Instructions:

Preheat the Oven: Set your oven to 350°F (175°C) and lightly grease a 9-inch round cake pan.

Mix Wet Ingredients: In a medium bowl, whisk together the eggs and vegetable oil until well combined.

Incorporate Sugars and Flavorings: Add the ground cinnamon, dark brown sugar, granulated white sugar, and vanilla extract to the egg mixture, stirring until smooth.

Combine Dry Ingredients: In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, and salt.

Form the Batter: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Fold in the chopped apples and walnuts, ensuring even distribution throughout the batter.

Bake the Cake: Pour the batter into the prepared cake pan, smoothing the top. Bake for approximately 45 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Cool and Serve: Allow the cake to cool in the pan for about 15 minutes before transferring it to a wire rack to cool completely. Once cooled, slice and serve as desired.
