Kick the tires and light the fires to 350 degrees.
Mix the oats, flour and baking soda together in a small bowl and set aside.
Take the sugar, butter, and peanut butter and put in the bowl of an electric mixer and put on your paddle attachment.
Whip until the mixture is pale and fluffy, about 5 minutes, then add in the eggs and vanilla then mix until combined.
Put your mixer on the lowest setting, then add the oat mixture and mix until just combined, then it's time for the peanuts and chocolate chips! The peanuts make this so, so good! With the crunch and the salt and the complete unexpectedness of it.
Drop by large tablespoon onto a parchment lined sheet, I fit only 8 per cookie sheet.
Bake cookies, rotating sheets halfway through, until golden brown , about 9 -11 minutes.
You want to let them be slightly underbaked and then cool them on the sheets completely. If you don't cool them on the sheets they WILL fall apart! You need them to be soft to compliment the hard crunch of peanuts and in order for them to set, they have to cool completely.
