This easy 3-ingredient peanut butter fudge recipe will soon become your favorite dessert to eat.

Prep Time 1 minute
Cook Time 1 minute
Additional Time 2 hours
Total Time 2 hours 2 minutes


  • Peanut butter
  • Vanilla frosting
  • Flaky salt (optional)


  1. Add peanut butter to a microwave-safe bowl and microwave for 20 seconds. Keep heating the peanut butter in 20-second rounds until it has melted. 
  1. Put the vanilla frosting into the bowl and microwave for another 20 seconds. Once the frosting has melted, mix the two ingredients until you get a smooth texture. 
  2. Pour the mixture into a lined baking pan (8 x 8 inches is used in this recipe). If adding flaky salt, sprinkle the top of the fudge before placing it into the fridge.
  3. Put the baking pan into the fridge for a minimum of 2 hours, or until it feels firm. 
  4. Once it is solid enough to cut, slice the fudge into square-shaped pieces. 


I recommend using smooth peanut butter as crunchy peanut butter won't melt easily.

Flaky salt is completely optional, but if your peanut butter is unsalted, try to add some salt. 

Make sure to watch over the peanut butter. It burns easily!

Depending on your frosting, you may not need to microwave it. If it's already smooth, whisk it into the melted peanut butter without adding it to the microwave.

  • To store this peanut butter fudge, place it in an airtight container in the fridge for up to a month. 


Keeping your new year’s resolutions strong doesn’t have to be a chore. Eating healthy and deliciously can go hand in hand. Try this sweet, but healthy peanut butter fudge recipe, and fulfill all of your cravings.
