Fluffy Banana Mug Cake with Oat Flour (Gluten-Free & Naturally Sweetened)

Whip up a fluffy banana mug cake in just minutes for a warm, comforting treat that’s naturally sweetened and gluten-free. Perfect for beginner bakers, this single-serve cake uses wholesome ingredients like ripe banana, oat flour, and eggs for a quick dessert or snack you can feel good about.

1. 1
   In a small mixing bowl, mash the banana thoroughly. Whisk in the eggs until well combined and smooth.
2. 2
   Stir in the gluten-free oat flour, baking powder, and cinnamon (if using) until the batter is fully mixed and smooth.
3. 3
   Lightly grease a large microwave-safe mug or two smaller ramekins with coconut oil or nonstick spray. Make sure to use a mug large enough to allow the cake to rise without overflowing.
4. 4
   Microwave on high for 1.5 to 2 minutes (800W), or until the cake has set and puffed up. Alternatively, bake in a preheated oven at 180°C (350°F) for about 20 minutes, or until a toothpick comes out clean.
5. 5
   Let cool slightly before topping with peanut butter, fresh berries, or a drizzle of maple syrup. Grab a spoon and dig in while it’s warm!
