Why You’ll Love This Recipe

Genuinely ready in one minute — mix in the mug, microwave, and eat while it’s still warm

Uses that single brown banana sitting on your counter without committing to a full batch

Pro Tips

Mash the banana completely smooth — lumps create uneven cooking and gummy pockets in the finished cake
Don’t overfill the mug — use a 12-ounce or larger mug and fill only halfway to prevent overflow during cooking
Check doneness at 50 seconds if using a powerful microwave (1000+ watts), then add time in 10-second bursts to avoid rubbery texture
Let it rest for 30 seconds after microwaving — the cake continues cooking slightly and firms up to the perfect texture

Ingredients Method

Ingredients

1 ripe banana mashed until smooth
1 large egg beaten
3 tablespoons all-purpose flour
2 tablespoons granulated sugar
1 tablespoon vegetable oil or melted butter
1/4 teaspoon baking powder
1/4 teaspoon vanilla extract
1 pinch of cinnamon
1 pinch of salt

Method

Mash the banana in a large microwave-safe mug (at least 12 ounces) with a fork until completely smooth with no lumps remaining.
Add the beaten egg, oil, vanilla extract, and sugar to the mug. Stir vigorously with a fork until fully combined and slightly frothy.
Add the flour, baking powder, cinnamon, and salt directly to the mug. Mix just until no dry streaks remain, being careful not to overmix.
Tap the mug gently on the counter 2-3 times to release any air bubbles and ensure the batter is evenly distributed.
Microwave on high power for 50-60 seconds, watching closely. The cake is done when the center is just set and springs back lightly when touched.
Let the mug cake rest for 30 seconds before eating. The texture will firm up slightly as it cools. Serve directly from the mug or invert onto a plate.

Frequently Asked Questions

Can I make this without a microwave?

Yes, pour the batter into a greased ramekin and bake at 350°F for 12-15 minutes, until a toothpick inserted in the center comes out clean.

What if my banana isn’t very ripe?

The riper the better for natural sweetness and moisture. If using a barely-spotted banana, add an extra teaspoon of sugar and a splash more milk to compensate.

Why is my mug cake rubbery?

Overcooking is the culprit. Microwaves vary wildly in power — start checking at 50 seconds and add time in small increments until just set in the center.

Can I add mix-ins like chocolate chips or walnuts?

Absolutely. Stir in 1-2 tablespoons of chocolate chips, chopped nuts, or even a spoonful of Nutella before microwaving for extra indulgence.

Storage & Serving

This mug cake tastes best eaten immediately while warm and tender. If needed, refrigerate leftovers covered for up to 24 hours and reheat for 15-20 seconds. Serve straight from the mug with a dollop of whipped cream, a drizzle of maple syrup, or a scoop of vanilla ice cream for an instant dessert upgrade.
