until Firm
Place the dish in the refrigerator for 1–2 hours, or until the fudge is firm enough to cut cleanly.
Step 5: Slice and Serve
Lift the fudge out using the parchment paper, cut into small squares, and enjoy.
