To make this shake, you'll start by whipping up a tiny batch of gluten-and refined-sugar-free peanut butter cookie dough. roll the dough into balls and chill for a quick handful of minutes. while the dough is chilling, you'll combine frozen bananas, nut milk, peanut butter, and vanilla in a food processor. give it a good pulse and then whirl the combination into a super thick shake. add half of the cookie dough to the food processor and pulse to chop and disperse bits throughout before scooping into a glass. as a final touch, you'll crumble the remaining cookie dough over top.
