Yield: Serves 6–8
-
Cake Size: 20 cm / 8-inch round pan
Ingredients
-
1 cup (approx. 90 g) rolled oats
-
200 ml (approx. ¾ cup + 1 tbsp) milk (dairy or plant-based)
-
3 large eggs
-
Pinch of salt
-
20 g (approx. 2 tbsp) unsweetened cocoa powder
-
2 ripe bananas
-
1 apple, peeled and diced
-
Ground cinnamon, to taste (about ½ to 1 tsp)
Step-by-Step Cooking Directions
1. Preheat and Prepare the Pan
Preheat your oven to 180°C (360°F). Lightly grease a 20 cm (8-inch) round baking dish or line it with parchment paper for easier cleanup.
2. Mix the Wet Ingredients
In a mixing bowl, mash the bananas with a fork until smooth. Add the eggs and beat them in. Pour in the milk and stir until everything is well combined.
3. Add the Dry Ingredients
Stir in the oats, cocoa powder, and a pinch of salt. Mix until the ingredients are fully incorporated. The cocoa will give a deep chocolate color and a hint of rich flavor without overwhelming the fruit.
4. Fold in the Apples and Cinnamon
Add the peeled and diced apple into the batter. Sprinkle in cinnamon to taste—around ½ teaspoon for a light flavor or more for a bolder spice. Fold the mixture gently until the apples and cinnamon are evenly distributed.
5. Pour and Bake
Transfer the mixture into the prepared baking dish. Smooth the top with a spatula. Bake in the preheated oven for 45 minutes, or until a toothpick inserted into the center comes out clean and the cake has firmed up.
6. Cool and Serve
Let the cake cool slightly before slicing. Serve warm or at room temperature, plain or with a drizzle of yogurt or nut butter.

Frequently Asked Questions
1. Can I use steel-cut oats instead of rolled oats?
Steel-cut oats are not recommended for this recipe as they require longer cooking and would not soften properly during baking.
2. How ripe should the bananas be?
The riper, the better! Look for bananas with brown spots—they’re sweeter and mash more easily.
3. Can I make this cake vegan?
Yes. Replace each egg with a flax egg (1 tbsp ground flaxseed + 3 tbsp water), and use plant-based milk.
4. Can I store leftovers?
Absolutely. Store in an airtight container in the fridge for up to 4–5 days. Reheat gently or enjoy cold.
5. Can I freeze this cake?
Yes. Slice it, wrap individually, and freeze for up to 2 months. Thaw overnight in the fridge or microwave from frozen.
6. What kind of milk should I use?
Any type works—dairy milk, almond, oat, or soy. For creaminess, oat or whole milk is ideal.
7. Is it sweet enough without added sugar?
If your bananas are ripe, yes. But you can add 1–2 tablespoons of honey or maple syrup if you prefer a sweeter cake.
8. Can I use pears instead of apples?
Definitely! Pears are a great substitute and offer a similar texture and sweetness.
9. How do I know when the cake is done?
Insert a toothpick into the center—if it comes out clean or with just a few moist crumbs, it’s ready.
10. Can I blend the batter for a smoother texture?
Yes. Blend all ingredients for a uniform, fudgy cake texture. It’s especially good if serving to toddlers or picky eaters.
