A bright, buttery lemon pound cake bursting with juicy blueberries and finished with a tangy lemon glaze. Moist, tender, and perfect for brunch, dessert, or gifting.
Preheat oven to 350°F. Grease a 9 x 5 inch loaf pan and line it with a parchment sling for easy removal.
Toss the blueberries with 1.0 tablespoon flour to lightly coat; set aside.
In a large bowl, beat the softened butter, granulated sugar, and 2.0 tablespoon lemon zest on medium-high until pale and fluffy, about 3 minutes.
Beat in the eggs one at a time, mixing well and scraping the bowl after each addition.
In a separate bowl, whisk the 2.0 cup flour, baking powder, and salt until combined.
In a measuring cup, whisk sour cream, milk, vanilla, and lemon juice.
Add the dry ingredients to the butter mixture in 3 additions, alternating with the sour cream mixture, beginning and ending with dry. Mix on low just until combined; do not overmix.
Gently fold in the floured blueberries with a spatula.
Spread batter into the prepared pan and smooth the top. Bake 55 to 65 minutes, or until a toothpick inserted near the center comes out clean or with a few moist crumbs.
Cool in the pan for 15 minutes, then lift out and cool completely on a wire rack.
For the glaze, whisk powdered sugar with lemon juice, milk, and lemon zest until smooth and pourable. Adjust with a few drops of milk if needed.
Drizzle glaze over the cooled cake. Let set 10 minutes, slice, and serve.
Notes
For extra lift, ensure butter and eggs are truly at room temperature. Coating blueberries with a little flour helps prevent them from sinking. The cake tastes even better the next day—store covered at room temperature for up to 3 days.
