Combine the frozen bananas and almondmilk in your blender. Blend until creamy, but not totally smooth. (My Vitamix has a wand that helps to push down the bananas while blending, but if you don’t have a wand you might need to pause once or twice to scrape down the sides.)
Add Simple Mills cookies, cacao nibs, and vanilla extract and pulse until the cookies are broken up to your liking. (I usually crush them slightly by hand as I add them in, and then it only takes another ten seconds or so to blend.)
Scoop straight out of the blender and eat immediately for a soft-serve texture, or transfer into a freezer-safe container, freeze and serve as a harder more scoop-able ice cream a few hours later.
