Instructions

1. Preheat the oven to 350°F (175°C). Coat a 9×13-inch baking dish with butter and dust with 2 tablespoons of flour, ensuring complete coverage.
2. Whisk 2 ½ cups flour, 1 teaspoon baking powder, ½ teaspoon baking soda, and ½ teaspoon salt in a medium bowl until thoroughly combined.
3. Cream 1 cup softened butter with 1 ½ cups granulated sugar using an electric mixer for 3-4 minutes until light and fluffy.
4. Add 3 large eggs one at a time to the butter mixture, blending completely after each addition. Mix in 2 teaspoons vanilla extract, zest from 2 lemons, and ¼ cup fresh lemon juice.
5. Gradually incorporate the dry ingredients and 1 cup buttermilk into the wet mixture, alternating between them. Mix until just combined, avoiding overmixing.
6. Gently fold 1 ½ cups blueberries into the batter, ensuring they are evenly distributed without breaking.
7. Transfer the batter to the prepared baking dish, spreading it evenly with a spatula. Tap the dish on the counter to release any air bubbles.
8. Bake at 350°F (175°C) for 35-40 minutes. Check doneness by inserting a toothpick into the center – it should come out clean with no wet batter.
9. Remove the cake from the oven and let it cool in the dish for 15 minutes. Transfer to a wire rack to cool completely.
10. Prepare the glaze by whisking 1 cup powdered sugar with 2-3 tablespoons fresh lemon juice and zest from 1 lemon until smooth.
11. Drizzle the glaze over the completely cooled cake, allowing it to run naturally across the surface.
12. Cut into squares and serve at room temperature. Store any remaining cake covered at room temperature for up to 3 days.

Notes

• Check blueberries for ripeness and gently fold them into the batter to prevent breaking and maintain even distribution throughout the cake.
• Use room temperature ingredients like eggs and buttermilk to ensure smoother batter mixing and more consistent cake texture.
• For a gluten-free version, substitute all-purpose flour with a high-quality gluten-free flour blend and add 1 teaspoon of xanthan gum for better structure.
• Zest the lemon before juicing to maximize flavor and ensure bright, fresh citrus notes in both the cake and glaze.
