Butter the insides of a 10" tube pan with a removable bottom.
Roll the dough into a 8" x20" rectangle.
Spread the filling over the dough leaving a 1" border on one of the long sides.
Roll the dough up starting on the long side opposite the one with the border like you would for cinnamon rolls. Pinch the seam together.
Slice the log into 1" thick slices.
Randomly place the rolls in the prepared pan.
Preheat your oven to 350℉.
Allow to rise for about 45 minutes or until puffy and almost doubled.
Whisk the egg and brush over the top of the risen rolls.
Bke the bread for 30-35 minutes. If the top starts to get too brown, cover the top with a pice of foil and continue baking.
Remove from the oven and place on a rack to cool for 10-15 minutes.
Remove from the pan and serve warm.
