Start by pouring 1 cup of unsweetened vanilla cashew milk (or your preferred milk) into the bottom of your blender. This helps everything blend more smoothly.
Drop in your frozen banana slices and 1–2 cups of ice, depending on how thick you want your smoothie. I usually go with 2 cups for a milkshake-like consistency.
Scoop in 1 tablespoon of unsweetened cocoa powder and 1–2 tablespoons of peanut butter. These are the ingredients that give this smoothie its rich, chocolatey flavor.
Add one scoop of your favorite chocolate protein powder. Then, sprinkle in a small pinch of salt—it enhances the chocolate and balances the sweetness of the banana.
Secure the lid, then blend on high for 30–60 seconds, or until completely smooth and creamy. Scrape down the sides with a spatula if needed, then give it one final pulse.
Pour the smoothie into a tall glass or mason jar, top with a few chocolate chips (if you're feeling fancy), and enjoy right away!
