Put the berries on top of the dough we baked before and spread them out evenly.
Sprinkle the crumble on top, also trying to make it as even as possible.
Pop it in an oven (still at 180C) for 20-30min or until the crumble is golden.
Let it cool down to room temperature and then put it in the fridge for 15min just to make sure it won't get ruined as you cut the bars.
Unmould by gently lifting the baking paper. From this you can cut as many bars as you like, I had 8.
