Ingredients
- 1 ripe banana, mashed
- 1 egg
- 50 ml milk (dairy or plant-based)
- 70 g oatmeal (use gluten-free if necessary)
- 5 g baking powder
- 1 g salt
- 2 g cinnamon
- 20 g walnuts, chopped
Instructions
- Prepare the Oats:
- Preheat your oven to 180°C (350°F) and line a small baking dish or loaf pan with parchment paper or lightly grease it.
- In a blender or food processor, pulse the oats until they reach a flour-like consistency. This will create a smoother cake texture.
- Mix the Wet Ingredients:
- In a mixing bowl, mash the banana until smooth. Add the egg and milk, and whisk until well combined.
- Combine the Dry Ingredients:
- In a separate bowl, combine the ground oats, baking powder, salt, and cinnamon. Mix well to distribute the baking powder evenly.
- Combine Wet and Dry Ingredients:
- Add the dry ingredients to the wet ingredients, stirring until just combined. Avoid over-mixing, as this can make the cake dense.
- Add Walnuts:
- Fold in the chopped walnuts, reserving a few to sprinkle on top if desired.
- Bake the Cake:
- Pour the batter into the prepared baking dish, spreading it evenly.
- Sprinkle the reserved walnuts on top.
- Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
- Cool and Serve:
- Let the cake cool for a few minutes in the pan before transferring it to a wire rack to cool completely.
- Slice and serve as is, or top with a dollop of yogurt or a drizzle of honey for extra flavor.
