Protein Shake (Chocolate Banana)

Method

1. 1Freeze the banana ahead of time. Peel ripe bananas and freeze them whole in a bag or container. A frozen banana makes the shake cold and thick without ice — ice chills but also dilutes. Frozen banana does both jobs without the watery finish. Keep a bag of frozen bananas in the freezer at all times if you make shakes regularly. Ripe bananas with brown spots freeze best and taste sweetest — they're sweeter than fresh yellow bananas once frozen.
2. 2Add ingredients to the blender in the right order. Pour the milk in first so the blades have liquid to work with before they hit the frozen banana. Then add the oats, protein powder, cocoa powder, and salt. Add the peanut butter last — it tends to stick to the sides if added first. Place the frozen banana on top. This layering order means the blender starts easily instead of struggling against a solid block of frozen fruit.
3. 3Blend on high for 45 to 60 seconds. A proper protein shake needs more blending time than you think — 15 seconds leaves chunks of oat and streaks of protein powder. Blend until completely smooth and the texture looks uniform throughout. If the blender stalls, stop, use a spatula to push everything toward the blades, and restart. The shake should pour smoothly and look thick, not watery. Add a splash more milk if it's too thick to pour.
4. 4Taste and adjust before serving. Try the shake now: if it's too sweet, add a pinch more cocoa or salt; if it's not sweet enough, add half a teaspoon of honey or a few drops of vanilla extract; if the protein powder flavor is too strong, add more frozen banana next time. These adjustments take ten seconds and make the difference between a shake you look forward to and one you force down. Drink within 15 minutes of blending — the texture degrades as the banana warms.
5. 5Serve and clean up immediately. Protein shakes leave a residue that is significantly harder to remove once it dries. Rinse the blender immediately with warm water and a drop of dish soap, blend briefly, and rinse again. Thirty seconds of cleanup now saves five minutes of scrubbing later. For the shake itself: drink straight from a tall glass. The shake holds for up to 6 hours in the fridge in a sealed bottle, but the texture is best fresh.
