Firstly, mash the bananas with a fork in a bowl. Add the flour, white sugar, instant coffee, melted vegan butter substitute, espresso, cinnamon, baking powder, and a pinch of salt, and combine. You can already preheat the oven to 180° C (360F°).

Add finely chopped dark chocolate and half of your baking chocolate. Check for seasoning. The dough should have a rather wet consistency. 

Mix the dough by hand just until all ingredients are combined. 

Add the dough to a greased loaf pan and sprinkle the banana bread with your remaining baking chocolate and cane sugar.

Bake the banana bread at 180° C (360° F) for 50 mins. Let the banana bread sit for 15 minutes after baking before digging in.
