Ingredients

Scale
  • For the Cake: 1 3/4 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup milk
  • 3 medium apples (like Granny Smith or Honeycrisp), peeled, cored, and diced
  • 1 teaspoon ground cinnamon (for apples)
  • For the Crumb Topping: 1 1/2 cups all-purpose flour
  • 1/2 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 1 teaspoon ground cinnamon
  • 1/2 cup (1 stick) cold unsalted butter, cut into small pieces
  • For the Cinnamon Drizzle (Optional): 1 cup powdered sugar
  • 2 tablespoons milk
  • 1/2 teaspoon ground cinnamon

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9-inch square baking pan.
  2. Prepare the apples: In a small bowl, toss the diced apples with 1 teaspoon of ground cinnamon. Set aside.
  3. Make the cake batter: In a medium bowl, whisk together 1 3/4 cups flour, baking powder, and salt. Set aside.
  4. In a large bowl, beat the softened butter and 1 cup of granulated sugar with an electric mixer until light and fluffy. Beat in the eggs one at a time, then mix in the vanilla extract.
  5. Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry mixture. Mix until just combined; do not overmix.
  6. Make the crumb topping: In a separate bowl, combine 1 1/2 cups flour, brown sugar, 1/4 cup granulated sugar, and 1 teaspoon cinnamon. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  7. Assemble the cake: Spread half of the cake batter into the prepared pan. Sprinkle the cinnamon apples evenly over the batter. Top with half of the crumb mixture. Gently spread the remaining cake batter over the crumbs. Top with the remaining crumb mixture.
  8. Bake for 45 to 55 minutes, or until a wooden skewer inserted into the center comes out clean.
  9. Cool the cake in the pan for 15 minutes before removing it to a wire rack to cool completely.
  10. Prepare the drizzle (if using): Whisk together the powdered sugar, 2 tablespoons milk, and 1/2 teaspoon cinnamon until smooth. Drizzle over the cooled cake.

Notes

  • For the best texture, use room temperature ingredients for the cake batter, except for the butter in the crumb topping, which must be cold.
  • If you prefer a thicker crumb layer, increase the crumb topping ingredients by 50% and use a 9×9 inch pan.
  • This cake keeps well covered at room temperature for up to three days.
