This is my MIL's Rolled butter cookie recipe:
1 lb (4 sticks) butter or margarine, softened
5 c. flour (scant)
2 c. powdered sugar (plus more to roll it out on)
2 Tbsp milk
2 Tbsp vanilla
Oven at 325
Grease (or parchment paper) cookie sheet
Mix ingredients. Roll out THICK
using powdered sugar (NOT FLOUR) on the rolling pin and surface.
Cut into desired shapes w/ cookie cutters.
Bake 20 minutes--DO NOT BROWN.
I do an outline of royal icing on them--that's optional.
But what's a must is to glaze or frost them. we usually just glaze-- powdered sugar + water (or milk) + vanilla + food coloring = glaze--I don't really have a recipe, just until it looks right (and sprinkles on top)
Here's a picture, if it helps
(this is how you do the outline and flood: http://www.sweetsugarbelle.com/blog/2011/07/outlining-and-filling-cookies-with-royal-icing/
except I like the plain sugar glaze we use better than the 'real' kind
And you can add cocoa powder to the glaze to make brown chocolate ones
