In one bowl, mix the flour, the baking powder, the dry yeast and the lemon skin. In another bowl, add the butter melted and the 4 eggs one bye one, already beat it ups, after add the greek yogurt and the vainilla extract. Mix everything until you get a very creamy mixture.
Then, add by tablespoons the flour mixture that we have previously made and with wrapping movements we will integrate it until we get a creamy mass and a little thick at the same time. Add the chocolate chips and let the mass rest for 30 min in the fridge covered with a paper. After the 30 min put the mixture in the molds. Bake it for 20-15 min at 200C in the oven (previously heat it at 220)
Let the Cupcakes cool a bit and enjoy them.
