Sponge Cake and Butter Cake, Different Types of Bolu!

For those of you who love cakes, you’re surely no stranger to the term “bolu”, right? Yes, the name referring to this soft-textured cake generally consists of three main ingredients: eggs, flour, and sugar. But do you know where bolu originated from and what its types are?

The term “bolu” is derived from the Portuguese word “Bolo”, which means cake. This cake is made from flour, sugar, and eggs, which are then baked or steamed to cook the batter made from these three basic ingredients.

Once cooked, bolu is usually decorated with a layer of butter and various other toppings, such as chocolate, grated cheese, or fruits. In terms of types, bolu is divided into two: sponge cake and butter cake.

Sponge Cake

As the name suggests, sponge cake has a super soft texture like a sponge. This is because its main ingredients consist of beaten eggs and sugar which create foam or bubbles. After that, melted butter or cooking oil is added.

That’s why the main ingredient used as a leavening agent in making sponge cake is eggs, not baking powder like in other types of cakes. Although it is very soft, sponge cake is considered a dense type of cake.

The softness of sponge cake is also thanks to the appropriate temperature when baking. To achieve the perfect texture, sponge cake is usually baked at a temperature of 180-200°C. Not only that, but the depth of the baking pan should also be carefully considered.

Remember, too high a temperature can cause the outer part of the cake to cook too quickly and become dry, while the inside remains raw. Some common sponge cakes found in Indonesia include plain cakes with chocolate or cheese flavor and fruit-filled roll cakes.

Butter Cake

The second type of cake is butter cake, which relies on baking powder as a leavening agent in its preparation. This is because butter cake consists of the main ingredient, butter, beaten with sugar.

Not only that, but the texture of butter cake is denser than sponge cake. Therefore, if you store butter cake for too long at room temperature, it will become dry. However, don’t worry, as long as the margarine measurement and baking temperature are correct, there’s no doubt about the taste.
