These are a very traditional holiday cookie.
Caveats: (1.) you need a cookie press to make these.; (2.) I probably should have glazed them or dipped them in melted chocolate for additional pretty.
Preheat your oven to 350 degrees.
Cream 1 and1/2 cups butter and 1 cup sugar. Mix in 2 large egg yolks, 1/4 teaspoon salt, 1 tablespoon of vanilla and almond or lemon extract, and 3 and 3/4 cups of flour. This is a totally basic dough. It might be fun to try chocolate and espresso flavorings, mint, or whatever.
Load the dough into the cookie press and them about 1 inch apart of a cookie sheet (not parchment or buttering required). Sprinkle with colored sugars. Bake for 7-10 minutes, until the edges show light brown.
If you would rather glaze or dip them: after they are cool, dip them ½-way in melted chocolate or brush with a citrus glaze (mix together 2 cups confectioners’ sugar with 2 tablespoons finely grated lemon or lime or orange zest, plus 1/3 cup fresh lemon or lime or orange juice).
