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
- â…” cup sugar (more or less to taste)
- 2 tbs lemon juice (optional)
- 1 tsp vanilla extract (optional)
- Pinch salt (optional)
How to Make Strawberry Cake Filling
Step 1: Whisk Together Ingredients
Start by whisking together the water and cornstarch in a medium saucepan until fully mixed. Ensure there are no lumps.
Step 2: Add Remaining Ingredients
Add in the sliced strawberries, sugar, lemon juice, vanilla extract, and salt into the saucepan.
Step 3: Cook Mixture
Cook over medium to medium-high heat until the mixture begins to boil.
Step 4: Boil Briefly
Let it boil for about 30-60 seconds—no more than one minute. Be cautious not to overboil; this can affect the thickening ability of the cornstarch. The color should transition from an opaque milky pink to a deeper red that is more transparent.
Step 5: Simmer Until Thickened
Once it turns red, reduce the heat to medium-low. Let it simmer for about 8-10 minutes. It should thicken enough to coat a spatula without dripping off. Remember that it will thicken more as it cools.
Step 6: Cool Before Using
Remove from heat and allow the filling to cool completely before using it in your favorite dessert creations.

How to Perfect Strawberry Cake Filling

Adjust sweetness: Taste your mixture before cooking and adjust sugar levels according to your preference. Fresh strawberries may require less sugar than frozen ones.
-
Don’t overboil: Boil just enough to thicken; overcooking can lead to loss of consistency. Keep an eye on the color change as an indicator.

Common Mistakes to Avoid
Making strawberry cake filling can be simple, but there are common errors to watch out for.
-
Not measuring ingredients accurately: Ensure you measure both the sugar and cornstarch precisely. Too much or too little can affect the thickness of your filling.
-
Overcooking the mixture: Boil the filling only for 30-60 seconds. Overboiling can weaken the thickening properties of cornstarch, resulting in a runny filling.
-
Skipping the cooling step: Allow your strawberry cake filling to cool completely before using it in desserts. This helps it thicken further and improves its texture.
-
Ignoring fruit quality: Use fresh or good-quality frozen strawberries. Poor-quality fruit can lead to a less flavorful and vibrant filling.
-
Not adjusting sweetness: Taste your filling after cooking. Depending on your preference and the ripeness of your strawberries, you may want to add more or less sugar.
