How to Make Twisted Sugar Oatmeal Cookies:
Preheat the oven to 350°F and line a cookie sheet with parchment paper or a silicone baking mat.
Cream together the butter, brown sugar, and granulated sugar until light and fluffy.
Add the egg and canola oil, mixing until just combined.
Mix in the flour, rolled oats, cornstarch, baking soda, and salt until a soft dough forms.
Stir in the chocolate chips until evenly distributed.
Portion out the cookie dough into 1/3 cup portions, roll into balls, and flatten slightly before baking.
Bake at 350°F for 11-13 minutes or until the edges start to turn golden brown.
Allow the cookies to cool on the pan before enjoying.
