On a lightly floured surface, roll the dough in a big rectangle. Spread butter on all the dough and sprinkle with brown sugar. Distribute the diced apple on the brown sugar.
Beginning with one of the long sides, roll the dough by holding tight to form a roll. Cut the roll right across (on the width) in slices of about 1 inch thickness. Put down the slices in a big glass dish (Pyrex type) and sprinkle with maple syrup.
Cook in a preheated oven of 400 F for about 10 minutes.
