I LOVE creating new recipes, that’s why I’ve been working hard to get this Peanut Butter M&M’s Mug Cake recipe to perfection. Had nearly every family member test it and I think I finally got it perfect!


  • 2 tablespoons Peanut Butter
  • 2 Fun Size bags of M&M’s or 15 pieces of M&M’s
  • 2 tablespoons butter
  • 1 teaspoon vanilla
  • 1 egg
  • 4 tablespoons flour
  • 1 teaspoon baking powder
  • pinch of salt

Combine all ingredients (besides M&M’s), stir well, add 7 pieces of M&M’s stir,
top with rest of M&M’s and microwave for 90 seconds! 

Enjoy! Top with chocolate syrup and some vanilla ice cream.

  1. I have wanted to try some of the mug cake recipes I keep coming across. Making a personal size cake is great for portion control. Plus, how can you go wrong with peanut butter and M&Ms?

  2. I didn’t know you could make cake in the microwave so easily! I have to try this!

  3. As if mug cake isn’t already awesome. I can’t wait to try this. Peanut butter is my jam. So are M&Ms!

  4. I have yet to try a mug cake, probably because I don’t want to become addicted to having cake so easily. LOL. But this one is calling my name!

  5. i love anything that has peanut butter added to it. lol. this looks amazing i would love this. i total must try.
