  • 2 Tablespoons unsalted butter plus more to grease the cups - substitute coconut oil for dairy-free
  • 2 Tablespoons monkfruit/erythritol sweetener I used Lakanto Golden Monkfruit
  • 1 Tablespoon unsweetened almond milk or substitute coconut milk if preferred
  • 1/2 teaspoon pure vanilla extract
  • 1/16 teaspoon sea salt "a pinch"
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon cream of tartar just for flavor, you can leave it out if you like
  • 1/2 teaspoon ground cinnamon use 1 teaspoon for more intense flavor
  • 1 large egg white
  • 1/2 cup blanched almond flour


  • Place butter in a microwave safe bowl and heat in the microwave until almost completely melted. (30 seconds in 1200 watt microwave)
  • Stir butter with a fork until melted and smooth. Add the sweetener and stir to thoroughly combine.
  • Add the almond milk, vanilla, baking powder, pinch of sea salt, cream of tartar, and egg white. Stir to thoroughly combine.
  • Stir in the almond flour, making sure it is completely mixed in.
  • Grease two microwave safe coffee mugs (or ramekins) that are at least 8 ounces each. Divide the batter evenly between the mugs and smooth the top.
  • Place both mugs in the microwave and cook for 1 minute and 30 seconds on HIGH if using a 1200 watt microwave. Time will vary depending on your microwave, but add 5 seconds at a time until you determine the perfect time.
  • Allow to cool for five minutes before serving, they are very hot!


  • Cooking time is deceiving, I cannot add 30 seconds to the time.
