Description

This refined Blackberry Lemon Cake balances sharp, zesty citrus with jammy fruit through a careful emulsion of high-quality fats. Perfect for bakers seeking precision, this cake features a tender crumb and a stable cream cheese frosting that beautifully showcases fresh, seasonal berries.


Ingredients

  • 2 cups unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs, room temperature
  • 1 cup sour cream
  • 1/2 cup fresh lemon juice
  • 2 tablespoons lemon zest
  • 3 cups all-purpose flour
  • 1 tablespoon baking powder
  • 1/2 teaspoon baking soda
  • 1 teaspoon sea salt
  • 16 ounces cream cheese, softened
  • 1 cup heavy whipping cream
  • 1/2 cup seedless blackberry preserves
  • 2 cups fresh blackberries
  • 1 teaspoon vanilla extract


Instructions

  1. Preheat and prep. Preheat oven to 350°F and line three 8-inch cake pans with parchment paper.
  2. Infuse citrus sugar. Rub lemon zest into granulated sugar with fingertips until fragrant and damp.
  3. Whisk liquid base. Emulsify butter, lemon juice, sour cream, eggs, and vanilla into the sugar until uniform.
  4. Incorporate dry ingredients. Sift flour, baking powder, baking soda, and salt, then fold into the wet mixture until just combined.
  5. Divide and smooth. Distribute batter evenly into prepared pans and smooth surfaces with an offset spatula.
  6. Bake the layers. Bake for 22 to 24 minutes until golden and set, then cool on a wire rack.
  7. Prepare cream base. Beat cream cheese with sugar, zest, and salt until silky and glossy.
  8. Aerate the cream. Slowly whip in chilled heavy cream until the frosting reaches stiff, stable peaks.
  9. Fold in preserves. Gently swirl blackberry preserves into the frosting to create an elegant marbled effect.
  10. Assemble and finish. Layer cakes with frosting and fresh berries, finishing with a final decorative coating.

Notes

  • Ensure all dairy ingredients are at room temperature to prevent the batter from curdling during emulsification.
  • Rubbing zest into sugar is a vital step that releases essential oils for a more potent lemon flavor.
  • Avoid overmixing the batter once the flour is added to ensure a soft and tender cake crumb.
  • Use a serrated knife dipped in hot water to achieve clean, professional slices without tearing the layers.
  • Keep heavy cream well-chilled to ensure the frosting achieves a stable, stiff peak that holds up under fruit.
