I am making a cake this weekend and was thinking of using a "cookie royal" to pipe the Mario character on to parchment then put it on the cake after the cake is decorated. I am just worried about the royal melting. I do use a little different recipe than most as I add cream of tarter to my cookie royal to help it harden in our humid environment (south Louisiana) I know someone out there has to have tried this before please let me know if it worked for you or it there are any tips or tricks that could help me have success. Thank you for you in sites!
