Strawberry Cake Filling (Printable)
Bright strawberry filling thickened with cornstarch and lemon, perfect for layering cakes, cupcakes, or yogurt.
# What You’ll Need:
→ Fruit
01 - 2 cups fresh strawberries, hulled and diced
→ Sweeteners & Thickeners
02 - 1/3 cup granulated sugar
03 - 1 tablespoon lemon juice
04 - 2 tablespoons cornstarch
05 - 1/4 cup water
→ Flavorings
06 - 1/2 teaspoon pure vanilla extract (optional)
# Directions:
01 - In a medium saucepan, combine the diced strawberries, granulated sugar, and lemon juice. Stir to coat strawberries evenly.
02 - Place the saucepan over medium heat and cook for 5 to 7 minutes, stirring occasionally, until strawberries release juices and begin to soften.
03 - In a small mixing bowl, whisk together the cornstarch and water until smooth with no visible lumps.
04 - Pour the cornstarch mixture into the saucepan. Stir constantly and cook for an additional 3 to 5 minutes, or until the mixture thickens and develops a glossy appearance.
05 - Remove the saucepan from heat. Stir in the vanilla extract, if desired.
06 - Allow the filling to cool completely before using. Refrigerate in an airtight container for up to 5 days; the filling will continue to thicken as it chills.
# Expert Advice:
01 -
- You can make it ahead, stash it in the fridge, and surprise yourself with filling for anything.
- The way fresh strawberries brighten up a plain cake feels like a little party trick.
02 -
- Once I skipped whisking the cornstarch fully, and regretted the lumps—now I always make it super smooth first.
- Letting the filling cool completely is crucial, otherwise it will run right out of your cake layers.
03 -
- Never skip the cooling time—warm filling makes cakes soggy and hard to layer.
- A tiny pinch of salt, added with the sugar, can deepen the strawberry flavor more than you’d expect.
