Mix 60ml milk with the cornstarch (make sure there are no lumps) and set aside.
Mash the banana.
Scrape the pulp out of the vanilla pod and put it in a saucepan with the chocolate and milk (the whole pod can also be placed in the saucepan and cooked with it, then the vanilla flavor becomes even more intense. Before the cornstarch comes in, simply remove it)
Bring everything to the boil briefly, stirring constantly, then remove the saucepan from the stove and slowly add the starch while stirring. Bring to the boil again while stirring and simmer briefly until the pudding thickens. Then add the banana mixture and puree.
Cut the puff pastry into 12 equal-sized squares and press into a muffin tin. Then add a tablespoon of pudding to the puff pastry baskets. Place half a strawberry in the middle of each basket.
Bake everything at 200 degrees on the middle rack for about 30 minutes.
Then distribute the rest of the pudding in the basket and let everything cool down. Before serving, decorate with a strawberry and add whipped cream if necessary
