Mix Dry Ingredients
In a microwave-safe mug, add the almond flour, baking powder, erythritol, and cinnamon (if using). Use a fork to stir until the dry ingredients are evenly combined.
Add Wet Ingredients
Crack the egg into the mug and whisk it into the dry mixture. Add the unsweetened almond milk and melted butter (or coconut oil). Stir until the batter is smooth and free of lumps.
Cook in the Microwave
Microwave the mug on high for 90 seconds. The pancake should puff up and set in the middle. If it’s still slightly undercooked, microwave in 10-second intervals until done.
Cool Slightly and Top
Let the pancake cool for 1-2 minutes before adding toppings. This prevents the pancake from being too hot and ensures it holds its shape.
Serve and Enjoy
Top with fresh strawberries, blueberries, or sugar-free syrup for added sweetness, and enjoy straight from the mug with a fork!
