The peanut-iest, chocolate-iest, oatmeal-iest cookie to satisfy even the Cookie Monster himself!
Combine peanut butter and roasted peanuts in a food processor. Blend until almost smooth.
Using a hand held or stand mixer, beat both sugars and the butter till fluffy, about 3 minutes. Add the peanut butter mixture and vanilla. Beat to blend.
Stir in chocolate chunks.
Preheat oven to 375F. Line two baking sheets with parchment. If both sheets won't fit on one rack in the middle of the oven, then arrange two rack in the upper and lower thirds of the oven.
Scoop out balls of the dough, about 2tbsp per ball. Space them 1" apart. Press down with your palm on each one. I usually get around 30 cookies.
Bake until golden and firming up, about 10-11 minutes. (rotate the sheets between the two racks and also turn 180 degrees halfway through the baking)
Remove and immediately sprinkle a little Maldon salt (or any finishing salt) on each cookie, especially any melted chocolate- it will hold onto the flakes the best.
Let them cool on the sheets for 2 minutes. Then transfer them to wire cooling rack to cool completely.
When I'm trying a recipe for the first time, I will often bake just one tray, and follow the instructions to a tee. Then I can monitor the results. If I'm happy then I can continue with the second tray, knowing that they will all turn out. If I feel I need adjust the cooking time, I can do so with the second tray.
If you would like to try this cookie using Einkorn or Emmer flours, use the required 3/4 cup, and reduce the butter by 1 tbsp.
