                In a big mixing bowl, toss together the flour, sugar, yeast, and salt. Slowly pour in the warm water, stirring as you go, until the dough comes together.

                Transfer the dough onto a floured counter. Knead by hand for roughly 10 minutes until you've got a smooth, stretchy ball.

                Roll the dough flat into a rectangle, smear it with softened butter, and fold it into thirds. Roll and fold two more times before chilling it for an hour.

                Cut the dough into 12 sections. Take each piece, roll into strips, and coil them neatly into a muffin tin that's greased.

                Put the muffin tin somewhere warm and leave the dough to puff up until it doubles in size—takes about an hour.

                Pop the tray in the oven at 375°F (190°C) for 20 minutes. You're done when they're golden and lovely.

                Toss cinnamon and sugar in a shallow dish. While they're warm, roll the pastries in this mix so they’re nicely coated.
