Add all ingredients through the peanut butter to your blender. Add about half the ice that you will be using. Blend on high until combined completely.
Add cocoa nibs and remaining ice. Blend until just combined so you still have an icy treat with the cocoa nibs intact.
If you’re using a Blendtec*, there is a smoothie button you can just push and it will do all the work for you while you clean up.
