Recipe Yield: 1 serving
INGREDIENTS
1/2 medium ripe banana, mashed (about 2 tbsp)
3 tbsp oat flour (or finely blended oats)
1 tbsp maple syrup (or honey)
1 tbsp milk (dairy or non-dairy)
1/2 tsp vanilla extract
1/4 tsp ground cinnamon
1/4 tsp baking powder
1/8 tsp salt (a small pinch)
1/2 tbsp melted coconut oil (optional, for extra moisture)
1 tbsp chopped walnuts or dark chocolate chips (optional)
INSTRUCTIONS
1. Mash the banana: In a microwave-safe mug, mash 1/2 a ripe banana until smooth. The riper, the better for natural sweetness.
2. Add wet ingredients: Stir in maple syrup, milk, vanilla extract, and melted coconut oil (if using) until well combined.
3. Mix dry ingredients: Add oat flour, cinnamon, baking powder, and salt to the mug. Stir until a smooth batter forms. Fold in walnuts or chocolate chips if using.
4. Microwave: Cook in the microwave for 80-90 seconds, or until the top is set and a toothpick inserted in the center comes out clean. If needed, microwave in 10-second intervals until done.
5. Cool & enjoy: Let it sit for 1-2 minutes to allow flavors to develop before enjoying straight from the mug or transferring to a plate.
Helpful Tips to Perfect This Recipe
- Ripe Bananas = Best Flavor: Use a soft, spotted banana for natural sweetness and extra moisture.
- Check Your Mug Size: Use a 10-12 oz microwave-safe mug to prevent overflow.
- Boost the Texture: Adding 1/2 tbsp coconut oil makes it richer, but it’s still great without!
