How do you made a cake gel?

Answer 1

Unless you have a specific, unusual recipe in mind, there is no "cake gel" used in the batter of a cake. You may be thinking of gel frosting or icing, which is a type of clear sugar gel used in decorating a cake that has already been baked, cooled, and covered with a buttercream or rolled fondant frosting. There are also various types of fillings, placed between baked cake layers, that could be made in a gel form.

Yet another possible reference might be "Jello Cake," in which liquid "Jello" (a commercial brand of flavored Gelatin) is poured over a baked cake so that the gelatin soaks into the cake, adding color and flavor.

Answer 2

Cake gel is used to add color to cakes or icings. Just a tiny bit of the cake gel should be added to either the batter or icing since it is very concentrated and produces brilliant color.
