Easy Cut Out Sugar Cookies bring me waaayyyy back. My mother, Norma Jean, made these during my childhood, and the memories are flooding in.
In a standing mixer, cream butter and sugar together. Add eggs and vanilla and mix well.
In a separate bowl, combine the dry ingredients - the flour, cream of tartar, baking soda, and salt. Pour into mixer and combine with wet ingredients, mixing until just combined. Don't over-mix.
Scoop dough into an airtight container and store in the refrigerator overnight, or for at least several hours.
Preheat oven to 350 degrees. Prepare baking sheets with parchment paper.
Form the dough into a ball and place on floured surface. Using a rolling pin, roll dough out into thin layer, about 1/4 of an inch.
Take cookie cutter, and cut shapes out of dough. Lift gently onto prepared baking sheets.
Bake for approximately 10 minutes. Remove to cooling racks.
Mix the icing ingredients together and stir until well combined. If the frosting is too wet, add more powdered sugar. If it is too dry, add some half and half (slowly - about 1 teaspoon at a time)
When the consistency is correct, separate into two bowls (the tree outline will take far less frosting so add less to one bowl). Add food coloring to each bowl, placing the one for the tree outline in the decorating kit.
Spread some of the darker green icing on the cookies. Draw a tree with the fluorescent green. and them add sprinkles.
