Ingredients:
- 1 cup (240 ml) Warm Whole Milk, approximately 105–115°F
- 2 ¼ teaspoons Active Dry Yeast (1 standard 7g packet)
- ¼ cup Granulated Sugar, plus 1 teaspoon for yeast
- 2 Large Eggs, room temperature, lightly beaten
- ½ cup (113 g) Unsalted Butter, softened to room temperature (for dough)
- 1 teaspoon Fine Sea Salt
- 3 ½ cups (420 g) All-Purpose Flour, plus extra for dusting
- ¼ cup (56 g) Unsalted Butter, melted (for filling)
- ½ cup (110 g) Light Brown Sugar, packed (for filling)
- 1 tablespoon Ground Cinnamon (for filling)
- 1 tablespoon All-Purpose Flour (for filling)
- 1 cup (120 g) Icing Sugar, sifted (for glaze)
- 2–3 tablespoons Whole Milk (for glaze)
- ½ teaspoon Vanilla Extract (for glaze)
Instructions:
- Activate Yeast: Combine the warm milk, 1 teaspoon of sugar, and the yeast in a small bowl. Stir gently and let sit for 5–10 minutes until frothy (proof the yeast).
- Combine Wet Ingredients: In the stand mixer bowl, whisk the remaining ¼ cup sugar, salt, and softened butter. Add the beaten eggs and the activated yeast mixture. Mix briefly until just combined.
- Mix Dough: Add the flour, half a cup at a time, mixing on low speed until a shaggy dough forms.
- Knead: Knead using the dough hook for 8–10 minutes (or knead by hand for 12–15 minutes) until the dough is smooth, elastic, and passes the windowpane test.
- First Rise (Bulk Fermentation): Place the dough in a lightly oiled bowl, turning to coat. Cover tightly. Let rise in a warm, draught-free spot until doubled in size (60–90 minutes).
- Prepare Filling: While the dough rises, combine the brown sugar, cinnamon, melted butter, and 1 tablespoon of flour in a small bowl. Mix thoroughly until a thick, spreadable paste forms.
- Punch Down and Rest: Gently punch down the risen dough to release the air. Turn it out onto a lightly floured surface. Cover and let rest for 10 minutes to relax the gluten.
- Roll and Spread: Roll the dough into a large rectangle, approximately 18 x 12 inches. Spread the cinnamon filling evenly over the surface, leaving a ½ inch border along the longest edge.
- Roll and Seal: Starting from the long edge opposite the clean border, tightly roll the dough into a log. Pinch the seam shut very securely.
- Second Rise (Proofing): Place the rolled log seam-side down into the prepared 9x5 inch loaf tin. Cover loosely. Let rise again in a warm spot for 45–60 minutes, or until the loaf looks puffy.
- Bake: Preheat oven to 350°F (175°C). Bake the loaf for 35–40 minutes. If the top begins to brown too quickly, loosely tent it with foil after 20 minutes.
- Check Doneness: The loaf is done when the internal temperature reaches 200–205°F (93–96°C).
- Cool: Remove the loaf from the oven and immediately turn it out onto a wire rack. Let cool for at least 30 minutes before glazing or slicing.
- Mix Glaze: Whisk together the sifted icing sugar, vanilla, and milk until smooth and pourable.
- Drizzle: Drizzle the glaze generously over the cooled loaf. Allow the glaze to set slightly before slicing and serving.
