PB&J Muffin in a Mug

I’m not quite sure what happened, but somewhere along the line this muffin ended up tasting like cake.


With a super fluffy texture, light vanilla bean taste, and just the right amount of sweetness, this PB&J muffin could seriously rival any slice of cake… And probably come out on top. Especially when you compare the amount of calories contained in one slice of classic yellow cake compared to those contained in this easy to make muffin!

Also, who doesn’t love a good throwback to their childhood?


When my younger sister was four and my mom first asked me to make her a PB&J, I created the “next big thing”. She wasn’t a huge fan of crust, so instead of spending the time cutting the edges off the bread, instead I used the peanut butter lid to cut her sandwich into a circle. When I explained this to my mom, I smiled widely and announced I had created the best invention ever. Imagine if I can sell these already made in stores, I would save so many people so much time! I thought to myself, imagining all the dolls I could buy when I became a millionaire of my one-of-a-kind invention.

However, when my mom returned home from the store that Sunday afternoon, she had some bad news…

My phenomenal invention had already been created and was in fact being sold in the grocery store. No new dolls for me.

While I didn’t succeed in creating the coolest invention ever as a nine-year-old, I must say, this mug cake comes pretty close. It’s gluten free, can be dairy free, and contains little to know sugar.


And did I mention: it tastes like cake!

PB&J Muffin in a Mug

  • 1/4 c gluten free flour (I used King Arthur Brand. You can also sub with other flour of your choice.)
  • 2 tbs vanilla yogurt of choice (I used Silk Dairy Free)
  • 1 egg white (or 3 tbs egg whites)
  • 1/4 tsp vanilla
  • 1/2 tsp baking powder
  • 1 tbs peanut butter
  • sweetener to taste
  • jam of choice

Add flour and baking powder to a small bowl and stir until combined. Add yogurt, egg white, vanilla, and peanut butter and stir until smooth. Sweeten to taste. Grease a mug and pour in batter. Microwave on high for 1 minute 20-40 seconds. Remove and top with jam and additional peanut butter. Enjoy!
