Ultimate Strawberry Filling for Cakes
Strawberry filling is an ultimate ingredient that works excellently in countless dessert recipes. Including cake fillings, tart fillings, and fruit tarts. You can also use it as a topping for your favorite ice cream or breakfast pancakes. In addition, this recipe is so simple and easy that you will never want to use a store-bought strawberry filling again.
Many of my friends buy strawberry filling from the supermarket. Often, because they don’t know how easy it is to make it at home. It is super easy, and you can use fresh or frozen fruits to make it.
So, what do you do when you have extra strawberries in season? Well, I do a few things.
- First of all, I make a delicious strawberry filling and place the extra in a ziplock bag, so they use less space.
- And, I also love to freeze strawberries individually. As a result, I have frozen strawberries year-round for my desserts and smoothies.
- In addition, I also make a big batch of strawberry jam without pectin. And my recipe is low in sugar; therefore, you can eat more of it.
Why make a homemade strawberry filling?
- A fruit-filling recipe is so versatile. Of course, it is delicious on its own, but there is so much more you can do with fruit fillings apart from using it as a filling for cakes, pies, tarts, pastries, desserts, cheesecakes, etc. (more on that below)- try it over pancakes, waffles, French toast.
- Homemade fruit fillings are less sweet, fruitier, and unlike commercial fruit fillings, they are not loaded with sugar, flavorings, and additives
- The best part is that it takes just 5 to 7 minutes to make it. And, it has a shelf life of up to 4 days in the fridge. Leftovers can be kept in the fridge for months.
- The list of ingredients is just 4: fruit, lemon juice, sugar, cornstarch, and water.
Ingredients and substitutes
- Fresh Strawberries – While I’m using fresh strawberries in season, I have also used frozen ones.
- Sweetened or unsweetened frozen strawberries – And if you do use frozen strawberries, make sure to check if they are sweetened or unsweetened. Some frozen brands have sugar added as a preservative. You can still use them, and yet reduce the sugar as appropriate for the recipe.
- Cornstarch – I think this is by far the most commonly used and preferred ingredient. And yet, if you cannot use cornstarch, try arrowroot powder or potato starch. I have used both on two different occasions – and they are almost the same.
They both thicken the filling and work pretty much the same way. So, I would say use a tad less. And yet, since I used both only once so far, I’d say instead of adding all the slurry at once, save a little until the end and see if you need it. - Sugar – I prefer to use fine-grain sugar for this, so I don’t overcook the strawberries to a pulp.
- Lemon Juice – Really brings out the flavor so much more.
Step-by-step: Strawberry Cake Filling
- Prep – Wash, clean, and hull strawberries. Chop them into equal-sized pieces
Pro tip – Hull simply means to remove the stalk and core (core is the white stalk below the green leaves because it stays hard)
- Combine – Place strawberries in a saucepan with half the water, sugar, lemon juice, and salt. Place it on medium heat until all the sugar is dissolved, shaking the pan to cook evenly.
Pro tip – The sugar will melt, and the mixture will look very runny. But it will be ok as it cooks. - Simmer – Continue to cook a minute more, then use a vegetable or potato masher and mash the fruit.
Pro tip – Mashing the fruit is optional, but it will create a softer, smoother-textured filling - Slurry – Add cornstarch to the remaining water and stir well. Add it to the strawberries
Pro tip – Cornstarch tends to settle down, so make sure to stir before you add it to anything
- Thicken – Continue to cook on medium until it comes to a boil- the mixture will thicken and look glossy. The color will change from an opaque light red to a translucent deep red. When glossy and thick enough to coat the back of a wooden spoon or spatula, it’s ready.
Pro tip – It is important that the cornstarch comes to a boil; only then will it go from opaque to a transparent, glossy sheen. This means the cornstarch is cooked. - Optional – At this point, you can strain the filling by pouring it through a sieve. I like to leave it fruity and chunky just as I have here.
Pro tip – Straining will remove all the fruit fiber and give a smoother filling consistency, which may be ideal for some desserts - Store – Remove from heat. Pour into a mason jar. Let cool completely.
Consistency
- The cornstarch will continue to thicken as the filling cools. You can add a few tablespoons of hot water to adjust the consistency.
- For a cake filling, I like to make a thick consistency so it does not ooze out of the cake sides.
- For pies and tarts, I like a bit of syrup.
- And for desserts, I like to mash the fruit more so it is almost like a thick syrup consistency.
Tips for Success
- You can use fresh or frozen fruits. Make sure to check if the fruits are sweetened and adjust the sweetness accordingly.
- Also, if the fruits are frozen, you may need a little less water. You can omit the additional water and add only sugar, lemon juice, and salt. Once the sugar has dissolved, adjust the water as needed.
- Use fine-grain white sugar so it dissolves easily and does not affect the filling’s color. For example, brown sugar can give a very dull red color.
- Overcooking the fruit filling causes the cornstarch to become lumpy. If that happens, just add a little water and cook until it reaches the right consistency.
- This filling will stay in the fridge for a week, but can be frozen in the fridge for up to 3 months.
- This batch would be enough
- cake filling for 2 x 8-inch cake layers,
- a tart filling for one 9-inch tart and
- dessert servings with a 9-inch cheesecake.
- You can use this same recipe to make any other fruit filling, such as blueberry, blackberry, raspberry, mango, cherry, etc.
How to use strawberry fillings?
- Cake filling – You can use fruit filling instead of jam filling in cakes between layers of cake with a buttercream frosting dam and more fresh fruits. See how to fill and frost cakes. Fruit fillings are especially delicious with whipped cream or cream cheese frosting.
- Cake sides – I love to serve it on the side of my vanilla or chocolate pound or bundt cakes.
- Pie filling – Spread it on a prebaked shortcrust pastry shell with vanilla pastry cream as a base, and also top it with whipped cream.
- Spoon fruit fillings over pancakes or waffles for a delicious breakfast or brunch treat.
- Crepes – The strawberry filling makes a delicious filling for crepes. Simply spoon some filling onto a cooked crepe and fold it up.
- Tart filling – line a tart pan with rich shortcrust pastry, pour in the cooled strawberry filling, and top with a lattice crust. Bake until golden.
- Deserts – A fruit filling can take any dessert to the next level. Serve it with pound Cake.
- Pastry – bake it in puff pastry or Danish pastry dough over pastry cream or cream cheese filling, similar to this strawberry braided pastry, blackberry braided pastry, or Danish pastry rolls.
- Turnovers – Use cake filling for homemade turnovers. Simply spoon some filling onto a square of puff pastry, fold it over, and seal the edges.
- Cheesecake– Top it over your favorite New York cheesecake or mini strawberry or raspberry cheesecakes. Try this Crustless Strawberry Ricotta Cheesecake with Strawberry Sauce.
- Yogurt or oatmeal parfaits: Spoon strawberry filling over plain yogurt or oatmeal for a delicious and filling breakfast.

