Step-by-Step Instructions banana oat cake

Prep the Ingredients

1. Preheat the oven to 350°F (180°C) and grease a baking pan.
2. Soak the oats – Mix oat flakes with milk in a bowl and let them sit for 10 minutes. This softens the oats and helps create a tender cake texture.

Make the Batter

3. In a large bowl, mash the bananas until smooth.
4. Add eggs, baking powder, cocoa powder, vanilla extract, and sweetener (if using). Stir well.
5. Fold in the softened oats and milk mixture.
6. Add chopped walnuts and chia seeds for crunch and texture.

Bake the Cake

7. Pour the batter into the greased baking pan.
8. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

Add the Finishing Touch

9. Once baked, drizzle with melted dark chocolate or sprinkle chopped chocolate on top while still warm.
10. Let cool slightly before slicing and serving.
