Strawberry Cake Filling (Printable Version)
Fresh strawberry filling thickened with cornstarch and lemon; glossy, spreadable, ready for layers or swirls.
# Ingredient List:
→ 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)
# Step-by-Step Instructions:
01 - Place diced strawberries, granulated sugar, and lemon juice in a medium saucepan. Stir well to evenly coat the strawberries.
02 - Set saucepan over medium heat. Cook, stirring occasionally, for 5 to 7 minutes until strawberries soften and release their juices.
03 - In a small mixing bowl, whisk cornstarch and water together until the mixture is smooth and lump-free.
04 - Pour cornstarch mixture into the saucepan. Stir constantly and cook for an additional 3 to 5 minutes until the filling thickens and turns glossy.
05 - Remove saucepan from heat. Stir in vanilla extract, if desired.
06 - Allow the filling to cool completely before using. The texture will continue to thicken as it cools. Transfer to an airtight container and refrigerate if not using immediately.
# Tips from hearthlykitchen:
01 -
- Youll know exactly whats inside your cake—just pure, fresh strawberries, no mystery ingredients.
- It gently sets as it cools, making those cake slices picture-perfect every time.
02 -
- I once tried to rush the thickening and ended up with runny filling slipping through my cake layers—patience is key.
- Testing the thickness by dragging a spatula across the bottom of the pan taught me the perfect moment to remove it from the heat.
03 -
- Stir constantly during thickening—walking away is when sticking happens.
- A drop of vanilla at the end gives bakery-style depth that no one can guess.
