Measure warm water in a jug, then stir in caramel filling and brown sugar. Sprinkle in yeast and stir gently, allow to rest for 5 minutes until foamy.
While resting, add flour and salt to the bowl of a free-standing mixer. Rub in butter until it resembles a fine crumb.
Beat egg and add to flour, along with yeast mixture. Using dough hook, knead for about 10 minutes until dough comes together with an elastic texture. Add a little more flour if too sticky, a teaspoon at a time.
Shape dough into a ball and place in a large lightly oiled bowl. Cover with cling wrap and place in a warm area for 1-2 hours until doubled in size. I like to use a hot water cupboard or a sunny spot.
Remove dough from bowl and knead again lightly on a floured surface to remove any air bubbles. Evenly cut dough into 8 and roll into balls, stretching dough around and pitching tidily at the bottom.
Evenly space dough balls across a lined baking tray, cover with a tea towel and return to a warm area for another 1-2 hours.
Flick oven on to 200 degrees and preheat in preparation for baking.
Beat and egg and brush dough all over. Place in the oven and bake for 10-15 minutes or until golden. Remove and allow to cool.
