Preheat the oven to 375. Line baking sheet with parchment paper. Cream butter and sugar in a mixer til fluffy. Add eggs and milk and beat til combined. Scrape down often.
In a bowl combine flour, salt, and baking powder. Add to wet ingredients in about 3 batches. This is where you add anything you want or not if you just want sugar cookies. Scrape down to a ball in the mixing bowl and put in the freezer for at least 30-45 minutes. I dont even cover it.
When thoroughly chilled, on a floured surface, roll dough into a log.
Cut your dough into rounds and reshape into circles OR just roll it out like regular cooky dough and use cutters. I chose the log this time. Put remaining dough in the freezer til the next batch.
Bake on cookie sheet for about 13-15 minutes. Only the bottoms should be slightly brown. Let cool on a rack.
I made a chocolate glaze with 1 cup powdered sugar, 2 heaping tbsp cocoa powder and enough milk to make it thick.
