The "watercolor" is just gel food coloring, thinned with a bit of vodka. You can also use water but vodka is my preference since the alcohol evaporates more quickly and reduces your risk of getting the cookies too wet and dissolving the icing base coats. Usually when I paint cookies, I use thinned royal icing which creates a more matte look.
The only real trick to making these is to be absolutely certain that your base coat of royal icing is completely dry before you start painting. If it's not fully dry, it will crack and begin to dissolve from the paint.
Once the painting dried, I piped some heart details with medium consistency red royal icing, using a bag fitted with a number #1 tip.
So bake some cookies, flood them with royal icing, let them dry, choose your colors and let your creativity flow! It's so satisfying!
Here's how I painted mine, but you should paint yours anyway you like — Experiment and have fun!
|Go for it by adding the colors one at a time, with a soft brush. Don't overload your brush because the paint goes farther than you think.|
|After adding the pinks, I decided to let the cookies dry a bit before moving on. It's important that you don't get the cookies too wet.|
|I decided to add some piped details to mine, but they looked nice without it too.|
|Let the cookies dry completely before packaging or serving.|
