# Step-by-Step Guide:
01 - In a large bowl, mix flour, sugar, yeast, and salt until evenly distributed.
02 - Whisk together warm milk, melted butter, and eggs in a separate bowl.
03 - Add wet ingredients to dry ingredients and stir until a shaggy dough forms.
04 - Knead on a lightly floured surface for 7 to 8 minutes, or 5 minutes using a stand mixer with dough hook, until smooth and elastic.
05 - Place dough in a greased bowl, cover, and let rise in a warm spot until doubled in size, approximately 1 to 1.5 hours.
06 - Punch down the dough and roll out on a floured surface into a 12x20-inch rectangle.
07 - Spread the softened butter evenly over the dough. Sprinkle brown sugar and cinnamon over the top.
08 - Cut dough into 5 long strips, stack them, then slice the stack into 6 to 8 even pieces.
09 - Grease a 9x5-inch loaf pan and arrange the stacked pieces vertically with cut sides facing upward.
10 - Cover and let the dough rise until puffy, about 30 to 40 minutes. Preheat oven to 350°F during this time.
11 - Bake for 30 to 35 minutes or until golden brown and cooked through. Cover loosely with foil if browning too fast.
12 - Allow bread to cool in the pan for 15 minutes, then transfer to a rack to cool completely.
13 - Mix powdered sugar, milk, and vanilla extract until smooth and drizzle over warm bread if desired.
