Method
Preheat Oven
- Preheat oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan or line with parchment paper.
Make the Cake Batter
- In a bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg. In a separate large bowl, cream butter and sugar until fluffy. Add eggs one at a time, then stir in vanilla. Mix in sour cream until smooth. Gradually fold in dry ingredients until just combined. Gently fold in diced apples.
Prepare the Crumb Topping
- In a small bowl, combine flour, brown sugar, granulated sugar, and cinnamon. Cut in cold butter with a fork or pastry cutter until crumbly.
Assemble and Bake
- Spread cake batter evenly in the prepared pan. Sprinkle crumb topping evenly over the batter. Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
Cool and Serve
- Allow cake to cool in the pan for at least 15 minutes before slicing. Serve warm or at room temperature. Optional: drizzle with caramel sauce for extra indulgence.
Notes
Apple tips: Use firm apples like Honeycrisp, Granny Smith, or Fuji for best texture.
Make ahead: Cake can be stored in an airtight container at room temperature for 2–3 days or refrigerated for up to 5 days.
Add-ins: Walnuts or pecans in the crumb topping add extra crunch and flavor.
