Ingredients
Cake Batter
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 1 cup sour cream, at room temperature
- 2 large eggs, at room temperature
- 1 teaspoon vanilla extract
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
Streusel Topping
- 1 cup light brown sugar, packed
- 1 cup all-purpose flour
- 1/2 cup unsalted butter, melted
- 1 tablespoon ground cinnamon
- 1/2 cup chopped walnuts or pecans (optional)
Vanilla Glaze (Optional)
- 1 cup powdered sugar
- 2 tablespoons milk or cream
- 1/2 teaspoon vanilla extract
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or line it with parchment paper to prevent sticking.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this mixture aside for later.
- Cream Butter and Sugar: In a large bowl, cream the softened butter and granulated sugar until the mixture is light and fluffy, which usually takes about 3 to 4 minutes using an electric mixer.
- Add Eggs and Vanilla: Beat the eggs into the creamed butter mixture one at a time, ensuring each egg is fully incorporated before adding the next. Then stir in the vanilla extract.
- Combine Batter: Gradually add the dry flour mixture to the butter mixture, alternating with the sour cream. Begin and end with the dry ingredients, mixing until just combined to avoid overmixing.
- Prepare Streusel Topping: In a separate bowl, combine the brown sugar, flour, and ground cinnamon. Stir in the melted butter and chopped nuts if using, mixing until you form a crumbly texture.
- Assemble Cake: Spread half of the cake batter evenly in the prepared baking pan. Sprinkle half of the streusel topping evenly over the batter. Repeat with the remaining batter and streusel, layering carefully.
- Bake: Place the pan in the preheated oven and bake for 35 to 40 minutes, or until a toothpick inserted into the center of the cake comes out clean.
- Cool and Glaze: Remove the cake from the oven and cool it in the pan on a wire rack. If desired, whisk together powdered sugar, milk or cream, and vanilla extract to create a glaze and drizzle it over the cooled cake before serving.
Notes
- For a nut-free version, omit the nuts in the streusel topping.
- Room temperature ingredients help the batter blend together smoothly and create a tender crumb.
- If you prefer a stronger cinnamon flavor, increase the cinnamon in the streusel slightly.
- The glaze is optional but adds a lovely sweetness and finish to the cake.
- Store leftovers covered at room temperature for up to 3 days or refrigerate for up to a week.
