Preheat oven to 375°

Beat butter & shortening with electric mixer on med/med-high 30 seconds

Add brown & white sugar, baking soda, baking powder, Cinnamon and salt and beat until combined, scraping sides & bottom of bowl often.

Beat in eggs and vanilla until combined

Beat in flour gradually - 1/2 cup at a time

Stir in chocolate chips

Cover cookie sheets in parchment paper and drop by spoon 2" apart (Teaspoon for kid size portions, rounded tablespoon for adult)

Bake 7-11 min (edges are light brown)

Let cool on cookie sheets 1-2 min then remove to cool further on cooling racks.

Note - keep your dough as cold as possible. It helps keep your cookies from being flat! I like to place cookie sheets in fridge or freezer for a few min before adding new dough!
*Note - also parchment paper is reusable! I get 3-5 uses from each piece!
