Two favorite Autumn treats, rolled into one! I invented this recipe a couple weeks ago, for my cinnamon-loving boyfriend and I think they turned out pretty well :). I noticed that the pumpkin flavor comes out best after the buns have been chilled. Note: this recipe makes a *lot* of cinnamon buns, so would be great to prepare for gifts or a party/potluck. If you plan on making these for yourself, I would consider halving the recipe. I also eyeballed the filling ingredient quantities and didn't precisely measure them, so the spices/brown sugar/apple juice quantities may need adjusting for your personal taste.
