Preheat your oven to 350°F (175°C) and prepare an 8-inch round baking pan by greasing it with cooking spray or lining it with parchment paper.

In a large mixing bowl, combine rolled oats, grated carrots, mashed ripe bananas, eggs, honey, and cinnamon. Stir until all ingredients are well incorporated.

Transfer the mixture to a food processor or blender and pulse until smooth for a finer texture.

Pour the batter into the prepared baking pan and smooth the top with a spatula.

Bake for 25-30 minutes until the top is golden brown and a toothpick inserted into the center comes out clean.

After baking, allow the cake to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
