Let's face it, when we reach for a slice of cake, it's the cake filling that we look forward to. Nothing transforms a cake from being merely decent to almost magnificent like a generous scoop of sweet, creamy cake filling. In this blog, we will discover the 14 types of cake fillings that can elevate your cakes.


What Are Cake Fillings?

Cake fillings are thick or thin mixtures that are placed between the layers of a cake. These concoctions give flavor and height while also helping to hold the cake's layers together.


Types of Cake Fillings


Here are the 14 different types of cake fillings that are used in cakes, ranging from popular ones to not-so-popular ones:


1)  Buttercream Fillings

Buttercream is simple to use. Given that it's used to cover a cake, using it as a filling simply makes sense.

Buttercream comes in a wide variety of flavors, however, the most widely used ones are chocolate buttercream and swiss meringue buttercream. Remember that you don't have to cover the exterior of the cake with the buttercream you use for the filling. Feel free to change it.


2)  Custard Filling

Custard is a smooth, pastry cream filling. It is made from flour, sugar, cornstarch, and egg yolks. Although custard filling can be found in a wide range of flavors, vanilla and chocolate are the most common ones.


3)  Whipped Cream

Whipped cream is another filling that is frequently used in cakes. This type of cake filling is popular among beginners. For a simple twist to your regular whipped cream filling, simply incorporate melted chocolate to give it a delicious chocolate flavor. This type of cake filling pairs beautifully with a vanilla cake and a dark chocolate cake.


4)  Frosting

Cake frosting is the most common filling used in birthday cakes. If your cake is too dry, use frosting to restore it. This type of cake filling contains butter, milk, and powdered sugar. 


5)  Chocolate Ganache

Ganache is a velvety concoction of chocolate and heavy cream that goes well with a variety of cakes. By increasing the chocolate-to-cream ratio to 1.5 parts chocolate to 1 part cream, you can create a rich, delicious ganache.


6)  Fruit Fillings

There are several fruits that can be made into a filling for cakes. Some of the commonly used fruits include blueberries, apricots, strawberries, peaches, raspberries, and rhubarb.

When using fruit fillings, a dam of frosting is piped on top of the outermost layer of the cake to keep the filling in the space between the layers. Although it is possible to stack fresh fruit between the layers, this kind of cake should only be put together shortly before being consumed.


7)  Cream Cheese Filling

What makes cream cheese frosting so well-liked is its tart flavor. Although it is commonly referred to as a beaten buttercream frosting, the majority of the fat is made up of cream cheese rather than butter.


8)  Mascarpone Cream

Mascarpone has a unique quality that makes it perfect for almost every type of layer cake. This type of cake filling is similar to cream cheese but smoother, sweeter, and less acidic.


9)  Curd Fillings

Curd can be used as a filling on its own or combined with buttercream to impart a unique flavor. Common flavors of curd filling include lemon curd, blueberry curd, and strawberry curd.


10)  Jam Fillings

Jam fillings perform well when mixed with other fillings like buttercream or ganache. Before using it as a filling, simply whisks the jam to soften it, or heat it just a little if it's too thick. For a smoother texture, you might also want to strain the jam to get rid of the seeds.


11)  Ermine Frosting

Ermine frosting is also referred to as "boiled milk" icing. This type of cake filling is light and fluffy and has a texture similar to whipped cream.


12)  Nut Fillings

If you like nuts, a delicious nut cake filling is a great option. This type of cake filling goes well with a chocolate chip cake or a banana cake. The essential components of nut fillings are often butter, sugar, flour, and cream, along with any additional nuts of your preference.


13)  Bavarian Cream

Bavarian cream is not the simplest cake filling to prepare. However, it is among the most satisfying. It is perfect for use in no-bake pastries due to its silky, pudding-like consistency, mild vanilla flavor, and medium consistency between custard and frosting.


14)  Syrups and Glazes

Although they don't provide any thickness, glazes, and syrups can also be used as fillings. They add flavor and help the cake retain moisture. Unless the cake needs to be refrigerated, this type of cake filling can be stored at room temperature.


15)  Mousse

Mousses are airy, delicate, and velvety. When using it as a cake filling, the most crucial consideration is that the cake you select shouldn't be excessively dense. You don't want anything to press the airy, delicate mousse out the sides of the cake and weigh it down.
