Hi all. I have a not far from standard chocolate chip cookie recipe that
I'm trying to get just right.

1/2 cup softened butter
1/2 cup shortening
1/2 cup brown sugar
2 eggs
2 cups chocolate chunks
2 1/3 cups flour
1 tsp salt
1 tsp baking soda
2 tsp vanilla

I'm pretty sure I can get it to spread less replacing the butter with
shortening, but I like cookie better with the butter in it. How can I get
the cookie to not spread so much while cooking? Thanks.
