Ingredients

Scale

Cake Batter

  • 1 package white cake mix
  • Water, as specified on the cake mix packaging
  • Vegetable oil, as specified on the cake mix packaging
  • Whole eggs, as specified on the cake mix packaging
  • 2 tablespoons unsweetened cocoa powder
  • 2 tablespoons seedless strawberry jam
  • 1/4 teaspoon red gel food coloring

Frosting

  • 1 cup softened butter
  • 2 1/4 cups icing sugar (powdered sugar)
  • 2 to 3 tablespoons milk
  • 1 teaspoon vanilla essence
  • 1 teaspoon seedless strawberry jam
  • Red gel food coloring as needed
  • 1 teaspoon unsweetened cocoa powder

Instructions

  1. Prepare the Cake Batter: Preheat your oven to 350°F (175°C). Spray the bottom of a 13×9-inch pan with cooking spray. In a large bowl, beat together the cake mix, water, vegetable oil, and eggs using an electric mixer on medium speed for about 2 minutes, scraping the sides occasionally to fully combine.
  2. Create Swirled Batter Colors: Divide the prepared batter into three portions. Place 1 1/4 cups batter in a small bowl and mix with 2 tablespoons cocoa powder for chocolate batter. In another small bowl, place 1 1/4 cups batter, add 2 tablespoons strawberry jam and 1/4 teaspoon red gel food coloring; stir until evenly colored. The remaining batter will stay plain vanilla.
  3. Layer and Swirl the Batter: Pour the plain batter into the prepared pan. Drop spoonfuls of the chocolate and strawberry batters randomly over the top. Use a table knife to gently swirl through the batters, creating a marbled pattern.
  4. Bake and Cool the Cake: Bake for 28 to 30 minutes or until a toothpick inserted in the center comes out clean. Remove from oven and let cool completely (about 1 hour) to prevent frosting melting.
  5. Make the Frosting: Beat softened butter in a large bowl on medium-high speed until creamy. Gradually add powdered sugar and continue beating until smooth. Add 2 tablespoons milk and vanilla essence; beat until well combined. If frosting is too thick, add additional milk 1 teaspoon at a time until spreadable.
  6. Color and Apply the Frosting: Set aside 1/4 cup vanilla frosting, mix in 1 teaspoon strawberry jam and red gel food coloring to desired shade. In another small bowl, combine 3 tablespoons vanilla frosting with 1 teaspoon cocoa powder for chocolate frosting. Spread remaining vanilla frosting evenly over cooled cake. Drop spoonfuls of strawberry and chocolate frosting on top, then use a spatula to swirl for a decorative finish.
  7. Serve and Store the Cake: Serve immediately once frosted. Store leftovers loosely covered at room temperature to maintain freshness.

Notes

  • Ensure the cake is completely cool before frosting to avoid melting the frosting.
  • Use seedless strawberry jam for a smooth texture in batter and frosting.
  • Adjust food coloring gradually to achieve your preferred intensity.
  • This recipe can be made using boxed white cake mix for convenience.
  • Leftover cake is best consumed within 2-3 days when stored properly at room temperature.
