Sugar Cookies with Royal Icing decorated to look like tacky Christmas sweaters!
Preheat oven to 350°F. In a medium bowl, add flour, baking powder & salt (measuring the flour with a scale is the most accurate). Using a whisk, stir to combine and get the lumps out. Set aside.
In a large bowl, add butter and sugar. Beat with an electric mixer for 3 minutes. Add the egg and vanilla and beat another minute. With the mixer on low, gradually add the flour mixture.
Blend until the dough begins to pull away from the sides of the bowl. Take the dough out of the bowl and place on a large piece of parchment paper. Use your hands to knead the dough for a few minutes. Divide the dough into two sections and wrap with parchment paper. Let chill in the refrigerator for about 30 minutes.
To roll dough, place another piece of parchment paper on top of dough and roll with a rolling pin until the dough is between 1/8" and 1/4" thick. Cut into shapes and remove the excess dough. Don't move the shapes, leave them where they are and place on a cookie sheet. Bake for 10-13 minutes or until slightly golden brown around the edges. Let them cool and decorate with royal icing (or you can freeze them before decorating and keep them for several months). Makes 20 (3" cookies).
Place all ingredients in a large bowl and beat with an electric mixer on low for 6 minutes. It will be very thick and fluffy. Add 4-5 tablespoons of water and mix to combine. That's your medium consistency (it should be like toothpaste). Take half the icing and put in another bowl. Add another 1-2 tablespoons of water to that to make the thinner consistency. It should run off the spoon like Elmer's glue. That is your flood consistency. Divide and color as desired to decorate the cookies. Add medium consistency icing to a piping bag, cut a tiny tip off and pipe an outline around the outer edge of the cookies. Then fill in with flood icing. I poured my flood icing into a plastic squeeze bottle to make it easier to distribute but you could also use a piping bag, if you wish. Let dry about an hour, then add decorations with the medium consistency icing.
