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
This filling will stay in the fridge for a week but can be frozen in the fridge for up to 3 months. I think you meant freezer lol
Yes, Deb, thank you
Love this! Easy and quick, but so good. I think it is even better the next day which makes it perfect for making ahead when prepping a cake or dessert. I have used this to fill a cake and on top of mini cheesecakes. Thanks!
Yes, Krysta. It is perfect the next day as it thickens even further. Mini cheesecakes sound yum. Thanks for the lovely feedback.
I made this for the 4th of July as a topping for a butter cake that I made and everyone just loved it. I double this recipe and added fresh blueberries a 1/4 of tsp. of vanilla and 1 tbsp. of butter. Thank you so much❤️
That sounds delicious, Robin. Thanks for the lovely feedback.
This strawberry filling looks amazing and is exactly what I’m looking for to use in my chocolate cake recipe. One question, if I use frozen strawberries can they be cooked right out of the freezer or do they need thawed at all?
Yes, stephanie. You can cook it right out of the freezer as it will thaw with the heat. But, frozen strawberries also have excess moisture so you may need more cooking time to make it thick.
Hi there. I was planning to make this recipe but I’m wondering how many cups of strawberries you use in the original recipe? I know it says 7oz so does that mean you only use about 1 cup of strawberries? Thanks!
Ah, yes, I gave a small recipe so people can double but…. I just changed it to one lb batch. I hope that helps.
Hi! I just made this and mine came out too thin. Any advice? Should I just add more cornstarch? Thanks!
Katrena. Just cook it a bit longer so the water evaporates. I don’t like adding too much cornstarch as it makes it too starchy.
Thank you so much!
Hi Veena. Can I mix this filling into whipped cream and use as a filling that way?
yes, you can use it in whipped cream too.
So if this can be kept out for 2 days, does that mean that a cake flower this as a filling can sit out 2 days before needing refrigeration as well. For instance I want to make a vanilla cake with American buttercream, can I fill with this and make it the night before and have it sit out at room temp overnight?
No, all fruit fillings need to be kept in the fridge. The filling can be kept at room temperature for only a few hours. Sorry. Thanks.
This sounds delicious! Two questions: 1. Can this recipe be canned in a water bath? 2. Can Splenda or Stevia be substituted for the granulated sugar? Any help would b3 appreciated!
Hey Becky, Yes, this can be canned in a water bath. Some visitors have used between 2 tbsp to 1/4 cup Splenda for making it. Hope this helps. Let me know how it was if you try it.
Why do think my strawberries look dull in color…not a vibrant red like your photo?
Tina did. you cook until the cornstarch was cooked and the filling when from an opaque to a glossy shine? Sounds like you needed to cook it some more. Watch the video you will see when I add the cornstarch it has a very dull strawberry color but I continue to cook until the cornstarch is thoroughly cooked and it turns into a beautiful transparent glossy shine.
Week 2: Day 3 – DONE
For the Simple Moist Chocolate Cake, I planned to fill and frost with Velvet American Buttercream ~ then I remember this amazing strawberry filling! I’m using frozen strawberries so if I can achieve the right consistency, I’d like to add it to my layers with a dam of velvet ambc.
You can use frozen strawberries – just cook it longer to evaporate the excess moisture so it’s not too wet
