Control Over Texture and Consistency

Better for Your Budget

Opting for homemade over store-bought filling is often much friendlier for your wallet. You likely already have most of the ingredients on hand. Making your own allows you to avoid expensive bakery or specialty store prices.

Essential Ingredients for Strawberry Filling

Making delicious strawberry cake filling doesn’t require a long list of ingredients. Here’s an overview of what you’ll need:

Fresh or Frozen Strawberries

The star of this filling, strawberries provide the delicious fruity flavor. You’ll need about 2 cups of diced strawberries. Go with fresh, ripe berries when they’re in season for best results. Or use thawed frozen strawberries any time of year.

Granulated White Sugar

About 1/2 cup of regular granulated sugar adds the sweetness needed to balance out the berries’ natural tartness. White sugar also helps thicken the filling.


2-3 tablespoons of cornstarch (depending on how thick you want the filling) helps bind the ingredients and enables the filling to thicken to a spreadable consistency.


A small amount of water (1/4 cup or so) provides the liquid base that will become the luscious filling once thickened.

Lemon Juice

A bit of freshly squeezed lemon juice (from about half a lemon) adds bright acidity that balances the sweetness and enhances the strawberry flavor.

With just these simple ingredients, you have everything you need for fresh, homemade cake filling.

Helpful Tools for Preparing Strawberry Filling

You don’t need any special equipment to whip up a batch of strawberry cake filling. However, having these basic kitchen tools on hand will make the process smoother:

  • Small saucepan – For cooking the filling on the stovetop. A 2-quart size works well.
  • Wooden spoon – For stirring the filling frequently as it cooks and thickens.
  • Measuring cups and spoons – For accurately measuring out the ingredients.
  • Mixing bowl(s) – For holding the sliced berries and mixing the cornstarch and water before cooking.
  • Knife and cutting board – To slice and dice the fresh strawberries into smaller pieces.
  • Potato masher or fork – To lightly mash some of the berries to release more juice.
  • Rubber spatula – For scraping all the thickened filling out of the pan.
  • Fine mesh strainer – To remove seeds, if desired. (Optional)
  • Storage containers – Sealable jars, plastic containers, or zipper bags to store the cooled filling for later use.

As long as you have these basic kitchen tools, you’re ready to make homemade strawberry filling!

Step-by-Step Guide to Preparing Strawberry Cake Filling

Once you have your ingredients and tools, it’s time to start preparing your strawberry cake filling. Follow these easy steps:

Step 1 – Wash, Hull, and Dice the Strawberries

Start by giving the strawberries a thorough rinse under cool water. Remove the green stems and leaves from each berry. Then pat the strawberries dry thoroughly with paper towels or a clean dish towel. Dicing the berries into 1/4 to 1/2 inch pieces will allow them to cook evenly. Slice larger berries in half before dicing.

Step 2 – Make a Cornstarch Slurry

In a small bowl, whisk together the cornstarch and cold water until dissolved and smooth. This cornstarch slurry will help thicken the filling later.

Step 3 – Combine the Strawberries, Sugar, and Cornstarch Mixture

Add the diced strawberries and sugar to a medium saucepan. Pour the cornstarch slurry over the strawberries and stir to combine. Let this mixture sit for at least 15 minutes so the strawberries start releasing their juices.

Step 4 – Cook the Filling

Set the pan over medium-low heat. Stirring constantly with a wooden spoon, cook until the filling starts to bubble and become translucent. Then reduce heat and simmer for 2-3 minutes more until nicely thickened.

Step 5 – Stir in the Lemon Juice

Once thickened, remove the pan from the heat. Stir in the freshly squeezed lemon juice. This adds bright flavor and balances sweetness.

Step 6 – Let Cool and Store

Transfer the filling to a bowl and let cool completely, then seal and refrigerate until ready to use. The filling will thicken further as it cools. Store in the fridge for up to 1 week or freeze for up to 3 months.

And that’s it – you’ve made fresh, homemade strawberry cake filling from scratch! The whole process takes just 15 minutes of active cooking time. Now let’s go over some pro tips for success.

Tips and Tricks for Perfect Strawberry Filling

Follow these tips to help ensure your homemade strawberry cake filling turns out perfectly smooth, thickened, and flavorful:

  • Use ripe, juicy berries when possible for the most flavor. Taste a berry – it should be sweet, not tart.
  • Toss in a few slightly under-ripe berries, which contain more natural pectin to aid thickening.
  • Mash about a cup of the berries with a fork or potato masher to release more juices.
  • Stir the filling frequently as it cooks to prevent scorching on the bottom of the pan.
  • Simmer on medium-low heat and don’t let the mixture boil, which could make the filling runny.
  • Chill the filling completely before using, as it will continue thickening as it cools.
  • For a smoother consistency, pass the cooked filling through a fine mesh strainer.
  • Add a teaspoon of lemon zest along with the juice for an extra pop of flavor.
  • Use granulated white sugar or berry sugar rather than brown sugar, which could discolor the pink hue.

Following these tips will help you achieve strawberry filling with the perfect lush texture and balanced sweet-tart taste every time.

Creative Ways to Use Strawberry Cake Filling

This versatile strawberry filling adds fruity flavor to so many desserts and breakfast dishes. Here are just a few ideas for using your homemade filling:

  • Fill a layer cake by spreading the filling between cake layers of vanilla, chocolate, white, or even strawberry cake.

Storing and Freezing the Strawberry Filling

Leftover strawberry cake filling keeps well in the fridge or freezer. Here are some storage guidelines:

  • Place the cooled filling in an airtight container in the refrigerator for up to 1 week.
  • For longer storage, spoon the filling into freezer bags or containers, seal, label, and freeze for up to 3 months.
  • Thaw frozen filling overnight in the refrigerator before using.
  • Don’t freeze pre-sliced strawberries more than 2 months, as they’ll lose texture.

With proper storage, you can enjoy homemade strawberry cake filling for months to come! No more wasting leftover filling.
