In your blender, combine all the ingredients—brewed coffee, frozen banana, peanut butter, vanilla extract, cocoa powder and milk.
Blend and pulse until completely smooth.
I used some chocolate syrup to garnish the inside of my glass before pouring the smoothie in. This is completely not necessary, but a fun final touch!
Serve immediately.
Notes
If you want the coffee flavor to be the top flavor, consider subbing peanut butter for almond butter—it’s more neutral in taste with the same hearty qualities.
If you don’t have brewed coffee, you can substitute it with equal parts cold brew. The caffeine in brewed coffee and cold brew are pretty much the same.
If you are limiting caffeine, consider subbing for decaf or half-caf coffee.
