Making a layer cake at home may seem difficult at first, but following the steps in the right order can make it an enjoyable process. The key is to time two preparations well: the sponge cake and the filling. Here are practical tips for getting the sponge to rise, choosing a pan, selecting a filling, and assembling the cake.
Secrets to Making Sponge Cake
The first and most important step in making a cake is the sponge; the cake’s ability to hold its shape largely depends on it. Sponge cake is generally made from eggs, sugar, flour, milk, fat, and ingredients such as vanilla.
Use room-temperature ingredients; this small detail can make a significant difference. Cold eggs or milk can prevent the batter from rising evenly. Beat the eggs and sugar until the mixture has grown noticeably in volume and become pale yellow and velvety. Sift the flour and fold it in gradually without overmixing; overmixing develops the gluten and can make the sponge tough.
The most reliable way to check whether the sponge is baked is to insert a thin toothpick into the center. If it comes out clean, the cake is ready. Do not turn the pan upside down as soon as it comes out of the oven. Let it rest in its own heat for a few minutes, then remove the cake from the pan and let it cool completely on a wire rack. Removing it while hot can cause it to collapse.
Choosing the Right Pan and Baking
For a layer cake, use a straight-sided cake ring rather than a standard tube pan with a hole in the middle. Line the bottom of the ring with parchment paper before adding the batter so the baked sponge releases easily. Set the cake ring on a baking sheet and place it in a preheated oven. Keeping the oven door closed during the first half of baking is important for an even rise.
Choosing a Filling: Whipped Cream, Buttercream, or Pastry Cream
You can prepare the filling while the cake bakes; the choice is entirely a matter of taste. Whipped topping is the easiest option and is often sold as a prepared powder. Simply beat the powder with cold milk until thick. You can use it both between the cake layers and to decorate the outside.
Buttercream is made by beating room-temperature butter with powdered sugar for an extended period, and it works both inside and outside the cake. Pastry cream is made by whisking milk, sugar, eggs, flour, and starch continuously while cooking on the stovetop until it reaches a pudding-like consistency. Unlike the other fillings, it is used only between the layers and not on the outside.
Layering and Assembling the Cake
Do not slice the sponge until it has cooled completely; otherwise, it may crumble and the filling layers may not sit evenly. Cut the cake horizontally into 2 or 3 layers of equal thickness. Spread a moderate amount of filling between each layer, keeping it from reaching the edges and leaving the center slightly higher. This helps prevent the filling from squeezing out when the weight of the top layer settles onto it.
Moistening the Cake Layers
A step that gives a layer cake its moist texture is lightly moistening the layers. Brush each sponge layer with a thin coating of cooled syrup made by boiling sugar and water, or with a milk-based mixture. Too much liquid can make the cake fall apart, so brush gently and divide the mixture evenly among the layers.
Storage and Serving
Do not leave a cake covered with cream at room temperature; store it in the refrigerator. Take it out about half an hour before serving so it can soften slightly. Cakes with syrup-soaked or fruit layers benefit from resting in the refrigerator overnight, which helps the flavors between the layers come together.
