Gâteau Chocolat

In Japan, the confection called “gâteau chocolat” is best known as a dense, round baked cake with a rich chocolate flavor. Cracks form on its surface, and some are finished with a dusting of white powdered sugar. The French term gâteau au chocolat is a broad name for chocolate cakes of all kinds. Depending on the foam in the batter, the balance of flour and fat, and how the center is made, cakes with the same name differ in both method and result.

How Cacao Content, Proportions, and Egg Foam Change the Result

Chocolate contains not only cocoa solids but also cocoa butter and sugar. Cocoa powder, by contrast, is an ingredient from which part of the fat has been removed. Substituting one for the other by equal weight changes even the proportions of fat and sugar in the batter. Switching to a chocolate with a higher cacao percentage does not necessarily produce the same tenderness. The stated cacao percentage is a guide to flavor, but the moisture and sweetness of the cake as a whole also depend on how it is balanced with the other ingredients.

Meiji’s published recipe (ingredient proportions and method) uses milk chocolate together with cocoa, and uses the egg yolks and whites separately. The chocolate and butter are melted and combined with the yolks, cream, and dry ingredients, and then meringue whipped separately is added. Mixing in a small first portion loosens the heavy batter, so the remaining meringue can be blended in evenly with fewer strokes. This is why the first portion and the remainder are added separately.

The cake rises as it bakes, and as it cools it may sink slightly, leaving a dense interior. With this method, cracks may also form on the surface. Because the fat in the chocolate sets as it cools, warm cake and a cold cut surface also differ in firmness.

There are also methods in which the whites are not whipped separately and beaten whole eggs are added instead. The cooking expert Harumi Kurihara creams butter and sugar, then combines whole eggs, melted chocolate, and the dry ingredients in that order before baking. She explains that with this formula, the flavors meld and the cake becomes moister on the day after baking.

Making a Flowing Center Separately

Valrhona has a recipe for coulant au chocolat in which a melting chocolate filling is placed inside an outer batter made with lightly whipped whole eggs and then baked. A flowing center is not necessarily made by leaving the whole cake underbaked. By making the outer batter and the insert for the center separately, the outside sets in the oven while the center stays soft enough to flow.

Names such as fondant, moelleux, and coulant relate to softness, but makers use them in varying ways. Some have cream sandwiched inside and others are covered in glaze, so even under the same name, the formula and the filling differ.

Comparing Formula and Texture with Brownies

Round gâteau chocolat and square brownies differ in many ways, not only in shape but also in formula and texture. Some gâteau chocolat are made with whole eggs, and brownies range from dense to light. King Arthur’s baking guide also describes brownies made with more flour and eggs, with added liquid and leavening, to give a crumb closer to that of a cake.

The combination of how the eggs are whipped, the ratio of fat and chocolate to flour, the depth of the pan, and when the baking is stopped changes the density and softness. French cakes include methods other than separating the eggs, and some brownies use leavening. The crumb seen in a cut slice changes according to how these ingredients are handled.

Cakes That Showcase the Batter, and Cakes Layered with Jam and Glaze

In contrast to cakes enjoyed for the chocolate batter itself, some cakes are completed by adding layers after baking. Vienna’s Sachertorte combines a chocolate sponge with apricot jam and a chocolate coating. This construction adds the acidity of fruit and the different mouthfeel of the glaze to the sweetness and bitterness of the sponge. The approximate home recipe published by Hotel Sacher also shows the steps of spreading jam on the sponge sliced horizontally and pouring over a sugar syrup and a chocolate coating.

There are cakes leavened with meringue, coulants that enclose a separately made flowing filling, and tortes layered with jam and glaze after baking. Even among chocolate cakes, they differ in whether softness is created within the batter or by combining different layers. The rich baked cake familiar in Japanese as “gâteau chocolat” can be described as one member of this broad family that is enjoyed for the texture of its crumb and the way it melts in the mouth.

From Drinking Chocolate to Baked Goods

In older English, the phrase “cake of chocolate” also had a meaning different from today’s. In 18th-century English, it could refer to solid chocolate used to make a drink. The Baker company, which began manufacturing in the United States in 1765, also initially sold solid chocolate for drinking. In the English of this period, “cake” had a meaning separate from baked goods.

Meanwhile, 18th-century France had recipes that added chocolate to a baked batter of eggs and flour. A 2024 exhibition at the Bibliothèque Sainte-Geneviève featured such a biscuit described in Menon’s La Cuisinière bourgeoise, and noted that the same recipe was also included in the 1778 edition of Les Soupers de la cour.

In the 19th century, the technology for producing the ingredients, and the way they reached people, changed. In 1828, the hydraulic press used by Casparus van Houten in Amsterdam separated cocoa butter from cocoa paste and opened the way to producing powdered cocoa more cheaply. The company began selling it in tins in 1865. Today’s choice between a powder with part of its fat removed and chocolate that also contains sugar and fat is bound up with this history of manufacturing and commercialization.

Baker’s 1886 cooking booklet also featured cakes and macaroons alongside beverages. Together with the spread of ingredients and tools, publications that taught households how to use chocolate broadened its uses beyond drinks and coatings. The rich gâteau chocolat so familiar in Japan is likewise one of the many varied cakes made with chocolate.
