Ingredients Method Notes

Ingredients
  

Dry Base
  • 1 ¾ tablespoons coconut flour
  • 1 teaspoon ground flaxseed
  • 2.5 teaspoons granular erythritol or preferred zero-glycemic sweetener
  • 1.5 teaspoons unsweetened shredded coconut
  • ¼ teaspoon baking powder
Wet & Flavor Agents
  • 1 large egg
  • ⅛ cup (2 tbsp) unsweetened almond milk
  • 1 tablespoon avocado oil
  • ½ teaspoon vanilla extract
  • ⅛ teaspoon almond extract

Method
 

  1. In a large, microwave-safe mug (at least 12-14 oz capacity), add the coconut flour, ground flaxseed, erythritol, shredded coconut, and baking powder. Whisk thoroughly with a fork until well-combined and free of lumps.
  2. Create a small well in the center of the dry ingredients. Add the egg, unsweetened almond milk, avocado oil, vanilla extract, and almond extract. Mix vigorously until the batter is completely smooth and uniform.
  3. Microwave on high power for approximately 90 seconds (1 min 30 sec). The cake will puff up significantly and then settle. The surface should spring back when touched, and a toothpick inserted into the center should come out with moist crumbs.
  4. Let the cake cool for 1–2 minutes before enjoying, as the center will be very hot.
