Prep: 5 mins
Cook: 2 mins
Total: 7 mins



  • 1 large egg
  • 2 tablespoons melted butter or coconut oil
  • 2 tablespoons milk dairy or non-dairy
  • 2 tablespoons granulated sugar of choice coconut, brown or white
  • 1 tablespoon maple syrup
  • ½ teaspoon vanilla


  • ¼ cup oat flour
  • ¼ cup vanilla protein powder
  • ½ teaspoon baking powder
  • 2 tablespoons chocolate chips


  • In a mug (at least 12 ounces), whisk together all wet ingredients until smooth.
  • Whisk in the dry ingredients, aside from the chocolate chips.
  • Once smooth, whisk in 1 tablespoon of the chocolate chips, then add the remaining 1 tablespoon on top.
  • Microwave on high for 60-80 seconds. The mug cake will rise quite a bit as it's baking, but it will come down when it cools.
  • Check it at 60 seconds and add about 10 seconds more as needed so it doesn't dry out.
  • Let sit for 5 minutes, then serve as is or with a scoop of vanilla ice cream or your favorite frosting.


I have not tested this recipe using all maple syrup, but let me know if you do. You may need to add a few extra seconds of cook time.
For a more keto friendly version, you can sub the sugar for something like erythritol and use a keto friendly syrup for the maple syrup.
