Ingredients
This easy strawberry cake filling is a thick and delicious strawberry filling, perfect for filling cakes, cupcakes, and macarons!
For the Strawberry 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 extract (optional)
- Pinch salt (optional)
How to Make Strawberry Cake Filling
Step 1: Whisk Ingredients Together
Start by whisking together water and cornstarch in a medium saucepan until fully mixed with no lumps remaining.
Step 2: Add Remaining Ingredients
Add in the sliced strawberries, sugar, lemon juice (if using), vanilla extract (if using), and salt to the saucepan.
Step 3: Bring to a Boil
Cook over medium to medium-high heat while stirring gently until the mixture comes to a boil.
Step 4: Boil Briefly
Let it boil for 30-60 seconds. Be careful not to overboil; otherwise, the cornstarch may lose its thickening power. You’ll notice it changing from an opaque milky pink color to a deeper red that’s more transparent.
Step 5: Simmer Until Thickened
Once it turns red, immediately reduce the heat to medium-low and let it simmer for about 8-10 minutes. The mixture should thicken enough to coat a spatula without dripping off. Remember, it will thicken further as it cools.

Common Mistakes to Avoid
When making your strawberry cake filling, it’s easy to run into a few common pitfalls. Here are some mistakes to watch for:
- Overcooking the mixture: It’s crucial not to boil the filling for too long. Boiling for more than a minute can cause the cornstarch to lose its thickening ability, resulting in a runny filling.
- Not mixing cornstarch properly: Ensure the cornstarch is thoroughly whisked with the water before adding other ingredients. Lumps can form if not mixed well, leading to an uneven texture.
- Using unripe strawberries: Fresh strawberries should be ripe and sweet. Unripe berries can make your filling tart and less enjoyable. Choose berries that are bright red with no green spots.
- Skipping the cooling step: Allow the filling to cool completely before using it in cakes or desserts. This helps it thicken further and ensures it holds its shape when layered.
- Neglecting to taste: Always taste your filling before using it. You might want to adjust the sugar or add more lemon juice based on your personal preference.
