If you make this peanut butter fudge, make sure you have people to share it with — it’s hard to resist. It’s so addictive I could easily polish off the whole batch in a day.
Sometimes eating several pieces of peanut butter fudge makes you a better person.

This fudge needs a few hours to set, but the hands-on prep takes under 10 minutes. There’s no baking and no complicated steps — just a simple, delicious no-bake treat everyone will love.
Technically this isn’t traditional fudge because it contains no milk, but it looks, feels, and tastes like fudge. If a pedant wants to argue, I’ll enjoy my piece anyway.

3 Ingredient Microwave Peanut Butter Fudge (quick and easy!)
Ingredients
- 1 cup butter (2 sticks)
- 1 cup smooth peanut butter (not natural)
- 1 pound powdered sugar
- 1 tsp vanilla extract (optional)
Instructions
-
Grease an 8×8-inch pan with butter, then line it with parchment paper for easy removal.
-
In a large glass bowl, combine the butter and peanut butter. Cover with a paper towel and microwave on high for about 2 minutes.
-
Stir, then microwave 1–2 more minutes depending on your microwave wattage. Be careful — the mixture will be very hot.
-
Add the powdered sugar (and vanilla if using) to the melted mixture. Stir with a wooden spoon or spatula until fully combined.
-
Press the mixture into the lined pan using a spatula. Let it sit on the counter for about 10 minutes, then cover and refrigerate for at least 2 hours to set.
-
When firm, invert the pan onto a cutting board so the fudge releases. Remove the parchment and slice into small squares.
-
Store the fudge in the refrigerator. It keeps well for up to two weeks.
Notes
Tips: Use a smooth, non-natural peanut butter for the creamiest texture. If you like a slightly firmer fudge, chill longer. Cut into bite-size pieces for serving or gifting.
