This vegan peanut butter fudge is made in the microwave and ready in 10 minutes! It’s creamy and smooth and insanely delicious.


  • 1 cup (225g) Vegan Butter
  • 1 cup (250g) Peanut Butter (smooth, salted)
  • 1 tsp Vanilla Extract
  • 4 cups (480g) Powdered Sugar


  1. Place the vegan butter and peanut butter into a microwave safe dish with a lid. Microwave for 2 minutes.
  2. Bring it out to stir and stir very well so that the peanut butter and butter is well combined. Then return to the microwave for another 2 minutes. Keep an eye on it during the second 2 minutes and if it starts boiling, you can bring it out, it’s done.
  3. Add the vanilla and powdered sugar and mix in. If your bowl is too small, move into a bigger bowl where you can really get your arm into it! Mix into a smooth fudge.
  4. Transfer to an 8×8 inch square* parchment lined dish and smooth down with a spoon.
  5. Place into the fridge to set. Once the fudge has set, lift the whole block of fudge out with the parchment paper and cut into small squares.


*You can also use a 9×9 inch square dish. If using an 8×8 dish your fudge will be thicker, if using a 9×9 dish your fudge will just be a little thinner but still absolutely great.

*Make it on the stovetop: If you don’t have a microwave or don’t want to use the microwave then you can also make this peanut butter fudge on the stove.¬†Add the vegan butter and peanut butter to a pot on the stove and heat together, stirring occasionally and keeping a close eye on it, until it reaches a boil. When it boils, remove the pot from the heat and immediately add in the powdered sugar and vanilla and stir into a thick fudge. Transfer to your parchment lined square dish and smooth down. Refrigerate until set.

*This fudge stores very well at room temperature for up to a week or in the fridge for 2 weeks. It is also freezer friendly if you want to freeze it.
