2. Prepare the Batter

• In a separate bowl, mash 2 ripe bananas until they form a smooth, lump-free mixture. Bananas will add natural sweetness and moisture to the cake.
• In a large mixing bowl, whisk together 2 eggs with 1 g of sweetener (optional). If your bananas are very ripe, you may not need the additional sweetener. Adjust based on your taste preference.
• Add the mashed bananas, 30 g (¼ cup) of cocoa powder, and 5 g (1 tsp) of baking powder to the egg mixture. Stir well until all the ingredients are combined and the batter is smooth.

3. Combine Ingredients

Once the oats have softened in the milk, add them to the banana and egg mixture. Stir until the oats are fully incorporated into the batter, ensuring an even consistency.

4. Add Walnuts

Fold in 30 g (1 oz) of chopped walnuts. The walnuts add a satisfying crunch and a nutty flavor that pairs beautifully with the chocolate and banana.

5. Bake

• Preheat your oven to 180°C (350°F).
• Grease a cake pan or line it with parchment paper to prevent sticking.
• Pour the batter into the prepared cake pan, spreading it evenly.
• Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The cake should be firm but slightly springy to the touch.

6. Add Chocolate

Once the cake has fully cooled, melt 30 g (1 oz) of dark chocolate and drizzle it over the top of the cake. You can also chop the dark chocolate and sprinkle it on top if you prefer a chunkier texture.
