Entenmanns Apple Crumb Cake

Instructions

1. Preheat your oven to 350°F (175°C) and grease a 9x9-inch baking dish.

2. In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt.

3. Add the cold butter cubes to the flour mixture and use a pastry cutter or your fingers to cut the butter into the flour until the mixture resembles coarse crumbs.

4. In a separate bowl, whisk together the egg, sour cream, and vanilla extract until smooth.

5. Pour the wet ingredients into the flour mixture and stir until just combined.

6. Gently fold in the diced apples until evenly distributed throughout the batter.

7. In a small bowl, mix the brown sugar and cinnamon to create the crumb topping.

8. Pour half of the batter into the prepared baking dish and spread it out evenly.

9. Sprinkle half of the crumb topping over the batter.

10. Carefully spread the remaining batter over the crumb topping.

11. Top the cake with the rest of the crumb mixture, ensuring an even layer.

12. Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean.

13. Allow the cake to cool slightly before slicing and serving.
