Preheat the oven to 350℉/176℃. Line a baking tray with parchment paper and set aside. Melt the butter and allow it to cool as you prep the rest of the ingredients.
3/4 cups unsalted butter
In a bowl, add the flour, oats, baking soda, baking powder, salt, and cinnamon. Stir to combine and set aside.
1 1/2 cups all-purpose flour, 2 cups rolled oats, 1 tsp cinnamon, 1 tsp baking soda, 1/2 tsp baking powder, 1/4 tsp salt
In a large bowl, add the butter, white sugar, and brown sugar. Whisk together to combine (about 2 minutes).
3/4 cups dark brown sugar, 1/4 cups white sugar, 3/4 cups unsalted butter
Add in the eggs and vanilla. Continue whisking for a minute or so until well combined.
2 large eggs, 1 tbsp vanilla
Add in the dry ingredients. With a spatula, gently fold until a soft cookie dough forms. Sprinkle in the chocolate chips and mix a few more times to incorporate them. Don't over-mix!
3/4 cups semi-sweet chocolate chips
Scoop the cookies 6 at a time on the baking tray, spacing them evenly apart from one another. Place extra chips on top.
Bake for 13-15 minutes. For gooey-er middles, bake for 13 minutes. For crispier edges, bake for 15 minutes.
Allow to cool, and enjoy! These cookies are so delicious!
