The Best Sugar Cookies You Ever Ate or Snitched

Oh MY!  If you have ever seen a plate of sugar cookies and was tempted to dive in, and then to your dismay they were too hard, too dense, or way too sweet, get ready to be smitten by these amazing sugar cookies. These cookies are great because they have butter & oil and cream of tarter. You must not skimp on these and they will turn out perfect every time. Folks take one bite and all seem to have the same response; "ooooooooohhhh, these are really good!"
Here you go:
Cream together: 1 c butter (no substitution), 2 eggs, 2 c sugar, 1 c oil ( not olive) canola, corn, or vegetable oil is fine, 2 tsp vanilla
In another bowl whisk dry ingredients; 5 cup flour, 2 tsp soda, 2 tsp cream of tartar
With mixer on low, blend flour mixture gradually into butter mixture until all blended. Dough will be moist and don't add extra flour. Scoop up with small or medium ice cream scoop so all cookies will be uniform in size. You may roll dough in colored sugar, mash down with the bottom of a glass and bake, or just bake plain at 350 F. for 12 minutes. Do not  over bake! Edges will be only slightly browned. Let cool on a wire rack until completely cooled, then if they are left plain you can frost with the frosting of your choice.  I like to make up a frosting that has 3 c powdered sugar, 4-8 ox cream cheese,  1 tsp. vanilla and heavy whipping cream until creamy, thick and smooth. It's a great for cupcakes and cookies of all types. Enjoy!
