Strawberry Cake Filling (Printable)
Quick strawberry filling of fresh berries, sugar and cornstarch—cools to set for cake layers, 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)
# How To Make It:
01 - In a medium saucepan, combine the diced strawberries, granulated sugar, and lemon juice. Stir to evenly coat the fruit.
02 - Place the saucepan over medium heat. Cook, stirring occasionally, for 5 to 7 minutes until the strawberries begin to release their juices and soften.
03 - In a small mixing bowl, whisk together cornstarch and water until smooth.
04 - Pour the cornstarch mixture into the saucepan. Stir constantly and continue cooking for an additional 3 to 5 minutes, or until the filling thickens and turns glossy.
05 - Remove from heat and stir in vanilla extract, if using. Let the filling cool completely; it will thicken further as it cools.
06 - Transfer any leftover filling to an airtight container and refrigerate for up to five days.
# Expert Tips:
01 -
- Your kitchen will smell like a strawberry patch in June — no candles required.
- It brings a fresh, homemade feel to store-bought cake layers or transforms simple cupcakes into something special.
02 -
- If you don’t whisk the cornstarch with water first, it will clump and you’ll have starchy bits in every bite — trust me, I learned the hard way.
- A pinch of extra lemon juice can save the filling if your strawberries are overly sweet and lacking brightness.
03 -
- The thinner you dice your berries, the faster the filling thickens and the truer the flavor.
- A scrape of lemon zest or a drop of almond extract can completely change its personality — experiment a little!
