Notes from the Test Kitchen:
These tasty cookies are a great way to tame your sweet tooth! I sprinkled raw sugar on the top and just loved the slight crunch it gave to these otherwise scrumptiously soft cookies.
1Preheat oven to 375 degrees, Combine butter (let butter get very soft for best results), sugars (sift sugars together), and oil in a large mixer bowl using medium speed. Beat in eggs and vanilla.
2Sift flour, baking soda, and cream of tartar together; gradually beat into creamed mixture using low speed. Mix well.
3Shape teaspoons of dough into balls (dough will be soft). Place 2 inches apart onto ungreased cookie sheets. Flatten slightly with tines of fork, which have been dipped in sugar. (You can sprinkle a little more sugar on top if desired.)
4Bake at 375 for 10 to 12 minutes or until lightly browned. Remove cookies; cool on racks.
5Store in a covered container.
Note: The original recipe calls for margarine and vanilla extract. It also calls for all-purpose flour. I use self-rising flour. I have found the taste is better using unsalted butter and real vanilla.
