Method
Step-by-Step
- Preheat the oven to 350°F (175°C). Thoroughly grease every groove of a 10- to 12-cup Bundt pan, then dust it lightly with flour or coat it with baking-release spray.
- Whisk together 2 3/4 cups of the flour, baking powder, baking soda, and salt in a medium bowl. Toss the blueberries with the remaining 1/4 cup flour in a separate bowl.
- Beat the softened butter and granulated sugar on medium speed for 3–5 minutes, until pale and fluffy. Scrape the bowl so the butter mixture is evenly aerated.
- Beat in the eggs one at a time, scraping down the sides of the bowl as needed. Mix in the lemon zest, lemon juice, and vanilla extract.
- Add the dry ingredients in three additions, alternating with the sour cream. Begin and end with the dry ingredients, mixing only until the batter is combined.
- Gently fold the floured blueberries into the batter. Use a light hand so the berries stay intact and do not release too much juice.
- Spoon the batter evenly into the prepared Bundt pan and smooth the top. Bake for 55–65 minutes, until a skewer inserted into the thickest part comes out clean or with a few moist crumbs.
- Cool the cake in the pan for 15–20 minutes. Invert it onto a wire rack and let it cool completely, which takes about 1 hour, before adding the glaze.
- Whisk the confectioners' sugar with 2 tablespoons lemon juice. Add more lemon juice a few drops at a time until the glaze is thick but pourable, then drizzle it over the cooled cake.
Notes
Use room-temperature butter, eggs, and sour cream for a properly mixed, tender batter. Fresh blueberries are preferred, but frozen blueberries may be folded in without thawing; expect some slight streaking. Let the cake cool about 15–20 minutes before turning it out, then cool completely before glazing.
