Description
This Banana Oat Microwave Mug Cake is a warm, soft, and comforting single-serve treat made with ripe banana and hearty oats. It tastes like banana bread but comes together in just minutes in the microwave.
Ingredients
Ripe banana (about 1/2 cup mashed)
1/4 cup rolled oats
2–3 Tbsp milk (dairy or plant-based)
1/8 tsp baking powder
1–2 tsp honey or maple syrup (optional)
1/4 tsp vanilla extract (optional)
Pinch of cinnamon (optional)
Pinch of salt
Instructions
- Place the ripe banana in a microwave-safe mug and mash thoroughly with a fork until mostly smooth.
- Add the rolled oats, milk, baking powder, honey or maple syrup, vanilla extract, cinnamon, and salt to the mug. Stir until a thick, even batter forms.
- Microwave on high for 1 to 1 1/2 minutes, watching closely after the first minute to avoid overcooking. The cake should look set on top but remain soft.
- Carefully remove the mug from the microwave and let it cool slightly before enjoying directly from the mug or turning it out onto a plate.
Notes
For a dessert-style version, stir in 1 Tbsp chocolate chips.
Add chopped nuts or a spoonful of peanut butter to the center for extra texture and richness.
For added protein, mix in 1 tsp chia seeds or a small scoop of protein powder, adding a splash more milk if needed.
Use certified gluten-free rolled oats to make this recipe gluten-free.
Store covered in the refrigerator for up to 1 day and reheat for 15–20 seconds.
