Sugar Cookies
Makes about 30 cookies

1/2 cup sugar
1/2 cup brown sugar
1/2 cup butter
1/2 cup vegetable oil
1 egg
1 tsp vanilla
2 cups flour
1/2 tsp baking soda
1/2 tsp salt
1/2 tsp cream of tartar

Preheat oven to 350 F/175 C.
Cream together the sugars, butter, and oil. Add the eggs and vanilla. Stir in the flour, baking soda, salt, and cream of tartar.
Roll the dough into walnut-sized balls and cook on an ungreased cookie sheet. Bake for about 10 minutes, or until golden brown.

Got home from school, lack of homework, made cookies. Also made some of dinner (we have people over), but I'll update that later. Modified from Allrecipes.
