Why You’ll Love This Raspberry Cake Filling

This filling is a dream for bakers of all skill levels. It comes together with a handful of ingredients and doesn’t require any fancy equipment.

Can I Use Frozen Raspberries for Cake Filling?

Absolutely! Frozen raspberries work wonderfully in this recipe. In fact, they’re often more economical and available year-round. Just make sure to use unsweetened frozen berries, and you don’t even have to thaw them before cooking. The cooking process will break them down just like fresh ones.

Ingredients for the Easy Raspberry Cake Filling

This raspberry filling is made with simple pantry ingredients but delivers big flavor. Here’s what you’ll need:

Raspberries: The star of the show. You can use fresh or frozen berries, and they’ll create a rich, fruity base.

Sugar: Essential to balance the tartness of the raspberries. Adjust to taste depending on how sweet your berries are.

Cornstarch: Acts as a thickener to create a jammy consistency perfect for filling.

Lemon Juice: Brightens the flavor and enhances the natural tartness of the berries.

Water: Helps dissolve the cornstarch and gives the filling a smoother texture.

How To Make the Easy Raspberry Cake Filling

Step 1: Combine the Ingredients

In a saucepan over medium heat, combine the raspberries, sugar, and lemon juice. Stir occasionally as the berries begin to break down and release their juices.

Step 2: Make the Slurry

In a small bowl, mix the cornstarch with water until completely smooth. This step prevents clumping in your filling.

Step 3: Thicken the Filling

Pour the cornstarch slurry into the raspberry mixture while stirring continuously. Continue to cook for another 1 to 2 minutes until the filling thickens to your desired consistency.

Step 4: Cool and Store

Remove from heat and let the filling cool. For a smooth finish, strain through a fine mesh sieve to remove seeds. Once cooled, store in an airtight container in the fridge for up to a week.

Serving and Storing Raspberry Cake Filling

This filling serves enough for a two-layer 8-inch cake or about a dozen cupcakes. You can easily double the recipe if needed. Once cooled, keep it in the fridge in a jar or sealed bowl. It also freezes well for up to three months, making it easy to batch prep for future baking days.

Use it between cake layers, swirl it into cheesecake batter, or spoon it into thumbprint cookies. You can even stir it into yogurt or layer it into a breakfast parfait.
