Ingredients
This easy strawberry cake filling is a thick and delicious strawberry filling, perfect for filling cakes, cupcakes, and macarons!
For the Filling
- 16 oz (2 ½ to 3 cups) fresh or frozen strawberries, sliced
- ¾ cup water
- 3 tbs cornstarch
- ⅔ cup sugar (more or less to taste)
- 2 tbs lemon juice (optional)
- 1 tsp vanilla (optional)
- Pinch salt (optional)

How to Make Strawberry Cake Filling
Step 1: Mix Water and Cornstarch
Whisk together water and cornstarch in a medium saucepan until it is fully mixed and there are no lumps.
Step 2: Add Remaining Ingredients
Add in the sliced strawberries, sugar, lemon juice (if using), vanilla (if using), and salt (if using).
Step 3: Cook Over Medium Heat
Cook over medium to medium-high heat until the mixture begins to boil.
Step 4: Boil Briefly
Let boil for 30-60 seconds—no more than a minute. Avoid overboiling as it may compromise the cornstarch’s thickening ability. The color should change from opaque milky pink to deeper red.
Step 5: Simmer Until Thickened
Once it turns red, immediately reduce heat to medium-low. Let it simmer for about 8-10 minutes. The mixture should thicken enough to coat a spatula without dripping off. Remember that it will thicken more as it cools.
Step 6: Cool Completely Before Use
Remove from heat and allow the filling to cool completely before using it in your favorite dessert creations.

- Not adjusting sweetness: Everyone’s taste buds are different. Always taste your filling before cooling and adjust sugar as needed to achieve your desired sweetness.
- Skipping lemon juice: The acidity from lemon juice enhances flavor and balances sweetness. Don’t skip this step unless you have a specific reason.
