Ingredients
Scale
- 2 cups and 1 cup all-purpose flour
- 1 cup brown sugar
- 1 cup granulated sugar
- ¼ cup granulated sugar
- ½ cup butter, room temperature
- ½ cup butter (1 stick), cold and cut into pieces
- 2 large eggs
- 1 ¼ cups sour cream
- ¾ cup chopped walnuts
- 2 tbsps cinnamon
- 1 tsp vanilla extract
- 1 tsp baking soda
- 1 tsp baking powder
- ½ tsp salt
Instructions
- Streusel Preparation: Combine flour, brown sugar, granulated sugar, and cinnamon in a mixing bowl. Cut cold butter into the dry ingredients until the mixture resembles coarse crumbs, then fold in chopped walnuts and set aside.
- Dry Ingredient Blend: Sift flour, baking powder, baking soda, and salt together, creating a uniform dry mixture that will provide structure to the cake.
- Butter Mixture: Cream butter and granulated sugar in a stand mixer until light and fluffy. Incorporate eggs one at a time, blending thoroughly after each addition, and mix in vanilla extract for depth of flavor.
- Batter Formation: Gently fold the dry ingredient mixture and sour cream into the butter base, alternating to maintain the batter’s delicate consistency and prevent overmixing.
- Pan Preparation: Thoroughly coat a 9×9 inch baking dish with nonstick spray, ensuring complete coverage to prevent sticking.
- Layering Process: Spread half the cake batter evenly in the prepared pan, create a generous streusel layer across the first batter layer, then carefully cover with remaining batter and top with the final streusel layer, distributing walnuts and spices evenly.
- Baking: Position the cake in a preheated 350°F oven and bake for 35-40 minutes. Check for doneness by inserting a toothpick into the center – it should come out clean, indicating the cake is fully cooked.
Notes
- Measure Precisely: Use exact measurements for consistent cake texture and flavor, especially with baking powder and sour cream.
- Room Temperature Matters: Ensure butter, eggs, and sour cream are at room temperature to create a smoother, more uniform batter.
- Gentle Mixing Technique: Fold ingredients gently to prevent overmixing, which can lead to a dense, tough cake texture.
- Streusel Distribution: Spread streusel evenly between layers and on top for a balanced crunch and cinnamon flavor in every bite.
