No Yeast Cinnamon Rolls Ready in 45 Minutes

Instructions:

1. Whisk the flour, granulated sugar, baking powder, baking soda, and salt in a large bowl until aerated and perfectly combined.
2. Add the chilled, cubed butter to the flour mixture. Use a pastry cutter or two forks to press the butter into the flour until the mixture resembles coarse crumbs with pea-sized bits of butter remaining.
3. Pour in the cold buttermilk and stir gently with a wooden spoon until a soft dough forms. Do not overwork the dough to keep gluten development minimal.
4. Turn the dough onto a lightly floured surface and pat or roll into a 12x18 inch rectangle. Spread 4 tablespoons of softened butter evenly across the surface.
5. Mix the dark brown sugar, cinnamon, and nutmeg in a small bowl. Sprinkle this mixture evenly over the buttered dough.
6. Roll the dough tightly starting from the long edge. Use unflavored dental floss or a sharp serrated knife to cut into 12 even rolls.
7. Place rolls into a greased 9x13 inch baking dish. Bake at 375°F (190°C) for 25 minutes until the tops are golden brown.
8. While baking, whisk together softened cream cheese, butter, powdered sugar, vanilla, and milk until smooth. Spread the velvet glaze over the rolls while they are still warm.
