Step 1

Preheat oven to 375° F. In a large mixing bowl, cream together the butter, brown sugar, and sugar until light and fluffy with a mixer.

Step 2

Add the egg and vanilla and mix well.

Step 3

Combine the baking soda, salt, and flour in a bowl. Add the flour mixture to wet ingredients and mix just until combined.

Step 4

With a food processor or mini food chopper, pulse ¾ cup oats until the oats have been broken up and begin to appear as a coarse flour. The other ¼ cup oats should be left as-is. Add all of the oats and 1 cup chocolate chips to the dough mix until combined. The dough will be thick.

Step 5

Scoop cookie dough onto a cookie sheet lined with parchment paper. Bake for approximately 8-10 minutes for small cookies or 12-14 minutes for large cookies. The cookies should still be very soft. Err on the side of underbaking these cookies rather than overbaking.
