Peel and slice your bananas, then freeze them for at least 2 hours. Using frozen bananas gives the smoothie a thick, creamy texture that feels indulgent.
Add the frozen bananas, cocoa powder, milk, nut butter, honey, vanilla, and salt to your blender. Blend until smooth and creamy, scraping down the sides as needed.
If the smoothie is too thick, add a splash of milk and blend again. You want it thick enough to eat with a spoon but smooth enough to swirl.
Pour the smoothie into a bowl and add your favorite toppings like granola, berries, nuts, or seeds. I love a little extra cocoa powder on top for presentation.
