Preheat your oven to 180°C (350°F).

In a large mixing bowl, combine the oatmeal, yogurt, and eggs. Stir until well blended.

Add the mashed banana and grated apple to the bowl, mixing thoroughly to incorporate.

If using, chop the cashews finely and fold them into the pancake batter for added texture and flavor.

Lightly grease a baking dish with olive oil. Pour the batter into the dish, spreading it out evenly.

Place the dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the pancakes are set.

Remove from the oven and allow to cool slightly before cutting into squares or other desired shapes.

Serve the pancakes warm, garnished with coconut flakes and a sprinkle of cocoa powder or cinnamon powder for extra flavor.
