How to make this quick fudge recipe
For the full set of recipe directions, make sure you scroll down to the recipe card below.
- Line an 8×8 pan with parchment paper. Make sure you have some overhang on the sides so you can easily pull the fudge out later.
- In a large microwave safe bowl, place the butter and peanut butter.
- Microwave on high for two minutes.
- Stir really well.
- Microwave on high for an additional two minutes.
- Carefully remove the bowl from the microwave. Add the powdered sugar to the mixture and stir to combine. The mixture will become a thick paste like batter.
- Spread the mixture into the prepared baking dish. Place a square of additional parchment on top of the fudge and use your hands to smooth/pat the surface to get it even.
- Place the dish in the refrigerator and let it cool and set for two hours.
- Remove the fudge from the dish using the parchment paper overhang. Cut into 1” squares.
Recipe Tips
- Avoid using natural peanut butter as the consistency can vary and affect the texture of the fudge.
- Use a large sharp knife with a thin edge that has been heated under hot water and dried well to cut the fudge into nice clean lines.
Recipe Variations
You can change this fudge up with a few simple additions
- Drizzle melted chocolate on top after it has set.
- Sprinkle some flake salt on top before setting in the fridge.
- Instead of creamy peanut butter, use chunky to give a bit of texture to your fudge.
- Mix in some Reece’s Pieces or chopped peanut butter cups into the batter.
How do you store fudge?
The best way to store fudge is in an air-tight container in the refrigerator for 2-3 weeks.
I remember my grandmother always storing it wrapped in plastic wrap, and then waxed paper, and then placing it in a glass container. You don’t have to go quite so gung-ho over it, but keeping it nice and air tight keep it from drying out.
