Strawberry Cake Filling (Printable)

Fresh strawberry filling thickened with cornstarch and sugar, glossy and perfect for cake layers or cupcakes.

# 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 - Place strawberries, granulated sugar, and lemon juice in a medium saucepan. Stir to evenly coat the fruit.
02 - Set saucepan over medium heat; cook for 5 to 7 minutes, stirring occasionally, until strawberries release juices and begin to soften.
03 - Whisk cornstarch and water together in a small bowl until smooth.
04 - Pour the cornstarch mixture into the saucepan. Stir constantly and cook for an additional 3 to 5 minutes, until the filling thickens and achieves a glossy appearance.
05 - Remove from heat and incorporate vanilla extract, if desired.
06 - Allow filling to cool completely before using. It will continue to thicken as it cools. Transfer any leftovers to an airtight container and refrigerate for up to five days.

# Helpful Tips:

01 -
  • It’s a foolproof shortcut to making any average cake taste bakery-special with almost no effort.
  • Strawberry filling is endlessly versatile and doubles up for breakfast, dessert, or a sneaky midnight snack.
02 -
  • If you rush the cooking, the filling won’t thicken properly and might run right out of your cake layers.
  • Adding the cornstarch too quickly creates lumps—slow and steady makes all the difference.
03 -
  • Stir the filling constantly after adding the cornstarch for the smoothest result.
  • Sneak in a touch of vanilla or even almond extract for a subtle twist that feels gourmet.
