Instructions

Mix Dry Ingredients: In a microwave-safe mug, whisk together the protein powder, flour, baking powder, sweetener, and a pinch of salt until well combined.
Add Wet Ingredients: Add the lemon juice, lemon zest, almond milk, melted coconut oil, and vanilla extract to the mug. Stir thoroughly until the mixture is smooth and no dry spots remain. The batter should be thick but easily spoonable.
Microwave: Microwave the mug on high for 40 to 60 seconds. Begin checking at the 40-second mark; if the center is still wet, continue cooking in 10 to 15 second intervals. Do not overcook or the texture may become rubbery.
Cool Slightly: Allow the mug cake to cool for 1 to 2 minutes. This brief rest enhances the lemon flavor and improves the overall texture.
Top and Serve: Add a spoonful of Greek yogurt, a bit of lemon zest, or a drizzle of honey on top. Serve warm and enjoy immediately.
