Here’s a dough recipe for semisoft sugar cookies. This recipe makes about 4 dozen cookies.
Preheat oven to 300ºF. In a large mixing bowl, beat softened butter and shortening with an electric mixer on medium to high speed for 30 seconds. Add sugar, baking soda, cream of tartar, and salt. Beat mixture until combined, scraping sides of bowl occasionally. Beat in egg yolks and vanilla. Beat in as much of the flour as you can with the mixer. Stir in any remaining flour.
Using your hands or a cookie scoop, shape dough into 1-inch balls. Place balls 2 inches apart on ungreased cookie sheets. Bake in the preheated oven for 12 to 14 minutes or until edges are set; do not let edges brown. Cool cookies 1 minute on cookie sheet. Transfer cookies to wire racks and let cool.
Tender, sweet sugar cookies make canvases for flavor artistry. Add dashes of new flavors—spices, citrus zest, or extracts—to the dough to make your cookies distinct.

Tips for making easy decorated sugar cookies:
Store your batch of perfect sugar cookies as you would any other drop cookies made with butter and/or shortening: Layer cookies between waxed paper in an airtight container. Store at room temperature for up to 3 days. You can also freeze unfrosted cookies for up to 3 months (frost after thawing).
