1. Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
2. In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, salt, and cinnamon.
3. In another bowl, beat the eggs and mix in the melted butter, vanilla extract, and sour cream until smooth.
4. Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Don’t worry if the batter is a bit lumpy—that’s part of the charm!
5. Fold in the sliced apples and, if using, the chopped nuts and raisins. This is where you can involve the kids, letting them sprinkle in the extras like little kitchen elves.
6. Pour the batter into the prepared cake pan and spread it evenly.
7. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean. The aroma will remind you of those warm family gatherings, even if you’re just feeding the kids on a Wednesday night.
8. Let the cake cool in the pan for about 10 minutes before transferring to a wire rack to cool completely.

And there you have it—a cake that’s simple, scrumptious, and steeped in tradition.
