Instructions
Preheat oven to 350°F (175°C). Line a muffin tin with cupcake liners.
Make the crumble topping: Mix flour, brown sugar, cinnamon, and nutmeg in a bowl. Cut in butter until mixture resembles coarse crumbs. Refrigerate until needed.
Prepare the apple filling: Toss diced apples with sugar, lemon juice, cinnamon, nutmeg, and flour until evenly coated.
Make the cupcake batter: Whisk flour, baking powder, baking soda, and salt in a bowl. In another bowl, beat butter and sugar until light. Add eggs one at a time, then vanilla. Alternate adding dry ingredients with sour cream and milk.
Fill cupcake liners halfway with batter. Add a spoonful of apple filling to each, then top with remaining batter. Sprinkle crumble topping generously over each.
Bake for 18-22 minutes until a toothpick comes out clean. Cool in pan for 5 minutes, then transfer to a wire rack.
Notes
Store leftovers in an airtight container at room temperature for up to 2 days. For best texture, reheat briefly before serving.
