Cinnamon swirls

Just after christmas I bought a cinnamon bun kit and after getting up early to take delivery of a microwave thought I would make them! Only problem the flat is not really warm enough for the dough to perform well and not sure the oven is the right temperature. Instead of 15-18 mins it took more like 25-30 mins! First taken out underdone but hope these are better! Added some butter icing on top after photo taken!
