Ingredients

Scale
  • 1 cup (230g) unsalted butter, softened
  • 1 and 1/4 cups (250g) granulated sugar
  • 1/2 cup (100g) brown sugar
  • 4 large eggs, at room temperature
  • 1 tablespoon lemon zest (about 2 lemons)
  • 1/4 cup (60ml) fresh lemon juice
  • 1 teaspoon vanilla extract
  • 3 cups (375g) all-purpose flour
  • 1 tablespoon baking powder
  • 1/2 teaspoon salt
  • 1 cup (240ml) buttermilk, at room temperature
  • 2 cups (300g) fresh or frozen blueberries
  • 1 tablespoon flour (for tossing blueberries)
  • Powdered sugar or lemon glaze for topping (optional)

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or two 8-inch round cake pans.
  2. In a large bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy.
  3. Add the eggs one at a time, beating well after each addition. Stir in the lemon zest, lemon juice, and vanilla extract.
  4. In a separate bowl, whisk together the flour, baking powder, and salt.
  5. Alternately add the dry ingredients and the buttermilk to the wet ingredients, beginning and ending with the flour mixture. Mix until just combined.
  6. Toss the blueberries with 1 tablespoon of flour and gently fold them into the batter.
  7. Pour the batter into the prepared pan(s) and smooth the top.
  8. Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
  9. Let the cake cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.
  10. Top with powdered sugar or lemon glaze, if desired, before serving.

Notes

  • If using frozen blueberries, do not thaw before adding to the batter.
  • Cake can be stored in an airtight container at room temperature for up to 3 days.
  • Optional lemon glaze: Mix 1 cup powdered sugar with 2-3 tablespoons lemon juice until smooth.
