Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour two round cake pans to ensure a lovely release once they're baked.
Mix Dry Ingredients: In a bowl, whisk together the all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, and salt. This blend of spices is what makes this cake so special!
Mix Wet Ingredients: In another large bowl, combine the applesauce, granulated sugar, buttermilk, vegetable oil, eggs, and vanilla extract. Mix well until everything is smooth and perfectly blended.
Combine: Gradually add the dry ingredients to the wet mixture. Stir gently until everything is just combined. Be careful not to overmix; we want a fluffy cake!
Pour and Bake: Divide the batter evenly between the prepared pans, smoothing out the tops. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Allow the cakes to cool in the pans for about 10 minutes. After that, transfer them to a wire rack to cool completely.
Frost: Once the cakes are cool, top each layer generously with cream cheese frosting. Stack them for a beautiful presentation!
