Allow the potatoes to cool and then peel the skin off

Mash the potatoes and stir through the maple syrup

Mix the flour, baking powder, bicarbonate of soda and salt together.

Add in the flour mix to the mashed potato a little bit at a time,stirring until it becomes a ball. You might need to use your hands to bring it all together to form a dough.

Allow the dough to rest for at least 30 minutes

Using a rolling pin or your hands, roll out the dough onto a floured surface to make a rectangle. It should bethe thickness of a £1 coin

Lightly brush the surface with the oil

Mix the sugar and cinnamon together and sprinkle across the surface

Using a pizza cutter or a knife, cut 3cm strips and then roll them to make a spiral

Put all the rolls next to each other in an oven dish and bake for 30 minutes
