Lemon Blueberry Cake
1 cup butter, softened to room temperature
1 3/4 cups granulated sugar
1 tablespoon fresh lemon zest
4 large eggs, room temperature
2 teaspoons vanilla extract
2 1/2 cups all-purpose flour
2 teaspoons baking powder
1/4 teaspoon baking soda
1/2 teaspoon salt
1 cup buttermilk
1/2 cup fresh lemon juice (from about 3 lemons)
2 cups (12 ounces) fresh or frozen blueberries (do not thaw if frozen)
2 tablespoons all-purpose flour
Whipped Lemon Cream Frosting
12 ounces cream cheese, softened to room temperature
1/2 cup butter, softened to room temperature
4 1/2 cups powdered sugar
1 to 2 teaspoons fresh lemon zest
1 tablespoon fresh lemon juice
2 tablespoons heavy cream
Directions:
- Preheat the oven to 350 degrees. Line the bottom of two 9-inch round cake pans with at least 2-inch sides, or three 8-inch round cake pans, with parchment paper and coat with nonstick cooking spray. Set aside.
- In the bowl of an electric mixer fitted with the paddle attachment, cream together the butter, sugar, and lemon zest until light and fluffy, 4-5 minutes.
- Add the eggs and vanilla until well-combined, 1-2 minutes, scraping down the sides of the bowl as needed.
- In a separate bowl, whisk together the flour, baking powder, soda and salt. Stir the dry mixture into the wet ingredients and mix on low speed until just combined and a few dry streaks remain.
- Add the buttermilk and lemon juice to the batter, and stir by hand, folding the batter until just combined.
- In another bowl, toss the blueberries with the 2 tablespoons flour. Add the blueberries and remnants of flour to the batter and fold in by hand with a spatula or wooden spoon until just-combined. Overmixing may result in a tough, dry cake.
- Spread the batter evenly in the prepared pans and bake for 35-40 minutes until just baked through. The top will spring back lightly to the touch and a toothpick inserted in the center should come out with moist crumbs but not wet batter.
- Let the cakes cool for 5-10 minutes in the pans before turning them out onto a cooling rack to cool completely.
- For the frosting, whip the cream cheese and butter together with a handheld electric mixer or with an electric stand mixer fitted with the paddle attachment until light and fluffy, 2-3 minutes. Add the powdered sugar, lemon zest,and lemon juice and mix on low speed until combined. Increase the speed to medium and mix until creamy, 1-2 minutes. Add the heavy cream and whip the frosting until very light and fluffy, 2-3 minutes.
- When the cake has cooled completely, place one round on a platter or plate and spread the top evenly with frosting. Place the other cake round upside down on the frosting and press just lightly. Continue frosting with a thin spatula or offset spatula until the top and sides of the cake are evenly frosted. Garnish with blueberries and lemon slices, if desired.
- This cake, once frosted, lasts very well in the refrigerator for several days. Take it out an hour or two before serving or serve chilled, your choice!
