Preheat your oven to 350°F (175°C). Grease a 9-inch cake pan and set aside.
In a large bowl, mix together the ground oats, baking powder, baking soda, cinnamon, nutmeg, and salt.
In another bowl, whisk together the eggs, oil, honey, and vanilla until well combined.
Stir in the grated carrots and apple into the wet ingredients. Add raisins or nuts if using.
Combine the wet and dry ingredients, stirring just until the mixture is well blended.
Pour the batter into the prepared cake pan, smoothing the top with a spatula.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely.
This cake is perfect for serving as a dessert, snack, or even breakfast. The natural sweetness from the apples and carrots makes it a hit with all who try it, and the hearty texture from the oatmeal ensures that it’s both filling and satisfying. Enjoy a slice with a cup of tea or coffee for a truly delightful experience. Happy baking!
