In a large bowl, combine water, yeast and honey. Mix with a spoon, then let sit until foamy, about 10 minutes. Add in the 1 1/2 cups whole wheat flour, all-purpose flour, cinnamon, salt and olive oil, stirring with a spoon until the dough comes together but is still sticky.
Using your hands, on a floured surface, form the dough into a ball and work the additional 1/2 cup flour into the dough if needed. All of the mixing and kneading can also be done in a stand mixer with the dough hook attachment.
Working on one side of the dough or with one dough round, add two pieces of chocolate. Flatten one marshmallow and place it on top of the chocolate. If desired add another two pieces of chocolate (I did). Now either take the top half of the dough and fold it over the filling or add the top round of dough.
Crimp the edges of the dough to seal. At this point, the s'mores can be placed on a floured cookies sheet, covered and stored in the fridge overnight or until ready to cook.Preheat the grill to medium high heat or the oven to 375 degrees F.
