Here we go with the Chocolate Pizza recipe:

CHOCOLATE BRIOCHE:
300g Strong Flour
15g Yeast, fresh
30g Sugar, white
6g Salt
3 Eggs, free range, large
135g Butter, unsalted, soft
20g Cocoa Powder

TOPPING:
2 Bananas, chopped
150g Pecans, chopped
150g Brown sugar, soft
100g Butter, unsalted, cut into cubes
15g cocoa powder
200ml Double cream
200g milk chocolate, droplets or small pieces
200g dark chocolate, droplets or small pieces

For the Brioche:
Mix all the ingredients except Butter in small machine with dough hook for 5 minutes on low speed
Add Butter, mix with higher speed until sides of bowl become clean and no dough sticks anymore
This can be done obviously by hand with initially a softer kneading and then with more force to get the same smooth, non sticking dough

For the Topping:
Roll out the dough to a round base, let this base now rest for 30 minutes covered loosely with Clingfilm by room temperature.
Sprinkle with cocoa, then sugar and then the butter
Top with the chopped bananas or slices if you prefer
Bake at 200 C for 15 minutes
Remove from oven, sprinkle with nuts and drizzle with double cream. Bake again for 5 minutes.
Sprinkle now with the chocolate droplets or pieces and just quickly melt them in the oven for another 2 min.
Serve still slightly warm
