Homemade blueberry filling is great for cakes and cupcakes. With only 5 ingredients, this recipe comes together in less than 10 minutes! This filling is incredibly versatile and tastes so much better than store-bought filling!
Ingredients for Blueberry Filling
- Frozen blueberries: I love using frozen blueberries to make this recipe. The blueberries are flash frozen at the peak of freshness, so you will get great blueberry flavor year round. I don’t recommend using fresh blueberries as there may not be enough liquid for the filling.
- Granulated sugar: For sweetness.
- Lemon juice: Brightens the flavor of the blueberries. Fresh is best.
- Cornstarch + water: Creates a slurry that thickens the filling.
How to Make Blueberry Filling
- In a saucepan, combine frozen blueberries, granulated sugar, and lemon juice over medium-low heat on the stove.
- Simmer until the blueberries have softened and the mixture begins to bubble. Stir occasionally to prevent burning.
- In a small bowl, mix together cornstarch and water.
- Add the cornstarch slurry to the blueberry mixture and immediately stir to combine. Remove from the heat once the liquids have thickened.
- Allow the filling to cool to room temperature before transferring to a bowl and chilling in the fridge for at least one hour before use.

Can this be made with sugar free subsitute? Looks delicious, blueberries are one of my favorite.
I haven’t tested that personally, but I don’t see why that wouldn’t work! Let me know if you give it a try!
