Divide and Flavor Batter – Split batter evenly into 3 bowls. – Chocolate Layer: Mix cocoa powder into one portion. – Vanilla Layer: Add vanilla extract to the second portion. – Strawberry Layer: Add strawberry puree and pink coloring to the third portion. 4. Bake the Layers – Pour each batter into a separate prepared pan. Bake 20–25 minutes or until a toothpick comes out clean. 5. Cool and Assemble – Cool layers completely. Level tops if necessary. Stack layers in your chosen order, spreading frosting between each. Frost the outside and decorate as desired. 6. Serve and Store – Serve at room temperature.
