01 - Combine warm milk, yeast, and 1 tablespoon of sugar in a large bowl. Let stand for 5 minutes until foamy.
02 - Add remaining sugar, melted butter, eggs, salt, nutmeg, and cinnamon to yeast mixture. Mix thoroughly to combine.
03 - Gradually incorporate flour until a soft dough forms. Knead for 8–10 minutes until smooth and elastic.
04 - Place dough in a greased bowl, cover, and let rise in a warm location for 1 hour until doubled in size.
05 - Beat cream cheese, powdered sugar, and vanilla extract until smooth and creamy.
06 - Punch down risen dough and roll out on a floured surface into a 10x20-inch rectangle.
07 - Spread cream cheese filling evenly over dough, leaving a 1-inch border around edges.
08 - Roll dough tightly from the long side, pinching seams to seal. Form into a ring on a parchment-lined baking sheet, seam side down. Pinch ends together to close the ring.
09 - Cover and let rise for 45 minutes until puffy and slightly expanded.
10 - Heat oven to 350°F.
11 - Bake for 25–30 minutes until golden brown. Cool completely on a wire rack.
12 - Whisk powdered sugar, milk, and vanilla extract to form a thick glaze. Drizzle over cooled cake.
13 - Immediately sprinkle purple, green, and gold sugars in alternating sections over glaze.
