First, gather all the ingredients before starting the recipe. I usually measure the protein powder, yogurt, and almond milk in advance so the blending process becomes quicker. Cutting the banana into smaller pieces also helps it blend smoothly.
Place the banana, vanilla protein powder, Greek yogurt, cinnamon, almond milk, and ice into a blender. I prefer adding the liquid ingredients first because it helps the blender mix everything more easily and prevents clumping.
Start blending at a low speed and gradually increase to high. Blend for about 30–45 seconds until the mixture becomes creamy and completely smooth with no chunks left.
If the shake feels too thick, add a little more almond milk or water and blend again. If you prefer a thicker smoothie, simply add a few extra ice cubes and blend briefly.
Once the shake reaches your preferred texture, pour it into a tall glass. I like sprinkling a small pinch of cinnamon on top to give it a beautiful finishing touch before serving.
