Unique Cookie Recipe

A friend of mine told me about a recipe that his co-worker's wife was making that seemed to be a hit in his office.
My friend didn't even give the cookies a try, saying a perfectly good chocolate chip cookie was ruined by the addition of blueberries, like it was a sacrilege.
I was intrigued by the combination.
And they're tasty!

Milk Chocolate Chip Blueberry Cookies

1 cup softened butter
3/4 cup sugar
3/4 cup brown sugar (or another option is 3/4 cup of granulated sugar and 2 tsp of molasses)
2 eggs
1 teaspoon baking soda
1 teaspoon vanilla
1 teaspoon salt
2 1/4 cup flour
3/4 - 1 cup (or to your taste) blueberries (frozen or fresh, rinsed and patted dry)
Milk Chocolate chips, one 11.5 ounce bag (I thought that was a lot so initially used less, but the cookies really do need a lot of chips)

Cream butter with sugars.
Add eggs and beat until mixed well. Add vanilla.
In separate bowl mix together dry ingredients, then add to creamed mixture.
Mix well.
Mix in chocolate chips.
Carefully fold in blueberries.

Drop by spoonfuls onto ungreased baking sheet.
Bake 375 degrees for about 8 minutes, or to taste
Cool on baking sheet for one minute before moving to cooling rack.
Enjoy!
