Making Flourless Oatmeal Carrot Cake is simple when you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan or line it with parchment paper.
2. Prepare Oats: If you prefer a finer texture, pulse rolled oats in a food processor until they resemble flour. Otherwise, you can use them whole for a chewier texture.
3. Mix Wet Ingredients: In a large mixing bowl, combine the grated carrots, applesauce, vegetable oil, eggs, and vanilla extract. Mix well until all ingredients are smooth.
4. Combine Dry Ingredients: In a separate bowl, blend the rolled oats, brown sugar, baking powder, baking soda, cinnamon, nutmeg, and salt.
5. Mix All Ingredients: Gradually add the dry ingredient mixture to the wet mixture, stirring gently until just combined. Be careful not to overmix.
6. Add Nuts: If desired, fold in chopped walnuts or pecans for added crunch and flavor.
7. Pour Batter: Pour the batter into the prepared cake pan, smoothing the top with a spatula.
8. Bake: Place in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove from the oven and let the cake cool in the pan for about 15 minutes. Then transfer it to a wire rack to cool completely.
10. Serve or Store: Once cool, the cake can be sliced and served or covered to store for later enjoyment.

These straightforward steps allow anyone to craft this delectable cake with ease!
