Lemoine Family Tea Cakes

I'm pretty sure this was my Granny Grace's recipe, correct me if I'm wrong, Mom. This is probably Ray's favorite cookie.

Cream together:
1/2 lb butter (2 sticks)
2 cups sugar
3 eggs
Large spoon vanilla-1 tsp plus 1/2

Seperate bowl:
5 c. flour
Tsp baking powder

Combine ingredients, and refrigerate 1 hour. Roll to 1/4 inch and cut with small cup or biscuit cutter. Bake at 350 degrees for 10-12 minutes.
