Updated Chocolate Chip Cookies

1. Preheat the oven to 350ºF and line 2 baking sheets with parchment paper.
2. In a medium size bowl, mix together the flour, oats, flaxseed, baking soda, salt, and cinnamon. Set aside.
3. In an electric mixer fitted with a paddle attachment, on medium high-speed, cream together the butter and sugars until light and fluffy, about 4 minutes. Beat in the eggs one at a time, incorporating each before adding in the next. Beat in the vanilla. Reduce speed to low and add in the flour mixture and beat until just combined. Stir in the chocolate chips.
4. Drop large tablespoonfuls of dough onto the baking sheets, about 2 inches apart. Bake until golden brown, 10-12 minutes. Let the cookies cool on the baking sheets for 3 minutes and then transfer to a wire rack to cool completely.
