Ingredients
For the Cake:
- 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 (toss frozen blueberries with 1 tablespoon flour)
For the Topping:
- 1/2 cup brown sugar
- 1 teaspoon ground cinnamon
- 3/4 cup chopped walnuts
For Garnish:
- Powdered sugar, for dusting
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350℉ (177℃). 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 with granulated sugar until the mixture becomes light and fluffy, about 2 to 3 minutes.
- Add Eggs, Sour Cream, and Vanilla: Add the eggs one at a time, beating well after each addition to fully incorporate. Scrape down the sides and bottom of the bowl, then mix in the sour cream and vanilla extract until combined.
- Mix 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 and mix just until blended; avoid overmixing to keep the cake tender.
- Fold in Blueberries: Gently fold the fresh or floured frozen blueberries into the batter to evenly distribute them without breaking the berries.
- Assemble Cake Layers: Generously grease and flour the Bundt pan again if needed. Spoon half of the batter into the pan, spreading it evenly.
- Add Topping Layer: In a small bowl, combine brown sugar, ground cinnamon, and chopped walnuts. Sprinkle this mixture evenly over the batter in the pan.
- Top with Remaining Batter: Spoon the remaining batter over the brown sugar walnut layer and smooth the surface carefully.
- Bake: Place the Bundt pan in the preheated oven and bake for 55 to 70 minutes. Check doneness by inserting a knife or long skewer into the center; it should come out clean or with a few crumbs.
- Cool and Serve: Allow the cake to cool in the pan for 10 minutes. Then invert the pan onto a serving plate. If the cake doesn’t release immediately, tap the pan firmly with the end of a knife to loosen it. Let the cake cool completely or serve slightly warm, dusting with powdered sugar just before serving.
Notes
- You can use frozen blueberries directly from the freezer by tossing them in a tablespoon of flour to prevent bleeding into the batter.
- This cake is delicious served warm or at room temperature.
- To store, wrap the cake tightly and keep it at room temperature for up to 2 days or refrigerate for up to 5 days.
- For a nut-free version, omit the walnuts or substitute with your favorite seeds.
