Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour, sifted
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 ¾ cups (350g) granulated sugar
  • ¾ cup (170g) unsalted butter, softened
  • 4 large eggs, room temperature
  • 1 cup (240ml) whole milk
  • 2 tsp pure vanilla extract
  • ½ cup (120ml) strawberry puree, fresh or thawed frozen
  • ¼ cup (25g) unsweetened cocoa powder
  • 1 ½ cups (340g) unsalted butter, softened (for frosting)
  • 6 cups (720g) powdered sugar, sifted
  • 4–6 tbsp (60-90ml) heavy cream
  • 2 tsp pure vanilla extract (for frosting)
  • ½ cup (120ml) strawberry jam or puree (for frosting)
  • ¼ cup (25g) unsweetened cocoa powder (for frosting)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch sheet pan with butter or non-stick spray and lightly dust with flour.
  2. In a large bowl, sift together flour, baking powder, salt, and cocoa powder. Set aside.
  3. Using a mixer, beat ¾ cup softened unsalted butter with granulated sugar until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, mixing well after each addition. Stir in vanilla extract.
  5. Divide batter: scoop one-third into a separate bowl and fold in strawberry puree. To the remaining two-thirds, fold in sifted dry ingredients alternately with milk. Mix just until combined.
  6. Pour chocolate batter evenly into prepared pan. Spoon strawberry batter in dollops on top and swirl lightly with a knife or skewer to create a marbled effect.
  7. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean. Cake should spring back lightly when touched.
  8. Cool in pan on wire rack for 20 minutes, then invert onto rack to cool completely.
  9. Prepare frostings: beat 1 ½ cups softened butter until creamy. Gradually add powdered sugar, alternating with heavy cream to desired consistency.
  10. Divide frosting into three bowls. Stir vanilla extract into one, fold strawberry jam or puree into second, and mix cocoa powder into third.
  11. Using an offset spatula, spread frostings in horizontal bands across the cake: strawberry on one side, vanilla in middle, chocolate on other. Gently blend where they meet for a soft swirl effect.
  12. Refrigerate cake for at least 30 minutes to set frosting before slicing.

Notes

Use softened butter for better creaming and aeration. Do not overmix batter after adding flour to avoid toughness. Chill cake before slicing to keep frosting layers clean. For stronger strawberry flavor, add a teaspoon of lemon juice to strawberry puree. Substitute Greek yogurt for milk to add moisture and tang. For dairy-free, use vegan margarine and plant-based milk. Gluten-free version can be made with gluten-free flour blend and xanthan gum.
