After the dough has risen to double in size, you are ready to roll it out. Flour your worktop and place the dough on it. Flour the top of the dough so it doesn't stick to your rolling pin. Roll out the dough into a large rectangle, 15x20 inches. After you have rolled the dough, spread the butter, brown sugar and cinnamon all over it. Roll up the dough from the longest side and cut it into 12 even slices.
