I see a lot of these cute carousel cakes online and I was wondering where I could purchase the carousel like the one in the pic I had posted. I'm wondering if it comes as a set with some instructions. I'd really like to make this for my Aunt's baby shower.  TIA!

That's handmade out of gumpaste or fondant - in a mold.

Yep all handmade!

If you google "carousel horse mold", you'll find dozens of options from simple chocolate molds to really nice 2.5D silicone molds.
