Step-by-Step Instructions 👩🍳
Step 1 — Create the Creamy Base
Mash the ripe banana and avocado together until completely smooth and creamy.
The smoother the mixture, the softer the final cake.
💡 Tip: Use very ripe bananas for the best natural sweetness.
Step 2 — Add the Eggs
Crack in the eggs and whisk until the mixture becomes silky and fully combined.
This creates the foundation for a light and tender texture.
💡 Tip: Room-temperature eggs blend more easily.
Step 3 — Mix the Dry Ingredients
Add the oats, baking powder, salt, and optional cinnamon or vanilla.
Stir until no dry spots remain.
💡 Tip: Oat flour creates a smoother cake, while rolled oats add more texture.
Step 4 — Transfer to the Pan
Pour the batter into a lightly greased loaf pan or small baking dish.
Smooth the top with a spoon.
💡 Tip: Line the pan with parchment paper for easy removal.
Step 5 — Add Optional Toppings
Sprinkle chopped nuts or dark chocolate pieces over the top.
These add texture and extra flavor.
💡 Tip: A combination of walnuts and dark chocolate is especially delicious.
Step 6 — Bake Until Golden
Bake at 180°C (350°F) for 25–30 minutes.
The cake should feel set in the center and lightly golden on top.
💡 Tip: Insert a toothpick in the center—it should come out mostly clean.
Step 7 — Cool and Slice
Allow the cake to cool for at least 10 minutes before slicing.
The texture improves as it rests.
💡 Tip: It’s even better after chilling overnight in the refrigerator.
