Ingredients
Scale
Cake Batter
- 3/4 cup (170g) salted butter, softened
- 1 3/4 cups (350g) granulated sugar
- 2 large eggs, room temperature
- 1 cup (240g) sour cream, room temperature
- 1 teaspoon pure vanilla extract
- 1 2/3 cups (234g) all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 2 cups fresh or frozen blueberries
Brown Sugar Walnut Layer
- 1/2 cup brown sugar
- 1 teaspoon ground cinnamon
- 3/4 cup chopped walnuts
For Serving
- Powdered sugar for dusting
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch (10-cup) Bundt pan thoroughly to prevent sticking.
- Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together using a hand or stand mixer until the mixture becomes light and fluffy, about 2 to 3 minutes.
- Add Eggs and Wet Ingredients: Add eggs one at a time, beating well after each addition. Scrape down the sides and bottom of the bowl, then mix in the sour cream and vanilla extract until fully combined.
- Add Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add these dry ingredients to the wet mixture, mixing just until blended. Avoid overmixing to keep the cake tender.
- Fold in Blueberries: Gently fold in the blueberries. If using frozen blueberries, toss them with 1 tablespoon of flour first to prevent them from sinking.
- Layer Batter and Topping: Spoon half of the cake batter into the prepared Bundt pan. In a small bowl, combine the brown sugar, ground cinnamon, and chopped walnuts. Sprinkle this mixture evenly over the batter in the pan. Top with the remaining batter and smooth the surface.
- Bake: Bake in the preheated oven for 55 to 70 minutes, or until a knife or long skewer inserted into the center of the cake comes out clean or with just a few crumbs attached.
- Cool and Serve: Allow the cake to cool in the pan for about 10 minutes. Then carefully invert the Bundt pan onto a serving plate. If it does not release easily, tap the pan firmly a few times with the butt end of a knife to loosen it. Let it cool completely, then dust with powdered sugar just before serving. This coffee cake is delightful served slightly warm or fully cooled.
Notes
- Variations: Substitute blueberries with blackberries, raspberries, huckleberries, cherries, or strawberries for different fruit flavors.
- Nut Alternatives: Use pecans or pistachios instead of walnuts as preferred.
- Substitutions: Greek yogurt or buttermilk can be used in equal amounts instead of sour cream for a slight variation in texture and flavor.
- Ensure all wet ingredients like eggs and sour cream are at room temperature for best results.
- For frozen blueberries, tossing with flour prevents sinking and color bleeding into the batter.
