Ingredients Needed

Strawberry Cake Filling ingredients in small bowls
  • Strawberries: You can use fresh or frozen strawberries.
  • Lemon Juice: I recommend using fresh lemon juice, but in a pinch, you can use store-bought lemon juice.
  • Cornstarch: Don’t have cornstarch? Swap it out for tapioca starch! This will help thicken the strawberry filling.

Step by Step Instructions

Step 1: Whisk together the cornstarch and water in a small bowl. Set aside.

Step 2: Add the chopped strawberries, lemon juice, and sugar to a medium saucepan and place over medium-low heat.

Step 3: Stir the mixture on the stove until it simmers. Reduce the heat to low and cook until it has reduced, around 8-10 minutes.

Step 4: Add the cornstarch slurry and stir to combine. The mixture should continue to thicken. Remove from the heat when the mixture coats the back of a spoon.

Step 5: Set aside and let it cool completely (it’ll continue to thicken!)

Step 6: Once cooled, transfer to an airtight container and chill for at least 1 hour.

Expert Tips

  • This recipe makes 1 cup of cake filling, so you may need to double the recipe depending on what you’re using it for! 
  • Make sure you let the cake filling cool completely, and then place it in the refrigerator for at least an hour before using it. That way, the mixture has enough time to properly thicken.
  • Don’t skip out on the cornstarch! It helps thicken up the mixture.
  • The lemon juice helps brighten up the strawberry flavor, so don’t miss that out either.

Storage Instructions

Place in an airtight container in the fridge for up to 5-7 days. You can also freeze it for up to 2 months.
