Add liquids first. Pour the milk into your blender. This helps the blades spin smoothly and prevents clumping.
Layer the powders. Add protein powder and cocoa powder.
This ensures they blend evenly without sticking to the sides.
Pack in the greens. Add the spinach on top. If using frozen spinach, break it into smaller chunks.
Sweeten and thicken. Add the banana and nut or seed butter. Frozen banana makes the smoothie extra creamy.
Customize. Add any optional ingredients you like, such as vanilla, cinnamon, or seeds.
Blend until smooth. Start low, then increase to high for 30–60 seconds, scraping the sides if needed.
Add ice and blend again to reach your preferred thickness.
Taste and adjust. If it’s too thick, splash in more milk. If you want it sweeter, add a touch of maple syrup or honey and blend briefly.
Serve immediately. Pour into a chilled glass or take it to go in a lidded cup.
