Who cares! This decadent, deviant version of banana bread will stop you worrying about petty health concerns. It's sinfully full of chocolate with a caramelised banana crust. It's great. You'd want to marry this recipe.
Preheat the oven to 180°C.
Whisk together the flour, cocoa powder, baking powder and salt. Chuck in the chopped chocolate.
Using an electric hand whisk or a stand mixer, whisk together the butter and caster sugar, until the mixture has lightened and is fluffy. Add the eggs, one at a time, keeping whisking between each addition.
Add the sour cream, bananas and vanilla essence.
Now, line a 20cm baking tin and scatter the sugar on the bottom. Carefully slice the bananas lengthways and arrange them in a pattern on the base of the tin, cut side down.
Bake for 30 minutes, then cover with foil for the final 30 minutes.
