i am making a boobie cake but am at a loss for how to make the belly button where it looks ok on the cake. it will be covered in buttercream.

my aunt told me she always used a silver button and stuck it into the cake for the bellybutton but i dont know...

any help appreciated...i have to decorate it tomorrow night to deliver friday night

id just do a little bc 'c' shape (or filled in circle, since i guess it shoud be popped out - maybe see what looks right on it!), rather than get too into it, realism is not your friend with this kind of cake (in my opinion).

If you're using a crusting buttercream, just make an indentation in it with your fingertip after the buttercream has crusted.

ditto texas rose

I rolled out a small snake out of fondant and made it into the shape I wanted, then flattened it and put it on the cake.

this post is old.. but i just indented one with then end of a wooden spoon. perfect size. put a little silver ball in.. annnd she had an innie with a belly button ring. =)
