Description

Experience bakery-quality results with this three-layer lemon blueberry cake, featuring an ultra-tender crumb thanks to a touch of cornstarch. The whipped cream cheese frosting creates a light, cloud-like finish that perfectly balances the bright citrus and juicy berry notes.


Ingredients

  • 2 1/2 cups all-purpose flour
  • 2 tbsp cornstarch
  • 1 tsp baking soda
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1/2 cup softened butter
  • 1/4 cup vegetable oil
  • 1 1/2 cups granulated sugar
  • 1 tbsp fresh lemon zest
  • 3 large eggs
  • 1 cup buttermilk
  • 2 tbsp fresh lemon juice
  • 1 1/2 cups fresh blueberries
  • 8 oz cream cheese, chilled
  • 1 cup heavy cream, chilled
  • 1/2 cup powdered sugar
  • 1 tsp vanilla extract


Instructions

  1. Prep pans and oven. Preheat the oven to 180°C (350°F) and grease three six-inch round cake pans with parchment paper lining.
  2. Combine dry ingredients. Whisk flour, cornstarch, baking soda, baking powder, and salt in a bowl, reserving one tablespoon to coat the blueberries.
  3. Cream butter and sugar. Beat butter, oil, sugar, and lemon zest in a large bowl on medium speed for three minutes until pale and fluffy.
  4. Add eggs and liquids. Incorporate eggs one at a time, then mix in the buttermilk and lemon juice until combined.
  5. Fold in dry ingredients. Gently fold the dry mixture into the wet ingredients in two batches using a rubber spatula just until combined.
  6. Coat and fold berries. Toss blueberries in the reserved flour mixture and gently fold them into the cake batter.
  7. Bake the cakes. Divide batter among the prepared pans and bake for 35 to 40 minutes, or until a toothpick comes out clean.
  8. Cool the layers. Let the cakes cool in the pans for ten minutes before transferring to a wire rack to cool completely.
  9. Prepare the frosting. Beat cream cheese until smooth, whip heavy cream with sugar and vanilla in a separate bowl, then fold everything together until fluffy.
  10. Assemble the cake. Level the cooled cake layers, stack with alternating layers of frosting, and finish by covering the top and sides before chilling.

Notes

  • Ensure all dairy components like cream cheese and heavy cream remain cold to guarantee the frosting holds a stable, fluffy structure.
  • Coating the blueberries in a small portion of flour is essential to keep them suspended within the batter rather than sinking during the bake.
  • Using light-colored aluminum pans prevents the edges from setting too quickly, which helps avoid domed centers and dry cake edges.
  • Grate only the bright yellow portion of the lemon skin to avoid incorporating bitter white pith into your cake batter.
  • Rest the frosted cake in the refrigerator for at least thirty minutes to allow the layers to set for clean, beautiful slices.
