How to make a keto blueberry mug cake?

This recipe makes two moist keto muffins baked in a mug. To make this easy keto mug cake recipe, you need:

  • Large egg
  • Almond flour – use ultra-fine almond flour with a golden color. If you prefer to use coconut flour, use my coconut flour mug cake recipe and add blueberries to the batter.
  • Erythritol or any keto sweetener you love.
  • Unsweetened almond milk
  • Baking powder
  • Vanilla extract
  • Blueberries – fresh or frozen and an extra 1/2 teaspoon of coconut flour to roll the keto-friendly berries and prevent them from sinking in the bottom of the coffee mug.

Combine dry ingredients to wet ingredients

In a small bowl, beat egg, almond milk vanilla. Then, stir in baking powder, almond flour, and erythritol until a thick batter forms.

In another bowl, stir the blueberries with coconut flour. This is optional, but it prevents the blueberries from sinking to the bottom of the mug.

How to make keto blueberry muffins IN A MUG

Fold in the blueberries and split the keto blueberry muffin batter evenly into two tall coffee mugs. It is essential to use tall coffee mugs because the muffins will rise and might overflow from the mugs.
