About Chocolate Bar Cake Recipe

Chocolate bar cake is made using basic ingredients which you already have in your house. I made a basic moist chocolate cake and topped it with chocolate bar which served as easy frosting. The main thing you have to take care is placing the chocolate bar while the cake is still hot which make sure the chocolate melts and sticks on top of the cake as a frosting. 

This cake cannot be kept in the fridge because the chocolate on top of the cake might get hard and if refrigerated. This particular recipe is so easy to make and can be served as a snack cake as well. The taste of the cake is ultimate because the frosting is pure chocolate.

Frequently Asked Questions

Which type of chocolate cake is best?

I prefer chocolate cake which has the addition of hot water add in it which wakes the cocoa powder in the cake and makes it so intensely chocolate. This cake is one such recipe.

How do you make a bar cake last longer?

Please do not refrigerate leftover cake; this will dry the cake out and harden the chocolate frosting on top.. For longer storage, you can cover the cake and place it in the fridge. But when serving you might want to warm it slightly in the oven so that the chocolate on top gets creamy again. 

Can egg be substituted in this recipe?

You can use 2 tablespoon of yoghurt instead of 1 egg in this recipe. 

Can wheat flour be substituted for all purpose flour in this recipe?

Yes, wheat flour is used instead of all-purpose flour which still makes the cake moist and tender.

Is brown sugar compulsory in this recipe or can it be interchanged?

Brown sugar can be changed to regular granulated white sugar, just add 1 cup of white sugar instead of one cup of brown sugar.
