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
- Prep pans and oven. Preheat the oven to 180°C (350°F) and grease three six-inch round cake pans with parchment paper lining.
- Combine dry ingredients. Whisk flour, cornstarch, baking soda, baking powder, and salt in a bowl, reserving one tablespoon to coat the blueberries.
- 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.
- Add eggs and liquids. Incorporate eggs one at a time, then mix in the buttermilk and lemon juice until combined.
- Fold in dry ingredients. Gently fold the dry mixture into the wet ingredients in two batches using a rubber spatula just until combined.
- Coat and fold berries. Toss blueberries in the reserved flour mixture and gently fold them into the cake batter.
- Bake the cakes. Divide batter among the prepared pans and bake for 35 to 40 minutes, or until a toothpick comes out clean.
- Cool the layers. Let the cakes cool in the pans for ten minutes before transferring to a wire rack to cool completely.
- 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.
- 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.
