Rainbow Pinwheel Sugar Cookies: Prep Time: 30 min. Total Time: 1 hr 30 min. Servings: 14 large cookies. Ingredients: 1 17.5 oz bag Betty Crocker Sugar Cookie Mix, mixed according to package directions Liquid food coloring, as desired Rainbow sprinkles, if desired Directions: 1 Preheat oven to 350 degrees. 2 For rainbow pinwheels, divide dough evenly into five bowls, and color each with a different color liquid food coloring. (We used McCormick Neon shades in pink, green, blue and purple, as well as the yellow from the standard pack). 3 Roll each color dough into 14 grape-sized balls. 4 Combine a ball of each color and quickly roll into a larger ball. It will look like a little beachball. 5 Then roll that ball between your hands and the counter or cutting board until you have a cylinder about 6 inches long. 6 Starting from one end of the cylinder, roll the dough into a coil, twisting the cylinder as you go. 7 Roll edges of the cookie in sprinkles. 8 Repeat with remaining cookies. 9 Bake the cookies for 10 to 11 minutes, or until done (fully done middle with the barest touch of golden brown on the edges).
