Easy Microwave Peanut Butter Fudge
You’re 4 ingredients away from creamy, extra peanut buttery fudge! Microwave peanut butter fudge comes out smooth and creamy with less than 10 minutes of prep.
Equipment
- 8×8″ baking pan (you can also use a 9×9″ pan if needed)
Ingredients
- 1 cup smooth peanut butter
- 2 ½ cups confectioner’s sugar sifting recommended
- 1 cup salted butter (2 sticks)
- 2 teaspoons vanilla extract
Instructions
- Grease or line an 8×8” baking pan with parchment paper (so you can easily lift the fudge out of the pan).
- Melt butter and peanut butter in the microwave, until butter is just melted. Add vanilla and stir until uniform. Add sugar and stir until smooth. If there are lumps, microwave mixture in increments of 15 seconds, stirring vigorously every increment, until lumps dissolve.
- Pour and spread evenly in prepared pan. Refrigerate for about 2 ½ hours, until set. Slice.
Notes
- Stay away from natural peanut butter. Use regular smooth peanut butter.
- See my post above for mix-ins and variations!
- If you’re using unsalted butter, add in ½ teaspoon salt.
- If you don’t have a sifter, you can simple add in unsifted sugar and work the lumps out by heating the mixture according to the steps above.
- If you’d like to make a pretty design on top of your fudge, refrigerate the prepared pan of fudge for a few minutes until it just starts to set. Then use a spatula to make a pretty swirl design, and place your fudge back in the fridge to finish setting!
- Run a knife under hot water to slice fudge with ease.
- Fudge keeps well at room temperature for 1-2 weeks, in the fridge for about 3 weeks, and in the freezer for 3 months.
- If you like your fudge soft, enjoy at room temperature. If you like your fudge more dense, enjoy chilled.
