This layered cake features soft lemon cake filled and topped with lightly sweetened mascarpone whipped cream and fresh blueberries. Sometimes dusted with powdered sugar or finished with lemon zest, it’s a refreshing and crowd-pleasing dessert.
For the lemon cake layers:
2½ cups all-purpose flour
2½ teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
1 cup unsalted butter, room temperature
1½ cups granulated sugar
4 large eggs
1 tablespoon lemon zest
¼ cup fresh lemon juice
1 teaspoon pure vanilla extract
1 cup buttermilk
For the mascarpone cream filling:
8 oz mascarpone cheese
1½ cups heavy cream
¼ cup powdered sugar
1 teaspoon vanilla extract
For the topping/filling:
2 cups fresh blueberries (plus more for garnish)
Lemon zest for garnish
Optional: powdered sugar for dusting
Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line the bottoms with parchment paper.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In a large bowl, beat the butter and sugar on medium-high speed for 3–4 minutes, until light and fluffy.
Beat in the eggs one at a time, then add the lemon zest, lemon juice, and vanilla extract.
With the mixer on low, add the dry ingredients in three additions, alternating with the buttermilk. Begin and end with the dry ingredients. Mix until just combined—don’t overbeat.
Divide the batter evenly between the prepared pans. Bake for 25–30 minutes, or until a toothpick comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
In a chilled mixing bowl, whip the mascarpone, heavy cream, powdered sugar, and vanilla extract together until soft peaks form. Be careful not to overmix.
Place one cake layer on a serving plate. Spread half the mascarpone cream over the top, and scatter with half the blueberries. Add the second cake layer, and repeat with the remaining cream and berries.
Sprinkle lemon zest over the top and dust lightly with powdered sugar, if desired. Chill for 30–60 minutes before serving for easier slicing.
