After your dough has chilled for at least 4 hours, prepare your work surface. You'll need flour, a couple of cookie sheets lined with parchment paper, a spoon or cookie scoop, and a pre-heated oven.
Using a cookie scoop or a tablespoon, scoop a small ice cream scooped size of dough and sprinkle it with flour. This is important if you don't want the dough sticking to your hands.
Roll the dough into a ball and start to press it flat.
Make it so it has a real wavy kind of funky look to it. The ultimate goal is a puddle. There is no right shape. I like to start it in my hand and then set it on the cookie sheet and press it down until it's about half an inch thick.
Make them all different. Go ahead and repeat that step with each cookie. You'll want to get them as close to the same size as possible but they don't have to be exact.

Bake according to your recipe directions.
While they are baking, go ahead and make your Royal Icing Recipe. I use the Wilton Recipe that has Meringue Powder. If you would like to use this recipe, you can purchase Meringue Powder at a craft store. Here is the recipe I use.
Wilton Royal Icing RecipeIngredients:*
3 tb Wilton meringue powder*
1 lb Sifted powdered sugar*
6 tb Water Preparation
IF using a counter top mixer, beat all ingredients at low speed for 7 to 10 minutes until icing forms peaks.
If you are using a hand held mixer, it will take more like 10-12 minutes.
AFTER you get stiff peaks, you'll want to transfer about 1/2 into a bowl and add a 1/2 a teaspoon of water at a time while stirring until the consistency is slightly runny.
To test for the right consistency: Using a knife, scoop a little of your runny icing and hold above the bowl. As it drips, count to 10. By the count of 10, the icing that dripped down should meld into the icing in the bowl so there is no indication of where your drips landed. Put your icing in a container covered with a wet paper towel and a lid.
