Ingredients & Little Kitchen Secrets
Here’s what I use for my favorite Strawberry Filling for Sheet Cake:
- 2 cups fresh or frozen strawberries, hulled and chopped
- ¾ cup granulated sugar
- 1 tablespoon cornstarch
- 2 teaspoons lemon juice
- ½ teaspoon vanilla extract (optional but magical!)
Little Kitchen Secrets:
- If your strawberries are frozen, let them thaw slightly, then drain excess liquid this keeps the filling thick and not watery.
- For a smoother filling, mash the strawberries gently with a fork or potato masher.
- Add a teaspoon of lemon zest for a fragrant, zesty twist.
How I Make It, Step by Step
- Place chopped strawberries in a medium saucepan over medium heat.
- Sprinkle sugar and cornstarch over the berries, stirring to coat evenly.
- Cook the mixture, stirring constantly, until the strawberries release their juices and the mixture thickens (about 6–8 minutes).
- Remove from heat and stir in lemon juice and vanilla extract.
- Let the filling cool completely before using it in your sheet cake.
Pro Tip: If you want a jammy texture, mash the berries slightly while cooking. If you prefer chunks, stir gently and avoid over-mashing.
How I Serve It at Home
I love spreading this Strawberry Filling for Sheet Cake between two or three layers of moist vanilla or chocolate sheet cake. A thin layer of buttercream or whipped cream on each side locks in the moisture and enhances the flavor. Sometimes, I even dollop a little extra on top before slicing it looks gorgeous and tastes heavenly!
For casual family treats, I use it as a topping for pound cake or even spread it over a simple sponge cake with a dusting of powdered sugar. The kids love it on cupcakes too a hidden strawberry surprise in every bite!
