Ingredients

For the Cake:

  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 cup unsalted butter softened
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup sour cream
  • 2 medium apples peeled, cored, and diced

For the Crumb Topping:

  • 1/2 cup all-purpose flour
  • 1/4 cup granulated sugar
  • 1/4 cup brown sugar
  • 1 teaspoon ground cinnamon
  • 1/4 cup unsalted butter melted

For the Glaze (Optional):

  • 1/2 cup powdered sugar
  • 1 tablespoon milk
  • 1/2 teaspoon vanilla extract

Instructions

  • Preheat the oven to 350°F (175°C) and grease a 9-inch round or square baking pan.
  • Prepare the crumb topping by mixing flour, granulated sugar, brown sugar, and cinnamon in a small bowl. Stir in the melted butter until crumbs form. Set aside.
  • Make the cake batter: In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon.
  • In a large mixing bowl, beat the butter and sugar together until light and fluffy. Add the eggs one at a time, then stir in the vanilla extract.
  • Mix in the sour cream, followed by the dry ingredients, mixing until just combined. Fold in the diced apples.
  • Assemble the cake: Pour the batter into the prepared pan and smooth the top. Sprinkle the crumb topping evenly over the batter.
  • Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
  • Cool the cake in the pan for about 15 minutes before transferring it to a wire rack.
  • If using the glaze, whisk together powdered sugar, milk, and vanilla extract, then drizzle over the cooled cake.
  • Slice and enjoy!

Notes

  • Choose the right apples: Firm apples like Granny Smith, Honeycrisp, or Fuji work best as they hold their shape while baking.
  • Don’t overmix: Mix the batter just until combined to keep the cake soft and fluffy.
  • Use room temperature ingredients: This ensures a smooth and even batter.
  • Double the crumb topping: If you love extra crunch, make a little more of the streusel topping.
  • Make ahead: This cake stores well! Keep it covered at room temperature for up to 3 days or refrigerate for up to a week.
