Peanut Butter and Jelly Mug Cake

This Peanut Butter and Jelly Mug Cake is probably the easiest sweet treat you could make!  It has a perfect peanut butter flavor, delicious jelly swirls throughout, a fluffy texture, and is made with good-for-you ingredients.




  • 1 egg
  • 2 tbsp peanut butter (natural & runny kind!)
  • 2 tbsp applesauce
  • 1 tbsp almond milk
  • 1 tbsp maple syrup
  • 2 1/2 tbsp whole wheat pastry flour or all purpose flour
  • 1/4 tsp vanilla extract
  • 1/4 tsp baking powder
  • pinch of salt

PB&J Swirl

  • 1/2 tbsp peanut butter
  • 1 tbsp jelly of choice


  1. In a (medium/large) mug combine the egg, peanut butter, apple sauce, maple syrup, almond milk, and vanilla extract until smooth.
  2. Add in the flour, baking powder, and salt. Combine until smooth.
  3. Drizzle the peanut butter and jelly on top of the batter. Make the swirl design with a knife or toothpick. This will help the jelly to distribute throughout the cake, but don’t mix it completely in!
  4. Microwave for 2 minutes.
  5. Enjoy!
