For the cake
½ cup milk
1 tablespoon grated lemon zest, packed (I used 2 large lemons for zest and juice)
2 tablespoons fresh lemon juice
2 cups + 1 teaspoon all-purpose flour, spooned into measuring cup and leveled-off with a knife
¼ teaspoon baking soda
¼ teaspoon salt
1 cup fresh blueberries
1 stick unsalted butter, softened
1¼ cups granulated sugar
2 large eggs
FOR THE GLAZE
¾ cup confectioners’ sugar
¼ teaspoon lemon zest, packed
1½ tablespoons fresh lemon juice
Preheat the oven to 350°F. Spray a 9×5-inch metal loaf pan with nonstick cooking spray. Line the bottom of the pan with parchment paper, then spray the pan again.
In a small bowl, whisk together the milk, lemon zest, and lemon juice. Let sit for at least 10 minutes while you proceed with the recipe.
In a medium bowl, whisk together the 2 cups flour, baking soda, and salt. In a small bowl, toss the blueberries with the remaining teaspoon of flour. Set both aside. In mixing bowl add butter and sugar. With a hand mixer, beat on medium speed until light and fluffy, 2 to 3 minutes. Scrape down the sides of the bowl, then beat in the eggs one at a time, beating well after each addition. Scrape down the sides of the bowl again. With the mixer on low speed, beat in a third of the flour mixture, then half of the milk mixture. Beat in another third of the flour mixture, then the remaining milk mixture, followed by the remaining flour mixture, scraping the bowl as necessary. Add the flour-dusted blueberries to the batter and, using a spatula, fold until evenly combined. Transfer the batter into the prepared pan and smooth the top. Bake for 50 to 60 minutes, until the cake is golden brown and a toothpick comes out clean. Let the cake cool in the pan for about 10 minutes, then turn out onto a rack to cool completely. When the cake is cool, transfer it to a serving platter. Make the glaze: In a small bowl, mix together the confectioners’ sugar, lemon zest, and lemon juice. Add more confectioners’ sugar or lemon juice as necessary to make a thick but pourable glaze (about the consistency of molasses or honey). Spoon the glaze over the top of the cake, letting it drip down the sides. Let the glaze set for 10 to 15 minutes before serving.
