Method
Prepare and preheat
- Preheat the oven to 350°F and grease a 10-cup Bundt pan thoroughly with butter or nonstick spray; dust lightly with flour and tap out excess.
Dry ingredients
- In a medium bowl whisk together 2 cups all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt.
Creaming
- In a large bowl, beat 1 cup unsalted butter and 1 1/2 cups granulated sugar until light and slightly fluffy, about 3 to 4 minutes; beat in 3 eggs one at a time, then stir in lemon zest and 2 teaspoons vanilla.
Combine batter
- With the mixer on low, add the dry ingredients in three additions alternating with 1 cup sour cream, beginning and ending with the flour; mix until just combined.
Blueberries
- Toss 2 cups blueberries with 1 tablespoon flour and 1 teaspoon sugar, then fold gently into the batter with a spatula.
Bake
- Scrape batter into the prepared pan and bake at 350°F for 45 to 55 minutes, until a skewer inserted near center comes out with a few moist crumbs; start checking at 40 minutes.
Cool and unmold
- Cool cake in pan on a wire rack for 15 minutes, invert to release, then cool completely for about 60 minutes before glazing.
Glaze
- Whisk 1 1/2 cups powdered sugar with 2 tablespoons lemon juice and 1 tablespoon milk until pourable; adjust with more powdered sugar or lemon juice to reach desired consistency, then drizzle over cooled cake and garnish if desired.
Notes
Use full-fat sour cream for best texture; if using frozen blueberries, toss them frozen with extra flour and expect a slight increase in bake time. Grease and flour the Bundt pan well to prevent sticking and cool the cake before glazing to avoid glaze soaking in.
