# Ingredients:

Batter

01 - 2 cups all-purpose flour
02 - 1 cup granulated sugar
03 - 1/2 cup unsalted butter, softened
04 - 1 cup sour cream
05 - 2 large eggs
06 - 1 teaspoon baking powder
07 - 1/2 teaspoon baking soda
08 - 1/4 teaspoon salt
09 - 1 teaspoon vanilla extract
10 - 1 cup apple pie filling
11 - 1/2 cup chopped walnuts (optional)

Crumb Topping

12 - 1/2 cup brown sugar
13 - 1/4 cup all-purpose flour
14 - 1/4 cup unsalted butter, cold and cubed
15 - 1 teaspoon ground cinnamon

# Instructions:

01 - Preheat the oven to 350°F (175°C). Grease and flour a 9-inch square baking pan.
02 - In a medium bowl, whisk together all-purpose flour, baking powder, baking soda, and salt.
03 - In a large bowl, cream the softened butter and granulated sugar until light and fluffy.
04 - Beat in the eggs one at a time, followed by the vanilla extract.
05 - Alternately add the dry ingredients and sour cream to the butter mixture, beginning and ending with the dry ingredients. Mix until just combined.
06 - Pour half of the batter into the prepared pan, spreading evenly. Spoon apple pie filling over the batter, then sprinkle with chopped walnuts if desired.
07 - Spread the remaining batter carefully over the apple pie filling to cover it completely.
08 - In a small bowl, combine brown sugar, all-purpose flour, cubed cold butter, and ground cinnamon using a fork until crumbly.
09 - Sprinkle the crumb mixture evenly over the top of the batter layer.
10 - Bake for 45 to 50 minutes, or until a toothpick inserted in the center comes out clean.
11 - Allow the coffee cake to cool in the pan for 15 minutes before transferring to a wire rack to cool completely.

# Notes:

01 - For best texture, avoid overmixing the batter once dry ingredients are combined.
