Ingredients

Scale
  • 2 ½ cups (315 g) all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 ¾ cups (350 g) granulated sugar
  • ¾ cup (170 g) unsalted butter, softened
  • 3 large eggs, room temperature
  • 1 cup (240 ml) buttermilk, room temperature
  • Zest of 2 fresh lemons
  • ¼ cup (60 ml) fresh lemon juice
  • 1 teaspoon vanilla extract
  • 1 ½ cups (225 g) frozen blueberries, thawed and drained
  • 2 cups (240 g) powdered sugar
  • 2–3 tablespoons milk or lemon juice (for glaze)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or line with parchment paper.
  2. In a large bowl, sift together flour, baking powder, baking soda, and salt. Set aside.
  3. Using an electric mixer, beat softened butter and granulated sugar on medium speed until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, then mix in lemon zest and vanilla extract.
  5. Add dry ingredients in three additions alternating with buttermilk, starting and ending with flour mixture. Mix on low speed just until combined.
  6. Gently fold in thawed blueberries with a spatula, being careful not to crush them.
  7. Spread batter evenly in prepared pan.
  8. Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Cool in pan on wire rack for about 20 minutes, then remove cake from pan and cool completely.
  10. Whisk powdered sugar with lemon juice or milk until smooth and pourable to make glaze.
  11. Drizzle glaze over cooled cake and let set for 15-20 minutes before serving.

Notes

Do not overmix the batter after adding flour and buttermilk to avoid a tough crumb. Fold blueberries gently to prevent batter from turning purple. Use room temperature ingredients for best results. Tent cake with foil if browning too fast. Let cake cool completely before glazing.
