If I were you, I would just use a regular chocolate chip cookie recipe and make the cookies large. If you want the coffee flavor, just add coffee powder (not granules!)to the recipe, or use coffee-extract instead of the vanilla extract.
Here is my sister’s chocolate chip cookie recipe, it is yum! It makes about 70 small cookies, so depending on how many cookies you need you might have to multiply the recipe:
1 cup margarine
3/4 cup dark brown sugar
3/4 cup white sugar
2 eggs
1 tsp. salt
1 tsp. vanilla extract
1 tsp. baking soda
2 1/4 cups flour
1 package chocolate chips
Cream the margarine and sugars. Add the eggs one at a time and beat, then add the vanilla extract and beat. Add salt, baking soda, flour and mix, then add chocolate chips.
These need 8-10 minutes at 350 degrees for smaller cookies, so if you are making huge ones they probably need 12-15. I am paranoid about baking times, so I would probably still check them after 10. Make sure not to crowd them on the cookie sheet because they spread.
If you are in EY, so 1 cup of margarine = 1 Israeli package. Increase the flour to 2 1/2 cups, too, because American flour is heavier. 350F = 180C.
Hatzlachah and a freilichen Purim!
