• Preheat oven to 350°F

Crumb Topping

• Create the streusel, or crumb topping by combining the butter, brown sugar, flour, cinnamon, and nutmeg. Set aside.
  ⅔ cup flour, ½ cup brown sugar, 1 teaspoon cinnamon, ⅛ teaspoon nutmeg, 4 tablespoons butter

Filling

• Peel, core, and dice the apples into small ½ cubes. Toss with brown sugar, flour, cinnamon, and nutmeg. Set aside.
  1 ½ cups diced apples, ¼ cup brown sugar, 1 tablespoon flour, 1 teaspoon cinnamon, ⅛ teaspoon nutmeg

Coffee Cake

• Make the cake batter by combining the milk, melted butter, sugar, egg, and vanilla in a large bowl.
  ½ cup milk, ⅓ cup butter, 1 egg, 2 teaspoons vanilla, ¾ cup granulated sugar
• Add flour on top of the batter and then sprinkle with baking powder, salt, and cinnamon.
  2 cups flour, 2 teaspoons baking powder, ½ teaspoon salt, ½ teaspoon cinnamon
• Begin mixing the baking powder, salt, and cinnamon into the flour first, and then mix everything into the batter. Stir just until combined.
• Place half of the cake batter in a lightly greased 8x8-inch baking dish. Spread batter as evenly as possible. The batter layer will be fairly thin. Use a spatula to gently spread it all the way to the edges of the pan before adding the apples.
• Add prepared apples evenly over the batter. Add the remaining cake batter and spread it as evenly as possible.
• Crumble the streusel topping over the top. I use my hands to crumble the topping over the cake.
• Bake in a preheated 350°F oven for 40-50 minutes.
• Cool before serving.
