Ingredients

Scale

Dry Ingredients

  • 3 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1 1/4 teaspoon salt

Wet Ingredients

  • 1 cup butter (2 sticks), softened
  • 1 1/2 cups granulated sugar
  • Juice and zest of 2 lemons (about 1/4 cup lemon juice)
  • 4 large eggs
  • 1 cup buttermilk
  • 2 teaspoons vanilla extract

Fruits

  • 1 1/2 cups fresh blueberries, tossed with 1 tablespoon flour

Glaze

  • 2 1/2 cups powdered sugar
  • 1/3 cup lemon juice

Instructions

  1. Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and line it with parchment paper, leaving an overhang on the two longer sides to help remove the cake easily later.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
  3. Cream Butter and Sugar: Using a stand mixer with the paddle attachment or a hand mixer, beat the softened butter and granulated sugar together until the mixture is light and fluffy.
  4. Add Wet Ingredients: Add the eggs one at a time, then mix in vanilla extract and buttermilk on low speed until combined.
  5. Incorporate Dry Ingredients & Lemon: Gradually add the dry ingredient mixture, mixing until just combined and no flour streaks remain. Stir in the lemon juice and lemon zest for vibrant citrus flavor.
  6. Fold in Blueberries: Gently fold the blueberries, which have been tossed in flour to prevent sinking, into the batter with a spatula.
  7. Bake the Cake: Pour the batter evenly into the prepared pan. Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  8. Cool the Cake: Allow the cake to cool completely in the pan. Use the parchment paper overhang to lift it out easily if desired.
  9. Prepare and Add the Glaze: Mix together the powdered sugar and lemon juice until smooth. Pour the glaze evenly over the cooled cake and let it set until hardened.
  10. Serve: Garnish the glazed cake with fresh fruit if desired, slice, and enjoy!

Notes

  • Tossing blueberries with flour helps prevent them from sinking to the bottom of the cake during baking.
  • You can remove the cake from the pan before glazing for easier cutting and serving, or glaze it directly in the pan.
  • For a more intense lemon flavor, add extra lemon zest to the batter or glaze.
  • Ensure the cake is fully cooled before glazing to prevent the glaze from melting.
