Right before rolling out the dough, prepare the filling. In a small bowl combine the melted butter, brown sugar, cinnamon, and maple syrup and stir until combined. Set aside.
7 Pour out the dough onto a lightly floured surface and roll into a 12×16 inch long rectangle. Spread the filling in the center of the dough, leaving 1 inch off of the sides.
8 From the long side, roll the dough into a log and slice it into 1” slices. You can cut off the ends and discard them if they are too small or have no filling inside. Place the pieces with the cut side up in a 9×13” pan and leave them again to rest for 30 mins with a covered teal towel in a warm spot.
9 Preheat the oven to 350°F and bake the buns for 20-25 mins until puffy and golden brown.
10 While the buns are baking, make the maple glaze. In a small bowl combine the confectioners sugar, maple syrup, and milk. Drizzle all over the buns when they come out of the oven and serve.
