This is, by far, the best (and easiest) snickerdoodle recipe I've ever come across. I got the recipe from my friend, Barb ( of Tiny Bubbles), and can't believe how quickly they disappeared over the weekend!
1 stick butter
1 1/2 c sugar
1 tsp vanilla
1 1/2 c flour
2 tsp cream of tartar
1 tsp baking soda
1/2 tsp salt
Spread batter on greased 9x12 pan
Sprinkle a mix of sugar & cinnamon (2 tsp each)
Bake at 400 degrees (10-15 minutes)
Watch, in amazement, at how fast they disappear!
