Why a Strawberry Sheet Cake Works Best for Parties

Sheet cakes serve a crowd with minimal fuss. They cut into neat squares. They travel well. They also look festive when topped with fresh berries.

  • Quick to slice and plate for many guests.
  • Easy to dress up with a simple garnish of sliced strawberries.
  • A great canvas for seasonal flavors and bright colors.

Ingredients: Fresh strawberry cake and cream cheese frosting

Below are the ingredients for one 13 x 9-inch sheet cake and its frosting. Use ripe strawberries for the best flavor.

Cake components

  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 tablespoon fresh lemon juice
  • 2 1/4 cups all-purpose flour
  • 1/4 cup cornstarch
  • 1/2 teaspoon baking soda
  • Pinch of salt
  • 2 tablespoons strawberry-flavored gelatin (Jell-O)
  • 1 cup whole milk
  • 3/4 cup diced fresh strawberries
  • Optional: a few drops of pink or red food coloring

Frosting components

  • 8 oz cream cheese, softened
  • 1 1/2 cups powdered sugar, divided
  • 1 teaspoon vanilla extract
  • 2/3 cup diced fresh strawberries
  • 1 1/2 cups heavy cream
  • 3 tablespoons fresh lemon juice
  • Optional: pink or red food coloring

Baking the cake: a clear step-by-step guide

Follow these steps to make a moist strawberry sheet cake with bright berry flavor.

  1. Preheat oven to 350°F (175°C). Line a 13 x 9-inch pan with parchment, leaving an overhang. Spray parchment with cooking spray.
  2. In a bowl, whisk together flour, cornstarch, baking soda, salt, and strawberry gelatin. Set aside.
  3. Cream the softened butter at medium speed until smooth. Add sugar and beat until light and fluffy.
  4. Add eggs one at a time, beating after each. Mix in vanilla and lemon juice.
  5. Add half the dry mix, then the milk, then the remaining dry mix. Stir until combined.
  6. Fold in diced strawberries. Add a few drops of food coloring if you want a more vivid pink hue.
  7. Pour batter into prepared pan and smooth the top. Bake 30–40 minutes, until a toothpick comes out clean.
  8. If the top browns too quickly, tent with foil. Cool in the pan 30 minutes, then transfer to a rack to cool completely.

Making the strawberry cream cheese frosting

This frosting is light, slightly tangy, and studded with fresh berries. It spreads easily over a cooled sheet cake.

  1. In a chilled bowl, beat heavy cream with lemon juice until soft peaks form. Gradually add 1/2 cup powdered sugar and whip to stiff peaks. Set aside.
  2. In another bowl, beat the cream cheese with the remaining 1 cup powdered sugar and vanilla until very smooth.
  3. Gently mix the diced strawberries into the cream cheese. Add food coloring if desired.
  4. Fold half of the whipped cream into the cream cheese mixture to lighten it. Fold in the remaining whipped cream until uniform.
  5. Spread the frosting over the fully cooled cake. Chill slightly to set if you prefer firmer slices.
  6. Top with extra strawberry slices just before serving for a fresh look.

Timing, serving tips, and storage advice

  • Prep time: about 25 minutes. Bake time: 35 minutes. Total time: roughly 1 hour.
  • Serve chilled or at room temperature. Chilling helps the frosting firm up for cleaner slices.
  • Store leftovers covered in the refrigerator for up to 3 days.
  • For travel, keep cake chilled in a cooler and add fresh fruit at the destination.
  • Garnish ideas: whole strawberries, thin slices, or a light dusting of powdered sugar.

Variations and recipe ideas to try next

  • Make a layered strawberry shortcake using this batter for the layers.
  • Swap the strawberry gelatin for raspberry for a different tart note.
  • Try a no-bake strawberry jello lasagna for a no-oven alternative.
  • Combine chocolate and strawberries for a richer twist on the classic.
