How to Make the Perfect Vanilla-Chocolate-Strawberry Sheet Cake

This colorful cake comes together from one batter, divided into three flavorful sections—each with its own personality.

STEP-BY-STEP INSTRUCTIONS:

1. Preheat and prepare:
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch sheet pan or line with parchment paper for easy removal.

2. Make the base batter:
In a large bowl, whisk together the flour, baking powder, baking soda, and salt. In a separate bowl, beat together the sugars, oil, eggs, and vanilla until smooth. Alternate adding the dry ingredients and buttermilk to the wet mixture, mixing just until combined. Don’t overmix.

3. Divide the batter:
Split the batter evenly into three bowls (about 1½ cups each).

• Vanilla section: Leave one portion as-is.
• Chocolate section: Stir cocoa powder into one portion until fully combined.
• Strawberry section: Stir in strawberry powder or gelatin. Add pink food coloring, if using, to brighten the color.

4. Assemble in the pan:
Spoon each flavor of batter into the prepared pan in three long, side-by-side sections (lengthwise or widthwise, your choice). Use a spatula to gently nudge the batters next to each other. Try not to overlap too much so the colors stay distinct.

5. Bake:
Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Let cool completely before frosting or serving.

6. Frost (optional):
Make the strawberry frosting by beating butter until smooth. Add powdered sugar, strawberry puree, vanilla, and salt. Mix until fluffy, adding a splash of milk if needed for spreadability. Frost the cooled cake and decorate with sprinkles, strawberries, or chocolate shavings if desired.

HELPFUL TIPS:

• Use freeze-dried strawberries: Blitz into powder for a natural flavor without added moisture.
• Don’t swirl the batter: You want three distinct stripes of flavor.
• Let it cool fully: The cake sets as it cools and becomes easier to slice cleanly.
• Add fresh fruit: Top with sliced strawberries for an extra pop of flavor and color.
