Batman Cookies

This was my first attempt using royal icing to make a design on something. The icing didnt go with the cookie very well though.

First of all I drew the design onto the cookie using black royal icing

Then I filled it in with the royal icing.

 It would have been better to make black glacé icing because the royal one doesn't taste nice! 

Then I filled in the yellow part with yellow glacé icing and tada :)
