Try triple chocolate chips; use about 1/2 each of semi-sweet, dark and milk chocolate chips.
They are awesome!
Great way to use up chocolate candy bars leftover from summer S'mores.
In a large bowl, using a mixer, cream butter, shortening, sugars, eggs and vanilla.
Add dry ingredients and by hand, mix well.
Stir in chocolate chips and nuts, if using.
I like to refrigerate the dough for a couple of hours before baking. Not necessary though, cold dough just produces a firmer cookie, not so flat.
Drop by level tablespoons onto parchment lined cookie sheets. If you don’t use parchment, do not grease cookie sheets.
Bake at 350 degrees for 9-11 minutes.
Cool cookies on wire racks lined with paper towel to absorb the grease.
