Combine warm milk and sugar in a mixing bowl, stirring until sugar dissolves. Sprinkle yeast over mixture and let sit for 5-10 minutes until foamy.

Add melted butter, eggs, vanilla, and salt to the yeast mixture. Gradually mix in flour until a sticky dough forms.

Transfer dough to a floured surface and knead for 5-7 minutes until smooth and elastic.

Place dough in a greased bowl, cover with a towel, and let it rise in a warm area for about 1 hour or until doubled in size.

In a small saucepan, melt together brown sugar, butter, and heavy cream, stirring until smooth. Remove from heat.

Once the dough has risen, roll it out into a rectangle. Brush with melted butter and sprinkle with sugar and cinnamon. Scatter chopped pecans over dough.

Roll up the dough tightly and cut into 12 equal pieces. Place in a greased baking dish close together.

Pour prepared caramel sauce over buns and let them rise for another 30 minutes.

Preheat oven to 350°F (175°C). Bake for 25-30 minutes or until golden brown.

Allow buns to cool for a few minutes before flipping onto a serving platter. Pull apart and enjoy!
