Once risen, tip the dough onto a lightly floured surface.
Roll into a rectangle approximately 30cm x 40cm.
Spread the cinnamon filling evenly over the dough.
Fold the dough in half lengthways.
Cut into 8 equal strips.
Take one strip, gently stretch it, twist several times, then tie into a loose knot, tucking the ends underneath.
Repeat with the remaining strips.
Place the knots onto a lined baking tray, leaving space between each one.
Cover loosely and leave to prove for 30 to 45 minutes until puffy.
