One of my favorite treats is a Pain Au Chocolate. It's like a croissant filled with a semi sweet chocolate. It is wonderful. Here is an easy Nutella recipe that gets you close to a Pain Au Chocolate without having to go to Paris or a good bakery.
Roll out a tube of Pillsbury of crescent dough. Separate each of the triangles and lay them flat. Put a tsp of Nutella near the wide side and roll it up as you normally would. Pinch the ends closed. Use a pastry brush, to brush lightly with a melted butter.
Place the crescent rolls on a baking sheet. Bake in a preheated 375 degree oven for 15 minutes or until the croissants are golden brown. Remove from the oven, and let cool slightly. The Nutella will be extremely hot inside the roll, so unless you want a molten lava experience in your mouth, wait a few minutes.
