The cookie I made before at least 2 1/2 years ago for my youngest sisters baby shower. I used duck cookie cutters and a butter cream icing. Excellent. I wished I could find a picture.
The cookie recipe I found on http://www.marthastewart.com/recipe/ideal-sugar-cookies?autonomy_kw=sugar%20cookies&rsc=header_35 a few years back. It's a cookie that tastes great and not difficult.
The Royal Icing recipes I found at http://www.joyofbaking.com/ .
Royal Icing using Egg Whites:
2 large egg whites
2 tsp fresh squeezed lemon juice
3 cups powdered sugar, sifted
I mixed it all then separated it to use different colors. I used Wilton's Icing Colors, (you can find at most crafting stores that carry Wilton's products).
Then I piped the icing outlining the cookie. After that set I then thinned the icing with a touch of water at a time to the desired consistency. I then placed it in a ziploc bag snipping a very small hole and started to fill in the cookies 1-3 at a time. The icing dries very quickly so you need to work fast. What doesn't fill in take a tooth pick push the icing into place. I made 80 cookies. You can find more info below as well as on youtube if you'd like to see a how to video if you haven't tried this before.
