Between Cake Layers: Filling vs Frosting and Their Roles
In the world of cake decorating, the concept of fillings versus frosting can often be a bit confusing for bakers. While many know that the outside of the cake is frosted, it's not uncommon for bakers to use a different substance between the layers. This article delves into the types of fillings commonly used between cake layers, their purposes, and how they affect the overall taste and texture of the cake.
Common Types of Fillings Between Cake Layers
When it comes to filling the space between cake layers, bakers have a range of options tailored to their desired taste and texture. While frosting is a plausible choice, it's not always the ideal option. Here are some popular fillings used between cake layers:
Buttercream
Buttercream is a versatile frosting that is often used as a filling. By adjusting the ingredients and cooking method, it can be made with different textures and flavors, catering to various preferences. Its creamy consistency makes it an excellent choice for adding richness and moisture to the cake.
Fruit Preserves or Jam
Fruit preserves or jams add a fruity dimension to the cake while also providing moisture. Thesejams can be homemade or store-bought, offering a natural sweetness and flavor that complements the cake layers.
Pastry Cream
Pastry cream is a custard-like filling that is rich and creamy, often used to balance the dense nature of some cake layers. Its smooth consistency and subtle sweetness can enhance the overall taste profile of the cake.
Ganache
Ganache is a chocolate filling made from melting chocolate and cream. It can be poured or spread, making it a versatile option for different cake designs. Its smooth, glossy finish and intense chocolate flavor can elevate the baking experience.
Cream Cheese Filling
Cream cheese fillings provide a tangy flavor that pairs well with various cake flavors, such as vanilla or lemon. Its creamy texture also offers moisture and stability to the cake layers.
Mousse
Mousse is a light and airy filling made from whipped cream and sometimes flavored with chocolate or fruit. Its frothy texture and delicate flavor make it a popular choice for special occasion cakes.
Why the Middle Layer Might Taste Different
While the filling and frosting are often made from similar ingredients, there can still be differences in taste and texture between the middle layers and the outside of the cake. Several factors can contribute to these differences:
Moisture Retention
The middle layers are sandwiched between the cake and the filling, which means they don't dry out as quickly as the exterior. This can result in a moister and more flavorful center, as the layers are better preserved.
Absorption
The pressure exerted by the weight of the cake can cause the filling to be slightly absorbed into the cake layers, making them taste more tender. This absorption can also enhance the flavor as the ingredients merge.
Cooling Time
If the layers are not fully cooled before adding the frosting, it can alter the structure and taste of the cake. A cake that is not adequately cooled before frosting can lead to an inconsistent texture and flavor.
Cutting and Discarding
In professional bakeries, it's common practice to slice off and discard the bulging mound portion of the bottom layer. This ensures that the added layer on top sits flat and secure. As a result, the frosting in the middle is more absorbed into the exposed layer, changing its taste and texture.
Conclusion
When considering the types of fillings between cake layers, bakers have a wide range of options to choose from. From the fruity richness of jams to the luxurious smoothness of ganache, each filling adds unique flavors and textures to the cake. Understanding the differences in taste and texture between the middle layers and the outside frosting can also help bakers achieve the best results in their cakes.
