• How to Make Christmas Light Sugar Cookies
• In the mixing bowl of a stand mixer, using the whisk attachment, add the Butter, Sugar, Vanilla, and Egg, and blend until light and fluffy.
• In a separate bowl, add the Flour, and Baking Powder, and stir well to blend.
• Add the flour a little at a time and mix on low to blend, until all the flour is added.
• Remove the Whisk attachment, and use the paddle.  Continue to blend the Cookie dough until it's completely blended and a smooth ball starts to form.  Scrape down the mixing bowl as needed.
• Forming the cookies:
• Line two cookie sheets with Parchment paper, and roll the cookie dough into small balls, about 1 inch balls, and place the balls on the Parchment paper.
• Bake at 350 degrees for about 15 minutes, or just until the cookies start to turn a light golden brown around the edges.
• About halfway through baking the cookies, check the oven, and the cookies may have started to crack a little.
• Take a flat bottom glass, dip it in Sugar before lightly applying it to each cookie - smash the cookies very gently, and slightly, making them a little flatter, and spread out a little more.  This will give the cookies a crinkle look.
• When the cookies are done, remove them from the oven to a wire rack to cool completely.  While cookies are cooling, make the Frosting.

Frosting:

• Add the Powdered Sugar to a bowl, and add the milk a little at a time.
• Stir well while adding the Milk, until the Frosting is smooth, and no lumps are visible.
• If the Frosting is thin, add a little more Powdered Sugar until it's thick enough to ice the Cookies.
• When you have the right consistency, place a couple of Tablespoonfuls in a separate bowl, and add a drop or two of the Black Food Coloring Gel.
• Stir well to blend, and if the Black Frosting is thinned a little, add a little Powdered Sugar to achieve a thicker consistency.
• Frost the Cookies with the White Frosting, and allow them to sit for about 45 minutes until the Frosting is set on the Cookies.
• Place the Black Frosting in a pastry bag with the small tip, and pipe the Black Frosting onto the White Frosting, using a back and Forth motion, to resemble a string or strand for the Lights.
• Place the mini M & M's along with the Black Frosting, so it appears as a strand of Colored Lights on the Cookies.
• Serve, and Enjoy!
