This easy peanut butter fudge recipe is made with only 3 ingredients! Everything cooks in the microwave together and only takes 5 minutes to prepare. No candy thermometer needed for this quick and easy fudge!
Line an 8x8 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.
Carefully remove from the microwave and stir really well.
Microwave on high for an additional two minutes.
Carefully remove the bowl from the microwave and stir again.
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.
