Fold in blueberries 6 ounces of blueberries, then scoop out 15 equally sized balls of dough (about 3 tablespoons). You will want to place them about 1 ½ inches apart as they will spread.
Optionally, roll balls in about ¼ cup of granulated sugar, then lightly add the remaining blueberries to the top.
Bake for 15 minutes or until they start to get a golden-brown color along the edges of the cookies (note: if you like your cookies a bit stiffer bake for another 1-2 minutes).
