Mini Version
1/2 cup oats
1 banana
1 egg
10 g unsweetened cocoa powder
0.5 tsp baking powder
10 g almonds
Step-by-Step Cooking Directions
Step 1: Soak the Oats
In a large mixing bowl, combine 120 g of oats with 250 ml of hot milk. Stir and let them soak for about 10 minutes. This softens the oats and creates a creamy base for your cake.
Step 2: Prepare the Bananas and Eggs
Mash the bananas in a separate bowl until smooth. Add the eggs and mix until fully combined.
Step 3: Combine Wet and Dry Ingredients
Add the banana-egg mixture to the soaked oats. Mix well. Then stir in the cocoa powder, baking powder, and chopped nuts.
Step 4: Prepare the Baking Dish
Line a baking dish with parchment paper and lightly grease it with vegetable oil to prevent sticking.
Step 5: Pour and Bake
Pour the batter into the prepared baking dish. Preheat your oven to 180°C (350°F) and bake for 40 minutes, or until a toothpick inserted in the center comes out mostly clean.
Step 6: Melt the Chocolate
While the cake bakes, gently melt the dark chocolate using a double boiler or microwave in 30-second intervals, stirring in between until smooth.
Step 7: Serve
Once the cake is baked and slightly cooled, drizzle with melted dark chocolate. Slice and serve warm or at room temperature.
Mini Cake Variation
Mix 1/2 cup oats, 1 banana, 1 egg, 10 g cocoa, 0.5 tsp baking powder, and 10 g almonds. Pour into a small, greased, and lined dish. Bake at 180°C for 20 minutes.
