Line 2 baking sheets with parchment and set aside.
In medium sized bowl, add in the peanut butter an sugar. Mix on medium high speed until well blended, about 30-60 seconds. If you are mixing by hand, you might need to mix a little longer. Add in eggs and vanilla and mix again, this time only to combine. It should take no longer than 10 seconds. Next is oats and baking soda. Mix again to combine. Be sure this is mixed well for even distribution of the baking soda. Last up is your chocolate chips. These only need to be mixed until they are combined as well.
Now, scoop your cookies onto baking sheet. They spread, but not too much. I did 12 per sheet, a 3 cookie x 4 cookie grid.
Place cookies in fridge to chill for about 20 minutes. While they are chilling, preheat oven to 350 degrees.
Once they have chilled, remove from fridge and place in oven.
Bake until they are lightly browned around the edges. Mine took right about 8 minutes. This will depend on the actual heat of you oven, thickness of pan, thickness of cookies, etc.
With these flourless cookies, it is best to allow them to cool for a few minutes before trying to remove from the pan, as they don't have the structure cookies with flour have. So, allow to cool for a fer minutes, then move to a cooling rack.
These are delicious warm with a cold glass of milk or however you take them! Everyone will be so surprised this a flour free cookie, it does not taste or have the texture of one! They are so good!
Now, sit back and enjoy. You deserve it!
