Cover your bowl and let chill in the fridge atleast 1 hour but preferably 24-36.
Once chilled preheat oven to 350. Lightly grease your cookie sheet and place 1Tbls. of dough about 2 inches apart. Bake 13-15 minutes.
(Rotate cookie sheet half way through baking)
Let cookies cool completely and Enjoy!
Side Note: Cookie dough may be frozen. No need to thaw. You can take them straight from the freezer to the oven with no adjusted baking time. Place your dough on a cookie sheet (1Tbls per cookie) place your sheet in the freezer until the dough is frozen solid. Remove from freezer and place cookie dough in a freezer bag. So simple if you want to have cookie dough on hand for guests.
