A quick and easy 3-ingredient banana mug cake made with banana, egg, and almond flour. This gluten-free, single-serving dessert is ready in minutes and naturally sweetened with no added sugar. Perfect for a healthy treat or a last-minute craving!
In a microwave-safe mug, mash the ripe banana with a fork until smooth and no large chunks remain. The riper the banana, the better the flavor!
Crack the egg into the mug with the mashed banana and whisk together until well combined.
Add the almond flour to the banana and egg mixture, stirring until everything is evenly mixed.
Microwave the mixture on high for 1 minute and 30 seconds, or until the cake is set in the center and no longer jiggly. The cooking time may vary slightly depending on the strength of your microwave.
Let the mug cake cool for a minute or two, then enjoy directly from the mug! You can top it with a dollop of yogurt, nut butter, or a sprinkle of cinnamon if desired.
