If you've frozen the bananas in advance, leave them at room temperature for about 10 minutes to soften slightly. If they aren't frozen, just use ripe bananas.
In a blender or food processor, blend together: • Bananas • Protein shake powder • Milk or milk alternative until smooth and creamy.
At the end, gently mix in extras like pistachios or chocolate chips.
Pour into a container or airtight tub and freeze for 2-3 hours. (If you stir it once in the middle, it gets even smoother!)
Let it sit at room temperature for about 5 minutes before serving so it's easy to scoop. Sprinkle some nuts on top to finish off with a café-style vibe!
