Instructions
Preheat oven to 350 degrees F. Beat butter and sugars until smooth. Add vanilla and egg and mix until combined.
In a separate bowl, stir together flour, soda, salt, baking soda, baking powder and cream of tartar. Add flour mixture to butter mixture and stir until incorporated.
Divide the dough into about 12 equal sections (you can make them smaller if you want) and shape into balls. Place dough balls 3 inches apart (6 per cookie sheet) on parchment lined or non-stick cookie sheet and flatten tops slightly.
You don't want to flatten it too much, you just don't want it to look like a ball. Bake for about 15 minutes or until brown around the edges. Cool slightly on cookie sheet for about 5 minutes, then transfer to a rack to set: remove from baking sheet. Cool on wire rack. Makes about 12 big cookies.
