Instructions
 

Preparation

  • Preheat your oven to 350°F. Prepare a 9x13-inch baking dish by greasing or lining it with parchment paper.
  • In a large mixing bowl, whisk together the cake flour, baking powder, baking soda, and salt.
  • In another bowl, combine buttermilk, lemon juice, and lemon zest. Stir gently until blended.
  • In a separate bowl, cream the softened butter and granulated sugar until light and fluffy.
  • Add the vanilla extract and eggs one at a time, beating well after each addition.
  • Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk mixture. Mix just until combined.
  • Gently fold in the blueberries.

Baking

  • Pour the batter into the prepared baking dish and smooth the top.
  • Bake for 25-30 minutes until golden brown and a toothpick inserted comes out clean.
  • Allow the cake to cool in the dish for 15 minutes before transferring to a wire rack to cool completely.

Frosting

  • Beat the cream cheese and softened butter until smooth. Gradually add sifted powdered sugar until desired consistency is reached, then blend in lemon juice.
  • Once the cake is cool, frost the top generously with the cream cheese frosting.

Notes

For best results, ensure all ingredients are at room temperature. Avoid overmixing to maintain cake tenderness. Any leftovers can be stored in an airtight container.
