Snowflake Sugar Cookies

1 cup granulated sugar

1 cup powdered sugar

1 cup butter

1 cup vegetable oil

2 eggs

1 teaspoon good quality vanilla

1 teaspoon salt

1 teaspoon cream of tartar

1 teaspoon baking soda

4-1/4 cups flour

Extra sugar for pressing cookies (colored sugar is an option)

Preheat oven to 375 degrees F.

Cream together the granulated sugar, powdered sugar, butter, and cooking oil. Beat in eggs and vanilla.

Add the next 4 dry ingredients and mix to incorporate.  Roll dough into small balls about the size of a quarter. Press balls flat using a heavy crystal vase dipped in sugar leaving an imprint and sugar on the top. Bake in a 375 degree oven for 8-10 minutes until the edges just start to slightly color. Do not bake too long. Cool on the baking sheet briefly then transfer to cooling surface.
