Place bananas in your Thermomix bowl and mash for 4 seconds on speed 4.
Add remaining ingredients (except cacao wafers!) and mix for 8 seconds on speed 4.
Let cake mix rest for a few minutes to thicken. Meanwhile, use a sharp knife to quarter your cacao wafers.
Add cacao wafers to Thermomix bowl and mix through on reverse, speed 3 for 5 seconds.
Scoop mix into a lined cupcake tray, filling all the way to the top as they won't rise all that much. Bake for 45-50 minutes, or until cooked through (skewer inserted in middle of cupcake comes out clean) and lightly golden on top.
Allow to cool in muffin tin for 10 minutes before removing to a cake rack and cooling completely.
