Start by whisking together the creamy Greek yogurt, a large egg, fragrant lemon zest, and fresh lemon juice in a medium bowl until well combined.
Next, gently fold in the almond flour, protein powder, your chosen sweetener, baking powder, and a pinch of salt until everything is perfectly mixed into a smooth batter.
Carefully stir in the juicy fresh blueberries, ensuring they are evenly distributed throughout the mix.
Divide this lovely batter equally into two lightly greased mugs or ramekins (at least 4-ounce capacity). This recipe is designed for perfect portion control!
Microwave each mug cake on 50% power for just 2 minutes. Watch as they transform into light and fluffy treats! Let them cool slightly for a few minutes before enjoying your healthy, satisfying dessert.
