["Spread the flour in a shallow baking pan. Cover and refrigerate or freeze until needed, at least 45 minutes.", "Use the paddle attachment to whip the cold butter only until it is smooth and slightly fluffy, but still cold. There should be no small hard lumps when you pinch it between your fingers. Scrape the butter into a mound on a piece of wax paper and refrigerate it until needed. Wash the mixer bowl. (Proceed with the recipe right away; too long a delay will re-harden the butter.)", "Dissolve the yeast and 1 teaspoon of sugar in the water in the bottom of the clean mixer bowl, now fitted with the dough hook. Add the remaining 1/3 cup (66 grams) sugar, eggs, yogurt, salt, and flour. Mix on low speed until the ingredients are blended, scraping the bowl as necessary. Turn the speed up to medium (speed 5) and knead for 5 minutes. At the end of the kneading period the dough will be soft, moist, and sticky, and very elastic. All or most of it will be wrapped around the dough hook. Add the cold creamed butter in several large pieces, pushing it into the dough, and beat with the hook until it is well blended. You will need to stop the mixer several times to scrape the dough from the sides of the bowl and pull it completely off of the hook, until the butter appears thoroughly incorporated. Scrape the dough into a bowl, cover, and refrigerate overnight, or up to 24 hours.", "Thoroughly mix the brown sugar, cocoa powder, espresso powder, cinnamon, and salt. Cover and set aside. Grease an 8 to 10 cup tube pan with a removable bottom.", "Scrape the cold dough out onto a well-floured surface. Use a rolling pin to roll the dough into a thin square sheet about 18"" by 18"
