Cream together the shortening, butter, vanilla, and sugar.
½ cup unsalted butter, ½ cup shortening, 1 cup sugar, 1 teaspoon vanilla extract
Next, mix in the other cookie ingredients. Mix until well incorporated (do not over mix).
3 large eggs, 3 ½ cups all purpose flour, 1 teaspoon baking soda, 2 teaspoons cream of tartar
Chill for at least one hour.
Form cookie dough balls and place on a well greased or parchment lined baking sheet. Bake for 8 to 10 minutes or until edges are golden. Let rest for five minutes on the baking sheet then transfer to a wire rack to cool completely.
For the frosting
While the cookies are cooling, mix together the ingredients for the frosting. Beat until fluffy and well combined.
½ cup butter, 1 teaspoon vanilla extract, 4 cups powdered sugar, 4 to 6 tablespoons whole milk or heavy cream
Divide the frosting into different bowls for your desired colors. Stir in food coloring. I recommend starting with less then adding more until you get the desired color.

Notes
Any nutritional information is an estimate by online calculators. Please verify using your own data.*I recommend plain shortening and not butter flavored shortening.Storage:Store any leftover cookies in an airtight container. They will be good for up three days after making. If you live in a warm climate, you may want to store them in your refrigerator.Tips:
Be sure to chill the dough. Without chilling, the cookies may spread too much.
Let your cookies cool completely before frosting them.
