1. Preheat oven to 350°F (175°C). Generously grease a 9- or 10-inch fluted tube pan.
2. Cut each biscuit into 4 pieces and shape into balls. For homemade dough, mix warm milk, yeast, and sugar; rest 5 minutes. Add eggs, butter, salt, and flour, then knead 5-7 minutes until elastic. Let dough rise 1-2 hours until doubled, then punch down and form 40-45 dough balls.
3. Combine granulated sugar and cinnamon in a bowl. Roll each dough ball in the cinnamon sugar until evenly coated. Arrange in the prepared pan.
4. Melt ½ cup butter, mix with brown sugar, and pour over the dough balls. Add 1 teaspoon vanilla to glaze for extra flavor.
5. If using homemade dough, let rest for about 20 minutes for a slight rise.
6. Place the pan on a baking sheet and bake for 35 to 45 minutes, or until golden brown and firm.
7. Let cool for 5-10 minutes before inverting onto a serving platter.
