Ingredients

Main Cake

• 120 g oats

• 250 ml hot milk

• 2 ripe bananas

• 2 eggs

• 45 g unsweetened cocoa powder

• 1 tsp baking powder

• 45 g chopped nuts (e.g., walnuts or almonds)

• 75 g dark chocolate

• Vegetable oil (for greasing)

• Baking paper

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.

Common Mistakes to Avoid

• Skipping the oat soaking step: This ensures tenderness and helps with moisture distribution

• Using underripe bananas: Ripe bananas add more sweetness and better texture

• Overmixing the batter: Mix until just combined to avoid a gummy texture

• Using too much cocoa: It can make the cake dry—stick to the recommended amount

• Not checking the bake early: Oven temperatures vary—check around 35 minutes

• Pouring melted chocolate on a hot cake: Let it cool slightly or the chocolate will melt too thin

Pairing Recommendations

• Drinks: Pair with espresso, chai tea, oat milk latte, or a chocolate protein shake

• Fruits: Serve with sliced strawberries, kiwi, or blueberries

• Toppings: Drizzle with honey, maple syrup, or a thin chocolate glaze

• Savory balance: Serve alongside a boiled egg or cottage cheese for a balanced breakfast

• Dessert pairing: Add a scoop of vanilla frozen yogurt for a healthier dessert plate

Cooking Tips

• For extra richness, use 1 tbsp of melted coconut oil in the batter

• To make vegan, use flax eggs (1 tbsp flaxseed meal + 3 tbsp water per egg)

• Add a handful of chocolate chips or raisins for variety

• Want it denser? Blend half the oats before soaking for a smoother texture

• Sprinkle sea salt on the melted chocolate topping for contrast

• Use silicone molds for mess-free mini cakes or muffins

Ingredient Spotlight: Oats

Oats are the heart of this cake, offering not only structure but major health benefits. Naturally gluten-free (if certified), they’re loaded with soluble fiber—particularly beta-glucan—which supports heart health, reduces cholesterol, and improves gut function. Oats also provide lasting energy without spiking blood sugar and contain valuable nutrients like manganese, iron, and B vitamins. Their mild, nutty flavor and absorbent nature make them a versatile base for healthy baking.

Yes! Pour batter into muffin tins and bake at 180°C (350°F) for 20 minutes.

7. What kind of nuts work best?
