How To Make Coconut Flour Banana Mug Cake

Mash banana into a mug.

Mix until smooth and microwave.

Recipe Tips

Use a ripe banana with brown spots for the best sweetness and texture.
Letting the batter rest for a minute or two helps the coconut flour absorb moisture and prevents a gummy texture.
Microwave times may vary-start with 1 minute and add 10-second increments if needed.
If you prefer baking it, cook in an oven-safe ramekin at 350°F (175°C) for about 15-18 minutes.
