The ancient breakfast cake refers to the cake made of eggs, flour and sugar as the main raw materials, while the cheesecake is a cake with cheese added to the recipe, including but not limited to adding cream.

Ancient breakfast cakes refer to Japanese cakes, but they have different names. Japanese cheesecake is a kind of cake. The main materials are cheese, eggs, flour, milk and so on. This process is baking. Put the egg white and sugar into a dish, and mix them evenly in the same direction with an egg beater until they are as white as whipped cream. Mix cheese, egg yolk, flour and skim milk into a paste. Then slowly pour in the prepared protein foam while stirring for use. When pouring the egg liquid, make sure it is filled with a lot of air. The cooked cake is "puffed" by the principle of thermal expansion and cold contraction.
