Thick, chewy, and soft, these Oatmeal Chocolate Chip Cookies are bursting with ooey-gooey chocolate goodness that everyone will love. Easy recipe, ready in just 30 minutes!
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. Set aside.
In a large bowl, use an electric mixer to beat the butter, brown sugar, and granulated sugar on medium-high speed until smooth and well combined, about 1 to 2 minutes. Beat in the eggs and vanilla. On low speed, gradually add the flour mixture and beat until just combined. Stir in the oats and chocolate chips.
Using a large spring-loaded scoop, drop 3-tablespoon sized balls of dough onto prepared baking sheets. Flatten slightly with the bottom of a measuring cup.
Bake for about 14 to 15 minutes, or until the edges are slightly browned, rotating baking sheets halfway through. If you prefer a slightly softer cookie, bake about 12-13 minutes, or until the edges are slightly brown but the middle still looks underdone (will firm up while cooling). Let the cookies cool on baking sheets for 5 minutes before removing to wire racks to cool completely.
