In a large mixing bowl, combine warm milk and active dry yeast. Allow mixture to sit for about 5 minutes until frothy.

Stir in melted butter, pumpkin puree, granulated sugar, and chai spice blend, mixing well.

Gradually add all-purpose flour until a soft dough forms. Knead on a floured surface for about 5 minutes until smooth.

Place dough in a greased bowl, cover with a damp cloth, and let rise for approximately 1 hour.

After rising, punch dough down and roll out into a rectangle about ½ inch thick.

Spread softened butter over the surface of the dough.

Mix brown sugar and chai spice blend in a bowl and sprinkle over the buttered dough.

Roll the dough tightly from one long edge and slice into 1-inch-wide pieces.

Place rolls in a greased baking dish, cover, and let rise for an additional 20 minutes.

Preheat oven to 350°F (175°C) and bake for about 25 minutes until golden brown.

To prepare frosting, beat together cream cheese, powdered sugar, and vanilla extract until creamy.

Drizzle frosting over warm rolls before serving.
