You can make old-fashioned sugar cookies by using a recipe from the Food Network. This recipe makes approximately 3 dozen old-fashioned sugar cookies depending on the size of the cutters that are used.
Start by creaming 2 sticks of unsalted butter and 1 cup of granulated sugar together in a large bowl using an electric mixer. Beat in 2 lightly-beaten eggs and 1 teaspoon of vanilla extract. Combine 3 cups of all-purpose flour, 2 teaspoons of baking powder, and 1 teaspoon of salt in another bowl and stir the butter mixture and the flour mixture together 1 cup at a time, forming a dough. Refrigerate the dough for three to four hours.
Roll out the chilled dough and cut it into shapes with cookies cutters or a sharp knife. Place the individual cookies on a parchment-lined cookie sheet, brush the cookies with milk using a pastry brush, sprinkle with colored sugar, and bake in an oven preheated at 350 degree Fahrenheit for 10 or 15 minutes or until the edges of the cookies barely begin to turn brown. Remove them from the oven and place them on a rack to cool.
An alternative to sprinkling the cookies with colored sugar prior to baking is making "Royal Icing" to decorate them with instead. To make Royal icing, combine 2 pounds of powdered sugar, 1/2 of a cup and 2 tablespoons of meringue powder, and 3/4 cup of water, and slowly mix with an electric mixer until it forms peaks. Stir in 1 tablespoon of the gel food coloring of your choice and decorate the cookies.
