SUGAR COOKIE RECIPE WITH BUTTER RECIPES

Steps:

• Cream butter and sugar until light and fluffy, 5-7 minutes. Beat in eggs and vanilla. In another bowl, whisk flour, salt, baking soda and cream of tartar. Gradually beat into creamed mixture. Refrigerate, covered, for 30 minutes., Preheat oven to 350°. On a lightly floured surface, roll dough to 1/4-in. thickness. Cut with floured 2-1/2-in. cookie cutters. Place 1 in. apart on ungreased baking sheets. Bake 10-12 minutes. Cool on wire racks. , For frosting, beat confectioners' sugar, butter, vanilla and enough milk to reach desired consistency. If desired, add a few drops of food coloring. Cut a small hole in the tip of a pastry bag or in a corner of a food-safe plastic bag; transfer frosting to bag. Pipe decorations. Sprinkle with colored sugar.
  Freeze option: Freeze undecorated cookies, layered between waxed paper, in freezer containers. To use, thaw and decorate as desired.

Steps:

• Heat oven to 350 degrees. Lightly butter a 9-by-13-inch baking pan. Line the pan with parchment paper, running it up the two long sides of the pan and letting it extend past the rim by about 2 inches.
• Make the bars: In a medium bowl, whisk together the flour and salt. In a large bowl with an electric mixer, or in the bowl of a stand mixer fitted with the paddle attachment, beat butter and cream cheese on medium speed until well blended, about 1 minute. Add the granulated sugar and beat until smooth, about 1 minute. Add the egg and vanilla and beat on low speed until well combined, about 1 minute. Turn off the mixer and scrape down the bowl with a rubber spatula. Gradually add the flour mixture, mixing on low speed just until blended, about 1 minute.
• Using a spatula, scrape the dough into the prepared baking pan and spread it into an even layer. Bake just until the edges are starting to turn light golden brown, and a toothpick inserted in the middle has moist crumbs, 20 to 25 minutes. (Do not overbake! The bars should be quite moist, and almost slightly underbaked in the middle.) Remove the pan from the oven and set it on a wire rack. Let cool completely. When fully cooled, remove the bars from the pan using the overhanging parchment paper.
• Make the frosting: Place the butter in the bowl of a stand mixer fitted with the paddle attachment. Beat the butter on medium speed until creamy, about 1 minute. Add 1 cup confectioners’ sugar, beating on low speed until fully combined, then repeat with remaining 1 cup confectioners’ sugar. Add the 1 tablespoon milk or heavy cream, 1 teaspoon lemon juice, the vanilla, salt and food coloring, if using, and beat on medium speed until the frosting is light and fluffy, scraping down the sides halfway through, about 4 minutes. Add more milk if needed to thin out the mixture. Add lemon juice and vanilla to taste.
• Using a spatula, spread the frosting on top, then decorate with sprinkles, if using. Cut into 20 bars and serve.
