I want to make the Chocolate Buttercream Birthday Cake.

But I have no idea. So give me some idea of making this cake.

Also say that how to decorate this cake?

Thanks for help in advance.

You might need to provide a bit more information. Do you have a picture of a cake you might like to copy?

AWhat?

Of course.

I am sending the picture of that type of cake.

Now you can try to give the answer.

You'll need to find a recipe for chocolate buttercream - this site has a number.

The buttons are made with brown fondant, or modelling chcolate. There are button moulds you can buy, or you can use circle cutters and put a rope of fondant on the top. The letters are made with funky tappits.

The shell piping is made with a star tip in a piping bag - google piping borders and you should find a video that will be helpful.
