Combine your frozen yogurt, frozen bananas, protein powder, non-frozen yogurt, vanilla extract and your preferred milk into a blender and blend until smooth. If this is difficult to blend, simply add a little more milk, 1 tbsp at a time, to avoid it getting too wet.

Scoop out half of the blended mixture and set aside, then add cocoa powder into the blender and mix well. Add more cocoa powder if you prefer.

Pour the chocolate yogurt mixture into a glass then add the vanilla-banana yogurt on top.

To serve, dust some cocoa powder on top, garnish with a few small dark chocolate pieces (both are optional!)

Serve immediately and enjoy!