- You can use this same recipe to make any other fruit filling such as blueberry, blackberry, raspberry, mango, cherry, etc.
- Doubling the recipe – If you double the amount do not double the amount of water and cornstarch. You can add 1/2 cup water with 1 tbsp of cornstarch for up to 500 grams / 15 oz of fruit. Otherwise, it takes longer to reduce the water.
- The cornstarch needs to be activated for the filling to thicken up. Otherwise, it will be very syrupy with a starchy taste.
- If the filling is too thick means the water is reduced considerably, you can add a little more to bring it to consistency. Add regular water when still hot or warm water when the filling has cooled.
- When cooled, if the filling is too thick, first give it a good mix, only then add a few tablespoons of water as necessary.
- If used to fill a cake, make sure to fruit filling make so to make a frosting dam around the edges of the cake. This will prevent the filling from coming out of the sides of the cake. See my video, how to level, fill, torte a cake

Yes, you can in fact, I do have lots of other fruit fillings too
Thank you l
How do you know when it’s thick enough ? The longer you cook it, will it continue to thicken ? Ana if it’s a little runny when I place it into the jar to cool, will it continue to thicken as it cools ?
Hey Jennifer. Yes, it does thicken some more as it cools. But, if it’s too liquidy then you can cook it off a bit more before you cool
As promised ~ easy and so delicious! Not sure this is going to make it into any recipe before it all ends up in my tummy!
I hear you, Maria. I have to hide if from my kids too. They can eat this with a spoon out of the jar. Thanks for the feedback
Thanks
You are welcome, Mfon

Regular granulated sugar
What a great recipe, its quick and easy to do. I’ve been looking for a good strawberry jam filling recipe for french vanilla cake I make with home made whipped cream frosting, fresh strawberries and bananas, and this just made the cake absolutely perfect! I can’t wait to try this jam as a filling with other sweets.
Thank you, Manila. So happy you enjoyed this so much. Thanks for coming back to write this feedback
Hi, when you say white sugar do I use powdered sugar or granulated?
Granulated sugar Norma. Thanks
YES! Veena this looks super simple and yummy! Do you happen to know how much this makes? How many cups does it come out to be? I plan to use it to fill a 12in round cake. Thank you so much!
Hey Alison – the recipe card shows it makes approximately 2 cups. You will need to double the recipe to fill a 12 inch round cake. Thanks.
Veena, this sounds amazing and looks fantastic. Love all the colors!
Thank you, Mariya
Hi just wanted to.know if.i.could use this recipe to.make strawberrie and cream my question is how do i make the cream i wanted to make a 5 layed cake will this hold .. And im going to.cover the cake with buttercream thank you
Hey Lisa. You can use this strawberry filling in a cake as a filling – is that your question?
How many layers you make depends on the type of cake you use, and how well you stack them.
I suggest – one layer filling and alternate with one layer buttercream to keep the balance.
Thanks
Hi thank you for.your reply doing 5 layers do i put cream with the strawberry then buttercream around the sides?. Wanted try cream and strawberry with vanilla cake.. How long does the strawberry last can it be left out when i do the cake or i need to.put in the friage i going to cover the cake with buttercream thank you
Lisa. I have explained in detail in the post on how long you can keep it. You can put cream with the strawberry filling but it will not keep the creamy white.
I would spread the cream then layer the strawberries over gently. Or you can pipe a border of cream and add the filling in the middle. Or you can alternate between the two methods
See my strawberry cream cake for more details.
Hi. I don’t know what I did wrong. I made this twice today. It turned out the same both times. I did double the recipe, would that cause it not to set up? I was going to use it for A filling in a vanilla cake tomorrow. It seems drippy and runny. Certainly not thick enough for a cake. I have one batch in fridge but it is still too thin. Help please.
Sounds like you didn’t cook it long enough Susan. Did you use frozen strawberries? If there is too much moisture in the berries you will need to cook it longer to evaporate the excess moisture. See the video for consistency of when to take it off the heat.
