First, lightly grease two microwave-safe mugs or ramekins, each capable of holding at least 6 ounces. This helps prevent sticking and ensures your pancakes pop out easily.
In a medium-sized mixing bowl, combine all your dry ingredients: the almond flour, protein powder, granular sweetener, cinnamon, baking powder, and salt. Whisk them together until everything is well blended.
Next, add the wet ingredients to your dry mix: the large egg, almond milk, avocado oil (or melted butter), and vanilla extract. Stir gently until you have a smooth, lump-free batter.
Now, divide this delicious batter equally between your two prepared mugs.
Microwave one mug at a time on 50% power for 60 to 90 seconds. Keep a close eye on it; the pancake is ready when it looks puffed up and just cooked through. Be careful not to overcook it, as it can become dry.
Carefully remove the mugs from the microwave and let your fluffy mug pancakes cool for a few minutes before serving. Enjoy them plain or with your favorite keto-friendly toppings!
