Strawberry cake filling (Print View)

Fresh strawberry filling thickened with cornstarch and brightened with lemon; cools to a glossy spread for layers or cupcakes.

# What You 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)

# How to Make It:

01 - In a medium saucepan, mix the diced strawberries, granulated sugar, and lemon juice. Stir evenly to coat the fruit.
02 - Place the saucepan over medium heat. Cook, stirring occasionally, for 5 to 7 minutes until strawberries release juices and soften.
03 - In a small bowl, whisk cornstarch and water together until fully dissolved and smooth.
04 - Add cornstarch slurry to the saucepan. Stir constantly and cook for another 3 to 5 minutes until the mixture thickens and develops a glossy texture.
05 - Remove the saucepan from heat. Stir in pure vanilla extract if using. Allow the filling to cool completely before use; it will continue to thicken as it cools.
06 - Transfer cooled filling to an airtight container and refrigerate for up to five days.

# Expert Tips:

01 -
  • A spoonful makes even the simplest cake taste bakery-special and you’ll know it’s homemade.
  • It’s the ultimate multitasker: equally at home layered in cakes, tucked into cupcakes, or swirled onto breakfast yogurt.
02 -
  • Adding cornstarch too soon or without whisking makes the sauce lumpy—always mix it with water first.
  • Allow the filling to cool before using, or warm filling will soak right through your cake layers.
03 -
  • Don’t walk away while adding the cornstarch mixture—the bottom can scorch fast.
  • A splash more lemon at the end can save the filling if your berries are super-sweet.
