Ingredients

Scale

Dry Ingredients

  • 3 cups all-purpose flour
  • 1 ½ teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt

Wet Ingredients

  • 1 cup unsalted butter, softened
  • 1 ½ cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup buttermilk
  • Juice and zest of 2 lemons

Add-ins

  • 1 ½ cups blueberries (tossed with 1 tablespoon flour)

Glaze

  • Powdered sugar, for glaze
  • Lemon juice, for glaze


Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish and line it with parchment paper to ensure easy removal and even baking.
  2. Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set aside.
  3. Cream Butter and Sugar: Using a stand mixer, cream together the softened butter and granulated sugar until the mixture is light and fluffy, which usually takes about 3-5 minutes.
  4. Add Eggs and Vanilla: Add the eggs one at a time to the butter-sugar mixture, mixing well after each addition to ensure a smooth batter. Then mix in the vanilla extract and buttermilk until combined.
  5. Incorporate Dry Ingredients and Lemon: Gradually add the dry ingredient mixture to the wet ingredients, mixing just until combined to avoid overmixing. Fold in the juice and zest of 2 lemons for bright citrus flavor.
  6. Add Blueberries: Gently fold in the blueberries that have been tossed with 1 tablespoon of flour to prevent them from sinking in the batter.
  7. Bake: Pour the batter evenly into the prepared baking dish. Bake in the preheated oven for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean.
  8. Cool and Glaze: Allow the cake to cool completely in the pan. Mix powdered sugar with lemon juice to create a glaze, then drizzle it over the cooled cake for a sweet and tangy finish.

Notes

  • Coating the blueberries with flour helps keep them suspended in the batter so they don’t sink to the bottom.
  • Make sure the butter is softened to room temperature for easy creaming and better cake texture.
  • If buttermilk is unavailable, you can substitute by adding 1 tablespoon lemon juice or vinegar to 1 cup milk and letting it sit for 5 minutes.
  • Ensure the cake is completely cool before glazing to prevent the glaze from melting off.
  • Storage: Store leftover cake covered at room temperature for up to 2 days or refrigerate for up to a week.
