I actually don't use chips... I prefer melts or chunks...

I made the yummiest choc chip recipe the other night and I added ovaltine to the dough... YUM!

Best Ever Chocolate Chip Cookies - Originally from Coconut & Lime Blog


Ingredients:
1 cup plus 6 tablespoons flour
1/2 teaspoon kosher salt
1/2 teaspoon baking soda
1/2 cup unsalted butter at room temperature
1/2 cup dark brown sugar
1/2 cup sugar
1 egg at room temperature
1 teaspoon vanilla
8 oz semisweet chips (I used Hershey's Special Dark chips)

Directions:
Preheat the oven to 350. Lightly spray one cookie sheet with spray oil. In a medium sized bowl combine flour, salt, and baking soda. In a large bowl, cream the butter and sugars until light and fluffy. Add the egg and vanilla and combine thoroughly. Gradually add the dry ingredients to the sweetened butter. Once combined, add chips and distribute evenly using the mixer on the lowest setting. Form cookies by dropping 1 teaspoon of dough on the sheet two inches apart. Smoosh them down a little then bake until light brown, about 12 minutes. Let cool if possible then serve with plenty of cold milk.

Yields: aprox. 2 dozen cookies, depending on size
I often mix it up and use a third white, a third dark and a third milk. But basically any chocolate, even lindt (whatever we have) gets used in choc chip cookies. And IMO brown sugar is a MUST in cookies... it just makes them chewy and delicious!
