Cooking Time

• Preparation Time: 15 minutes

• Cooking Time: 5 minutes

• Chill Time: 1 hour

• Total Time: 1 hour 20 minutes

Ingredients

• 200 g oats

• 2 ripe bananas

• 30 g unsweetened cocoa powder

• 3 g ground cinnamon

• 1 additional ripe banana (for filling)

• 100 g dark chocolate

• 1 tablespoon neutral oil (e.g., coconut or sunflower)

• 30 g chopped nuts (walnuts, hazelnuts, or almonds work well)

• Oil for greasing pan

Step-by-Step Cooking Directions

1. Toast the Oats
   In a dry skillet, toast 200 g of oats over medium heat for 2–3 minutes, stirring constantly to avoid burning. Once they turn slightly golden and release a nutty aroma, remove from heat and let them cool completely.

2. Make the Dough
   In a food processor, combine the toasted oats, 2 ripe bananas, cocoa powder, and cinnamon. Blend until a thick dough forms. Divide the mixture into two equal parts.

3. Prepare the Cake Base
   Lightly grease a 16 cm (6.3-inch) springform or cake pan with a little oil. Press one half of the dough into the bottom of the pan, smoothing it out evenly to form the first layer.

4. Add the Filling
   Slice the additional banana and place it evenly on top of the first layer. This will give your cake a natural sweetness and a soft center.

5. Top and Chill
   Press the second half of the dough over the banana layer, smoothing it out to form the top of the cake. Cover and refrigerate for at least 1 hour to set.

6. Make the Chocolate Glaze
   Melt 100 g dark chocolate with 1 tablespoon of oil in a heatproof bowl over a pot of simmering water or in the microwave in 20-second intervals. Stir until smooth and glossy.

7. Finish with Chocolate and Nuts
   Once the cake has chilled and firmed, remove it from the pan. Pour the chocolate glaze over the top and spread it evenly. Sprinkle chopped nuts over the glaze while it’s still warm. Let the chocolate set before serving.

Common Mistakes to Avoid

Pairing Recommendations

• Other foods: Serve alongside fruit salad or a protein-rich smoothie for a balanced snack

Cooking Tips

• For a smoother texture: Use quick oats or pulse rolled oats a few times in a blender

• Add flavor depth: A dash of vanilla extract or orange zest enhances the taste

• For firmer texture: Add a tablespoon of almond flour or flaxseed meal
