Before You Begin
Preheat and prepare your cookware as needed. Cooking times and results may vary depending on your oven and baking equipment. Use caution when handling hot baking sheets and cookies.
Mix Dry Ingredients
Whisk flour, cinnamon, baking soda, and salt in a bowl until evenly combined.
Cream Butter and Sugars
Beat butter, brown sugar, and granulated sugar for about 3 minutes, or until creamy.
Add Eggs and Flavorings
Mix in eggs one at a time until blended. Add molasses and vanilla and mix until smooth.
Combine Mixtures
Mix dry ingredients into wet ingredients on low speed until just combined.
Add Oats and Chocolate
Fold in oats and chocolate chips until evenly distributed.
Chill Dough
Cover and refrigerate for at least 45 minutes so the dough firms slightly and bakes evenly.
Bake
Preheat oven to 350°F (177°C). Scoop dough into 2-tablespoon portions and place 3 inches apart on lined baking sheets.
Bake 13–14 minutes, or until edges are lightly browned and centers appear set.
Cool
Let cookies rest on baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
