Why it works
Peanut butter and banana have been a pairing longer than most institutions have been a department. The banana brings sweetness and body, the peanut butter brings richness and protein, and Greek yogurt adds tang so the whole thing does not taste like dessert. The soaked oats blend in smoothly and turn a snack-sized drink into a meal: about 730 calories, 30g protein and 16g fibre per serving.
Getting the texture right
Peanut butter thickens a smoothie more than you would expect. Add milk a little at a time while blending until it pours the way you like it. A frozen banana makes it colder and thicker, so you will need even more milk.
Swaps
Crunchy peanut butter works, but blend longer. Almond butter makes a milder version. Maple syrup can replace honey, or leave the sweetener out if the banana is very ripe. Need the base? Soak rolled oats, milk, chia seeds and a few almonds overnight.
Serving ideas
Pour it into a bowl and top with banana slices and crushed peanuts for a spoonable version.
