Snickerdoodle Bars

1/2 c butter

1 c sugar
1 egg
1 t vanilla extract
1 1/2 c flour
1/2 t baking soda

2 T sugar
1/2 t cinnamon

Preheat oven to 350 degrees. In a large mixer bowl beat butter and sugar until fluffy. Add egg and vanilla and continue to beat until combined. Add flour and baking soda and combine. Press into a greased 8 x 11 pan. Combine sugar with cinnamon and sprinkle over dough. Bake for about 20 minutes. (18 minutes was perfect. A toothpick will come out clean but they will seem gooey. As they cool, they will set.)
