Prep your banana. If you haven’t already, slice and freeze a ripe banana.
Frozen fruit makes the smoothie cold and creamy without needing much ice.
Add liquids first. Pour the milk into your blender. This helps the blades move smoothly and prevents clumps.
Layer the dry ingredients. Add cocoa powder, a pinch of salt, vanilla, optional oats, and protein powder if using. This disperses the powders evenly.
Add the creamy elements. Spoon in the nut butter, then add the frozen banana and optional sweetener (maple syrup or a pitted date).
Blend until smooth. Start low, then increase speed for 30–60 seconds.
If it’s too thick, splash in more milk. If it’s too thin, add ice or a bit more banana.
Taste and adjust. Want it sweeter? Add a touch more maple syrup.
Need more chocolate? Add 1 extra teaspoon cocoa.
Serve. Pour into a cold glass and finish with a sprinkle of mini chocolate chips or cacao nibs for that brownie bite feel.
