Strawberry Cake Filling Recipe
Introduction
This strawberry cake filling is perfect for adding a fresh, fruity burst to your desserts. Made with simple ingredients and cooked to a luscious, thick consistency, it works beautifully in cakes, cupcakes, and pastries. You’ll love its natural sweetness balanced with a hint of lemon.

Ingredients
- 3 cups strawberries (sliced in half)
- 1/4 cup granulated sugar
- 1 tbsp lemon juice
- 1 tsp cornstarch (mixed with a little bit of water)
- 1 tsp lemon zest (optional)
Instructions
- Step 1: Wash, hull, and chop the fresh strawberries. For a chunkier filling, leave the pieces slightly larger. You can also use frozen strawberries if fresh are unavailable.
- Step 2: Place the strawberries in a saucepan along with sugar, lemon juice, and lemon zest. Heat over medium heat until the mixture starts to bubble and the strawberries release their juices.
- Step 3: Reduce the heat to medium-low and let it simmer for 20 minutes, stirring occasionally to prevent sticking.
- Step 4: In a small bowl, mix the cornstarch with a little water to form a smooth slurry. Gradually add this to the strawberry mixture while stirring constantly to avoid lumps.
- Step 5: Continue cooking the filling over medium-low heat, stirring frequently, until it thickens and coats the back of a spoon, which usually takes a few minutes.
- Step 6: Remove the filling from heat and allow it to cool completely. It will thicken further as it cools. Use immediately in your favorite desserts or store in the refrigerator.
Tips & Variations
- For extra flavor, add a splash of vanilla extract once the filling is off the heat.
- Use frozen strawberries if fresh are out of season, but reduce simmering time slightly.
- If you prefer a smoother filling, mash the strawberries gently after cooking before adding the cornstarch slurry.
Storage
Store the cooled strawberry filling in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently on the stove or in the microwave, stirring occasionally to restore the smooth texture.
