Ingredients:
1/2 ripe banana, mashed
1/4 cup (22g) rolled oats (old-fashioned or quick-cooking)
1 large egg

Instructions:
1. Prepare Banana:
In a microwave-safe mug (at least 12 oz / 350 ml capacity), mash the ripe banana thoroughly with a fork until very smooth.
2. Add Wet Ingredients:
Add the egg, vanilla extract (if using), and salt (if using) to the mashed banana. Mix well with a fork until fully combined.
3. Add Dry Ingredients:
Stir in the rolled oats, baking powder, and cinnamon. Mix until just combined. Avoid overmixing.
4. Add Chocolate Chips (Optional):
If using sugar-free chocolate chips, stir most of them into the batter. Reserve a few for the top.
5. Cook:
Place the mug in the microwave. Cook on high for 1 to 2 minutes. The exact time will depend on your microwave’s wattage. Start with 1 minute, then add 15-30 second intervals until the cake looks set and springs back when lightly touched. It should not be jiggly in the center. Do not overcook, or it will become dry.
6. Top & Serve:
Immediately after cooking, if you reserved some chocolate chips, sprinkle them on top. They will melt slightly from the heat. Let the mug cake cool for 1-2 minutes before enjoying it straight from the mug.

- Helpful Tips for Bakers:
Banana Ripeness:
Use a very ripe banana (with brown spots) for maximum sweetness and moisture.
Mug Size:
Ensure your mug is large enough (at least 12 oz) to prevent overflow as the cake rises during cooking.
Microwave Wattage:
Microwave cooking times vary. Get to know your microwave’s power. It is better to undercook slightly and add more time than to overcook.
Batter Consistency:
If your banana is small or less ripe, the batter might be quite thick. You can add a tiny splash of milk or water (1 teaspoon at a time) to thin it out slightly if needed.
Serving Fresh:
This mug cake is best enjoyed fresh, immediately after cooking. It does not store well.
Variations:
Feel free to experiment with other additions like a sprinkle of chopped nuts, a dash of ginger, or a spoonful of protein powder for an extra boost.
