In a large bowl, beat butter and sugar together in a stand mixer until smooth.
Beat in the vanilla extract and the egg.
Add in the rest of the dry ingredients slowly while beating the dough.
After a while and the dough is stiff, finish kneading by hand.
Roll the dough into a ball, then squeeze the dough into a ¾ inch-thick disk.
Wrap the dough in saran wrap, and chill in the fridge for 2 hours before rolling.
Preheat oven to 350°F.
Roll the dough onto a lightly floured surface to ¼ inch thick, and cut with cookie cutters into desired shapes.
Transfer cookies onto a baking sheet lined with paper or a silicone liner.
Before baking, place the baking sheet of cookie cutouts in the fridge and let chill for 5-10 minutes. This is so the cookies will keep their form and not spread out while baking.
Bake for 8-10 minutes, then cool on a cookie sheet, then transfer to a cookie rack to finish cooling.
In a large bowl, combine confectioner’s sugar and meringue powder.
Add warm water, one spoon at a time, while mixing on low speed.
Add vanilla extract, and continue mixing until the mixture is shiny.
Mix at low speed and beat for 5-7 minutes, and add desired colors.
Transfer to piping bag.
For each color of icing, you need 2 different consistencies of icing. For a thinner consistency, add more water to the mixture. Thinner icings are used for flooding, and thicker icing is used for borders and edges.
For thicker icing, cut the piping bag very thinly, around a 1/16 of and inch. For thinner icings, cut ⅛ of an inch. If this is too small, you can always cut more bag.
After decorating cookies, dry the icing with a craft heat gun 10 inches away, so the flooded icing does not cave on itself.
I like to let my cookies air dry in a cool space for 2 days, then they’re ready for packaging.
The cookies can be frozen in any part of the process: the dough, decorated and undecorated cookies. Decorated cookies must be frozen slowly, placing a cookie on a baking sheet for half an hour, then stacking similar shapes, putting parchment paper in between. Then wrap the stacked cookies in press n’ seal and then aluminum foil, date the cookies, and the cookies stay good for four months.
