Strawberry Cake Filling (Printable)
Fresh strawberry filling thickened with cornstarch — glossy and spreadable, ideal for layering or swirls.
# What's Needed:
→ 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, combine diced strawberries, granulated sugar, and lemon juice. Stir to evenly coat the berries.
02 - Set the saucepan over medium heat. Cook for 5 to 7 minutes, stirring occasionally, until the strawberries begin to soften and release juices.
03 - In a small bowl, whisk together cornstarch and water until completely smooth.
04 - Pour the cornstarch slurry into the saucepan while stirring constantly. Continue cooking for 3 to 5 minutes until the mixture thickens and turns glossy.
05 - Remove the saucepan from heat. Stir in vanilla extract, if using.
06 - Allow the filling to cool completely before layering into cakes or pastries. The mixture will thicken further as it cools.
07 - Transfer any leftover filling to an airtight container and refrigerate for up to five days.
# Tips for Success:
01 -
- You can sneak little spoonfuls of this filling while the cake cools and no one will ever know.
- I keep coming back to it because it tastes pure and bright, letting the strawberries really shine.
02 -
- If you rush and don’t let the filling cool, it’ll run out the sides of your cake just when you want those layers clean.
- Stir constantly once you add the cornstarch or else bits may set before they blend—that’s how I learned to never step away.
03 -
- If you’re impatient, place the pan in an ice bath to cool the filling faster—just don’t get water inside.
- Adding vanilla right after cooking but before cooling locks in extra aroma you’ll notice in every bite.
