Instructions:
- Preheat your oven to 350°F (175°C) and grease a 9×9-inch (23×23 cm) square baking pan.
- In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg. Set this dry mixture aside.
- In a large bowl, cream together the softened butter and 1 cup of granulated sugar until the mixture is light and fluffy. This can take a few minutes.
- Beat in the eggs, one at a time, and then stir in the vanilla extract.
- Gradually add the dry mixture to the wet mixture, alternating with the sour cream. Start and end with the dry mixture. Mix until just combined.
- In a separate bowl, mix the chopped apples with 1/2 cup of granulated sugar and 1 teaspoon of cinnamon.
- Spread half of the cake batter into the prepared pan. Spread the apple mixture evenly over the batter. Drop the remaining cake batter in small spoonfuls over the apples.
- In a small bowl, combine the 1/4 cup granulated sugar, 1/4 cup brown sugar, and 1 teaspoon of cinnamon for the topping. Sprinkle this mixture evenly over the cake batter.
- Bake in the preheated oven for 45-50 minutes or until a toothpick inserted into the center comes out clean. The cake should be golden brown and slightly firm to the touch.
- Allow the apple fritter cake to cool in the pan for about 10-15 minutes before serving.
