Combine the almond milk, coffee, frozen banana, vanilla Greek yogurt and cocoa powder in a blender.
Blend for 1 minute, or until combined and smooth.
Smoothie should be a thick, frosty consistency. If not, add 4-5 ice cubes and blend again to thicken the smoothie.
Serve immediately.
Notes
To make double strength coffee, simply double the amount of coffee grounds that you use to brew your coffee. Do not make any adjustments to the amount of water used.
