How To Decorate Tropical Cookies with Edible Watercolor (Cookie Art Club Premium Tutorial)

A set of cookies decorated to look like a tropical scene containing a rainbow watercolor heart, two flamingos facing each other, and three plumeria underneath the heart and the flamingos.

Here's another design that was inspired by one of my daughter's outfits! These tropical cookies are based on a t-shirt with a similar scene.

Here's the shirt that inspired these tropical cookies. I decided to paint them with edible watercolor rather than mix the colors into the icing and pipe them onto the cookies.

I find that with painting I have a lot more flexibility with the colors than I do with piping. It's also easier to blend them and it saves time because I don't have to mix up all those colors and fill the bags!
