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. To prevent the tarts from swelling up too much, prick the dough a few times with the prongs of a fork. 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.
Tarts are the small but great classics of pastry baking. Add Nutella® and they get that extra touch of excitement to make their shortcrust pastry even more irresistible. Our Nutella® tarts recipe is perfect for adding some creativity to your parties!
