Never Flat Chocolate Chip Cookies

I'm always on the lookout for the perfect chocolate chip cookie recipe--one that makes cookies that are chewy and soft in the middle and slightly crisp on the outside, and that don't get flat or seem too dense. I found this recipe when organizing my cookbooks/recipes this weekend, and decided to try it. I think my search for the perfect chocolate chip cookie may be over--these cookies were SO yummy!

*Note: this makes a large batch, so feel free to half it if you want a smaller/normal sized batch. I rolled the extra dough into balls and froze them for later use.

Combine the following until creamy:
1 1/2 cup sugar
3 eggs
1 lb. (4 sticks) real butter (softened)
2 cups brown sugar
2 Tbsp. vanilla

Combine the following and then mix with the creamy mixture:
6 cups flour
1 1/2 tsp. baking soda
1 tsp. salt
2 heaping cups (1 pkg.) chocolate chips

Bake at 350 for 9-10 minutes.
