In this recipe a store-bought puff pastry sheet was used instead of making your own croissant dough at home. Thats why its easy
1 Tbs milk
1 puff pastry sheet (thawed)
nutella (or chocolate chips)
Line two baking sheets with parchment paper and lightly flour your work surface. Lay the pastry sheet then lightly dust top with flour.
Roll out dough to a thickness of 5 mm to obtain a circle. Using a cutting wheel or knife, cut 12 triangles and put on the base of each triangle a teaspoon of nutella. Then Start to roll the dough base until the end, as shown.
Beat the egg and milk in a small bowl and brush the surface of your croissant with the egg-milk mixture. Cook them in the oven at 350 degrees F for 15-20 minutes.
