What You’ll Need

Gather These Simple Ingredients:

  • 3 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1 1/4 teaspoon salt
  • 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
  • 1 1/2 cups fresh blueberries, tossed with 1 tablespoon flour
  • 2 1/2 cups powdered sugar
  • 1/3 cup lemon juice

Let’s Make It Together

Step-by-Step Instructions:

  1. Preheat the oven to 350 degrees F. Grease a 9×13 baking dish and line it with parchment paper, leaving an overhang on the long sides of the pan for easy removal.

  2. In a medium mixing bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

  3. In a stand mixer fitted with the paddle attachment (or a hand mixer), cream together the softened butter and granulated sugar until light and fluffy.

  4. Add in the eggs, buttermilk, and vanilla extract. Mix on low speed until everything is well incorporated.

  5. Gradually add the dry ingredients to the wet mixture, mixing until no streaks of flour remain. Be careful not to overmix – it’s okay if you still see a few lumps.

  6. Mix in the lemon juice and zest until fully combined.

  7. Gently fold in the blueberries with a spatula, taking care not to break them.

  8. Pour the batter into the prepared baking dish and spread it evenly.

  9. Bake in the preheated oven for 40-45 minutes or until a toothpick inserted in the center comes out with moist crumbs.

  10. Allow the cake to cool completely. You can lift it out of the pan before drizzling the glaze or leave it in the dish to serve – it’s your choice!

  11. For the glaze, combine the powdered sugar with the lemon juice and stir until smooth. Drizzle over the cooled cake and let it harden for a bit.

  12. Garnish with fresh fruit if desired, and then slice into squares and serve. Enjoy with a warm cup of tea or coffee!

Delicious Variations to Try

  1. Berry Medley: Replace or mix the blueberries with fresh raspberries or strawberries for an even sweeter treat bursting with color.

  2. Lemon Zest Frosting: Instead of a glaze, whip up a creamy lemon frosting by adding cream cheese to the powdered sugar and lemon juice mixture for a rich twist.

  3. Nutty Addition: Toss in chopped walnuts or pecans for a lovely crunch and to create a more rustic, hearty feel.

  4. Coconut Bliss: Sprinkle shredded coconut over the top for an indulgent tropical flavor that pairs beautifully with lemon.

Chef Emma’s Helpful Tips

  1. Make-Ahead Tips: This cake can be made a day in advance. Just store it covered at room temperature, and add the glaze just before serving for the freshest taste.

  4. Storage Suggestions: Leftovers can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. You can also freeze the cake for up to three months—just thaw before enjoying!
