Glycerine creates a sheen on cakes, so if you want to bake a shining cake, add a few drops of glycerine to the cake mixture or the icing. There are many types of glycerine, some for cooking and others to make your skin soft, so always get glycerine from food stores and not from pharmacies, which tend to store skincare glycerine. Cooking glycerine is a liquid and it comes in small packages, like food colourings. You can also use glycerine to bake cakes without eggs.
Mix the flour, baking powder, sugar powder and the baking soda together in a plastic bowl.
Beat the margarine and the condensed milk using a blender for 10 minutes in a plastic bowl to get a smooth mixture. Divide the flour and baking soda mixture into three portions and mix the portions into the margarine cream.
Add milk to the mixture. If the mixture is too thick add some extra milk. Add some extra sugar if you want to bake a sweet cake. The condensed milk contains a lot of sugar, so taste the cake mixture for sweetness before adding extra sugar.
Mix the vanilla essence, the glycerine, the cashew nuts and the tutti-frutti into the cake mixture. The glycerine will make the cake fluffy and shiny.
Line the baking tray with margarine and flour and pour the cake mixture into the tray. Bake in the oven for 30 minutes. Check regularly, as the cake may bake faster depending on the wattage of the oven.
If you are using icing, mix two to three drops of glycerine into the cake icing to make it shiny. You can add glycerine to nearly any cake recipe as it is tasteless but gives a shining look to cakes.
