Our neighbor returned a plate of ours with sugar cookies on it (her rule is never return a plate empty...that's a nice rule don't you think?) Anyway, I think they were heavenly, melt in your mouth, fluffy sugar cookies. They were so good that I had to save Greg two to taste even though he was out of town. It was very hard to do with them staring at me on the counter for a day and a half but I resisted ;) Here is the recipe:
1 c. white granulated sugar
1 c. powdered sugar
1 c. oil (anything but peanut - I use canola)
1 c. butter, softened
1 t. salt
1 t. vanilla
Beat and mix above ingredients together using mixer. Then add 1 t. baking soda and 4 c. flour (all-purpose is fine; I have used half all purpose and half cake flour on occasion). Drop by rounded spoonfuls into granulated sugar to coat (it's normal for the dough to be very soft, almost like marshmallow creme). Transfer to ungreased baking sheet and flatten slightly (they expand minimally so you can put them rather close together).
Bake 8-10 minutes at 375 degrees until cookies look set. Cool on wire rack. Frost with vanilla cake frosting.
