Break the frozen açaí up a little by slapping the sealed packets on the counter or hitting them with a mallet.

Blend the açaí with half of the banana and the coconut milk (or water) until it's the consistency of a thick smoothie.

Slice the remaining half banana.

Arrange the banana slices, the berries, the AtheenOats What the Nut Granola, and the coconut flakes on top of the açaí.
