The night before, combine overnight oat ingredients in a jar, stir, and refrigerate overnight.
Add all smoothie bowl ingredients (except overnight oats, garnishes, and the extra banana half) to a high-speed blender. Blend on high until smooth, using the blender wand to push ingredients toward the blade and gradually adjusting liquid as needed.
Spoon the blended mixture into one half of a wide bowl and add the overnight oats to the other half.
Top with sliced banana, almonds, cashews, and hemp hearts. Sprinkle extra cacao nibs over everything.
Notes
If you're allergic to peanuts this would be delicious with other nut butters such as cashew, almond or sunflower!
