Ingredients

Scale
  • 2 large apples, peeled, cored, and diced (about 2 cups)
  • 1 ½ cups all-purpose flour, divided
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • ½ cup unsalted butter, softened (divided into 1/4 cup portions)
  • 1 cup granulated sugar, divided
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup sour cream or plain yogurt (full-fat works best)
  • ¾ cup all-purpose flour (for crumb topping)
  • ¾ cup packed light brown sugar (for crumb topping)
  • ¼ teaspoon ground cinnamon (for crumb topping)
  • ¼ teaspoon salt (for crumb topping)
  • 6 tablespoons cold unsalted butter, cut into small pieces (for crumb topping)

Instructions

  • Preheat your oven to 350°F (175°C). Grease and flour a 9-inch square baking pan or line it with parchment paper.
  • Prepare the crumb topping: Mix flour, brown sugar, cinnamon, and salt in a medium bowl. Add cold butter pieces and rub with fingers or pastry cutter until coarse crumbs form. Chill in fridge.
  • Mix dry ingredients for the cake: whisk together 1 cup flour, baking powder, baking soda, cinnamon, and salt in another bowl.
  • Cream butter and sugar: Beat 1/4 cup softened butter with 1/2 cup granulated sugar until light and fluffy (about 3 minutes).
  • Add eggs and vanilla: Beat in eggs one at a time then stir in vanilla extract.
  • Add sour cream: Mix in sour cream until smooth.
  • Combine wet and dry ingredients: Gradually add dry flour mixture to wet ingredients, stirring until just combined.
  • Fold in diced apples gently, avoiding overmixing.
  • Pour batter into prepared pan and spread evenly.
  • Sprinkle chilled crumb topping evenly over batter without pressing down.
  • Bake for 40–45 minutes until a toothpick comes out with a few moist crumbs and crumb topping is golden.
  • Cool completely in pan on a wire rack for at least 20 minutes before slicing.
