Ingredients
Scale
- 1 cup all-purpose flour
- 1 cup brown sugar
- 1/4 cup granulated sugar
- 2 tablespoons cinnamon
- 1/2 cup butter (1 stick), cold and cut into pieces
- 3/4 cup chopped walnuts
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup butter, room temperature
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 1/4 cups sour cream
Instructions
- Preparing the Oven and Pan: Preheat your oven to 350 degrees Fahrenheit. Grease a 9×9 inch baking dish with nonstick baking spray.
- Making the Streusel Topping: In a bowl, combine 1 cup all-purpose flour, 1 cup brown sugar, 1/4 cup granulated sugar, and 2 tablespoons cinnamon. Cut the 1/2 cup of cold butter into the dry ingredients using a pastry cutter until you achieve coarse crumbs. Fold in 3/4 cup chopped walnuts and set aside.
- Mixing the Coffee Cake Batter: In a separate bowl, whisk together 2 cups all-purpose flour, 1 teaspoon baking powder, 1 teaspoon baking soda, and 1/2 teaspoon salt. In a stand mixer fitted with a paddle attachment, cream together 1/2 cup butter and 1 cup granulated sugar until light and fluffy. Reduce the mixer’s speed to low and incorporate the eggs one at a time, followed by the vanilla extract. Alternately add the flour mixture and 1 1/4 cups sour cream in three parts, ensuring each addition is fully incorporated before proceeding.
- Assembling the Cake: Pour half of the coffee cake batter into the prepared baking dish, spreading evenly. Sprinkle half of the streusel topping over this layer. Carefully spread the remaining batter over the streusel before topping with the remaining streusel.
- Baking: Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
