Double Chocolate Chip Cookies

I find I make cookies a lot! Which is great and all, but trying to get new recipes all the time is hard work! These cookies were very good, however, I found they were quite flat. I think it was because I used butter instead of margarine like I usually do. but, try them out and you be the judge! I found this recipe on food.com and it made a ton of cookies, I even froze some of the batter. Very easy to make. The recipe is below:

Double Chocolate Chip Cookies
1 1/4 cups of margarine
2 cups of sugar
2 eggs
2 teaspoons of vanilla
2 cups of flours
3/4 cups of cocoa
1 teaspoon of baking soda
1/2 teaspoon of salt
2 cups of chocolate chips

Cream together margarine and sugar. Add eggs and vanilla. Combine with cocoa, baking soda and salt. Add flour and mix thoroughly. Fold in chocolate chips. Bake at 350° for 7-9 minutes.
