Nutella^® Mini tarts

Put the flour and baking powder into a pile on the pastry board. Add the softened butter in pieces in the middle. Mix quickly to make a pile of "crumbs" then add to the crumbs the sugar, yolk and egg, grated lemon zest and a pinch of salt. Mix everything together quickly, forming a ball. Wrap it in a cloth and put it in the fridge to rest for 30 minutes.

Using a rolling pin, roll out the dough to a thickness of 5 mm and cut out circles slightly larger than the individual tins that you are going to use.

Put the dough into the greased and floured tins. Bake in a pre-heated oven at 180°C for 8-10 minutes. Afterwards, remove the tarts from the cases and let them cool. Fill the tarts with Nutella^® and serve.
