1 frozen large banana, as ripe as possible
cacao nibs (or chocolate chips)
2 drops pure peppermint extract
2/3 cup milk of choice (For a super-rich shake, try full-fat canned coconut milk. Also, use more or less, depending on desired thickness.)
frozen spinach (I used about 1/4 cup) *If you can’t get on board with the greens-in-smoothies thing, you can opt for green food coloring (or just drink a white mint shake).
If, like me, you prefer smoothies in a bowl, add a pinch of xantham and guar gums to make pudding (or just reduce milk)
Of course, you can always add cocoa powder too
