Prep your base: Add the frozen banana, cocoa or cacao, milk, yogurt, nut or seed butter, sweetener (if using), vanilla, and a pinch of salt to your blender.
Blend low and slow: Start on low speed and work up to high.
Scrape down the sides if needed. If it’s too thick to blend, add milk 1 tablespoon at a time until the blades catch.
Adjust texture: For a bowl you can eat with a spoon, aim for a soft-serve consistency. Add a few ice cubes for extra thickness or a splash more milk for smoothness.
Taste and tweak: If you want it sweeter, add an extra date or a little maple syrup.
If you want a stronger chocolate flavor, add another teaspoon of cocoa and blend again.
Serve and top: Pour into a bowl and add your favorite toppings. Go for a mix of creamy, crunchy, and fresh so every bite is satisfying.
