Heat the oven to 350 ℉
On a clean flat floured surface.
Roll out the dough until it is about ⅛-¼ inch thick.****
Spread the filling with an offset spatula over the rolled out dough. Keep the edges clean from filling about 1-2 inches.
Roll the dough up and seal the edges. Place in an Angle Food removable bottom non stick pan.
Seal the two edges together as good as possible. Set the pan/cake into a proofing over, stove or let it sit on the counter. Let it raise for 30-45 minutes to about 25-50% increase.
Whisk the milk and oil well then brush the top of the cake with this mixture.
Place in the oven and bake for 30-40 minutes until golden brown.
Once baked, take the cake out of the oven, let it cool. Place a plate over the Angel food cake pan, and flip over the cake. It should easily fall out onto the plate. Then flip it again onto the serving plate.
Dust with powdered sugar***** just before serving. Slice, serve and enjoy.
