Ingredients
- 4 ripe bananas (2 for batter, 2 for topping)
- 1 egg
- 1/3 cup (80 ml) milk (dairy or non-dairy like almond or oat milk)
- 1 cup (100 g) oats (use certified gluten-free oats if needed)
- 1 tsp baking powder
- 1 pinch of salt
- ½ tsp ground cinnamon
- ⅓ cup chopped walnuts
- 1 tbsp unsweetened cocoa powder (for topping)
- Strawberries, to taste (for garnish)
Q1: Can I make this recipe vegan?
A: Yes! Simply replace the egg with a flax egg (1 tbsp flaxseed meal + 2.5 tbsp water, mixed and rested 5 mins) and use a plant-based milk. The texture remains moist and tender.
Preparation Method
1. Make the batter:
- In a bowl, mash 2 bananas with a fork until smooth.
- Add the egg and milk, and stir until combined.
- Mix in the oats, baking powder, salt, cinnamon, and chopped walnuts. Stir until evenly mixed.
2. Fill the mugs:
- Lightly grease 2–3 microwave-safe mugs.
- Fill each mug halfway with the batter (it will rise as it cooks).
3. Cook:
- Microwave each mug one at a time for 2–3 minutes on high, until set in the center. Let sit for 1 minute before topping.
Q2: Can I bake this instead of using a microwave?
A: Absolutely. Bake in a preheated oven at 350°F (175°C) for about 15–20 minutes in small ramekins or muffin tins, until a toothpick comes out clean.
Cocoa Topping & Garnish
1. Make the topping:
- Mash the remaining 2 bananas and mix with 1 tbsp unsweetened cocoa powder to create a naturally sweet chocolate sauce.
2. Decorate:
- Spoon the cocoa banana topping over the mug cakes.
- Garnish with fresh sliced strawberries for a sweet, refreshing finish.
Serving Tips
- Best served warm, straight from the mug.
- Great with a spoonful of nut butter or a sprinkle of coconut flakes.
