My son's first birthday is in June, which is the reason I started decorating cakes 4 months ago. LOL

Anyways, my idea is to have a priamry color and shape theme. Like red, yellow and blue with squares, circles and triangles. So to get to the point I want to do his cake with a square base ( I need to get very sharp corners, How??) a circle or ball on top, and his smash cake would be the triangle.

How do I get sharp corners on the square?
What is the best way to ice the ball? poured fondant?
What is a good whipped cream type icing for the smash cake?

If you go to Youtube tonedna(Edna) has some great tutorials for decorating. She has one about square cakes.

Thank you.

I would like to do the triangle cake in more of a whipped icing, does any one know of an icing that i will be able to use that will get smooth?

For whipped icings, I purchase Pastry Pride Vanilla Whipped Topping. You can whip it until it gets pretty stiff. It has smoothed really nice for me and I have piped roses with it as well. There is couple cakes in my photos that have whipped icing, the my little pony cupcake tree and the teal graduation cake, that I remember for sure.

I have always purchased it from Smart n Final.
