  4. Add the eggs, one at a time, mixing well after each addition. Mix in the vanilla extract and sour cream until smooth.
  5. Gradually add the dry ingredients to the wet mixture, stirring gently until just combined.
  6. Fold in the diced apples until evenly distributed.
  7. Pour the batter into the prepared baking dish and spread it evenly.
Crumb Topping
  1. In a separate bowl, mix together the flour, brown sugar, cinnamon, and salt. Stir in the melted butter until crumbly.
  2. Sprinkle the crumb topping evenly over the batter.
Baking
