Ingredients

Scale

Cake

  • 1 1/2 cups granulated sugar
  • 2 tbsp fresh lemon zest
  • 1 1/2 cups + 2 tbsp cake flour
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon fine sea salt
  • 5 1/2 tablespoons unsalted butter, cubed, room temperature
  • 1/4 cup + 1 tablespoon canola oil
  • 1 whole egg, room temperature
  • 1/2 cup whole milk, room temperature
  • 1/2 cup sour cream, room temperature
  • 1 teaspoon vanilla extract

Mascarpone Frosting

  • 4 ounces mascarpone cheese, cold
  • 1/2 cup powdered sugar
  • 1/2 cup heavy whipping cream, cold
  • 1 teaspoon vanilla extract
  • 1 teaspoon lemon zest

Berry Topping

  • 1 cup fresh blackberries
  • 3/4 cup chopped fresh strawberries
  • 2/3 cup fresh raspberries
  • 1 tablespoon strawberry, blackberry, or raspberry jam

Instructions

  1. Prepare the Pan and Preheat Oven: Line an 8×8 baking pan with parchment paper to prevent sticking and set it aside. Preheat your oven to 350°F (180°C) to ensure it’s ready for the cake.
  2. Combine Dry Ingredients: In a stand mixer bowl, rub together the lemon zest and sugar with your fingers to release the oils and fragrance. Then add the cake flour, baking powder, and sea salt. Mix until well combined to evenly distribute the leavening agents and salt.
  3. Add Butter: Add the cubed unsalted butter to the dry mixture and mix on low speed until the mixture resembles coarse sand. This helps create a tender crumb.
  4. Incorporate Wet Ingredients: Mix in the canola oil, whole egg, whole milk, sour cream, and vanilla extract until just combined. Avoid overmixing to keep the cake tender and moist.
  5. Bake the Cake: Pour the batter into the prepared baking pan, spreading evenly. Bake for 23 to 26 minutes, or until a toothpick inserted in the center comes out clean. Then transfer to a wire rack and let the cake cool completely before frosting.
  6. Make the Mascarpone Frosting: In a mixing bowl, beat cold mascarpone cheese with powdered sugar until combined. Add cold heavy whipping cream, vanilla extract, and lemon zest. Whisk first on low speed to mix, then increase to medium speed and beat until stiff peaks form. Avoid overmixing to prevent the frosting from curdling.
  7. Prepare the Berry Mixture: In a medium bowl, gently combine the fresh chopped strawberries, blackberries, raspberries, and jam, folding carefully to keep the berries intact.
  8. Assemble the Cake: Spread the mascarpone frosting evenly over the cooled cake to the edges. Top with the berry mixture. For best presentation and to avoid juices soaking into the frosting, add the berries just before serving if not serving immediately.

Notes

  • When measuring cake flour, spoon it gently into the measuring cup and level off to avoid compacting, resulting in more accurate flour quantity.
  • Using room temperature ingredients ensures even mixing and better cake texture.
  • If you prefer a tangier frosting, you can add a teaspoon of lemon juice along with the zest.
  • To prevent the cake from sticking, make sure the parchment paper is properly fitted to the baking pan.
  • If you want to prepare the cake in advance, store the plain cake and frosting separately, and assemble just before serving to keep the berries fresh.
