In a mixing bowl, combine warm milk with yeast and let sit until frothy (about 5 minutes). In another bowl, mix flour, sugar, and salt.

Add melted butter and eggs into the yeast mixture once frothy. Gradually stir in the flour mixture until dough forms. Knead until smooth (about 6 minutes) and place in a greased bowl covered with plastic wrap.

Allow the dough to rise in a warm area until doubled in size (approximately 1 hour).

Punch down the risen dough and roll it into a rectangle (about an inch thick). Spread softened butter over the surface and sprinkle with cinnamon-sugar.

Roll up the rectangle from one long side into a log shape, pinch seams closed, and form into a circle. Hide a small plastic baby inside if desired.

Preheat oven to 350°F (175°C). Place shaped cake on parchment-lined baking sheet; let rise again for about 30 minutes before baking for approximately 35 minutes or until golden brown.

Drizzle with glaze made from powdered sugar mixed with water/milk.
