In a bowl, combine the warm milk, butter, and brown sugar, mixing well. Stir in the yeast and let it sit for about 5 minutes until it becomes frothy.

In a larger mixing bowl, add the flour, cinnamon, nutmeg, and salt. Pour the yeast mixture along with the pumpkin and the egg into the dry ingredients. Stir until the dough comes together.

Turn the dough out onto a floured surface and knead for about 5-7 minutes, until smooth. Place it in a greased bowl, cover, and let it rise in a warm place for 30 minutes, or until doubled in size.

Once the dough has risen, roll it out into a rectangle about 1/4 inch thick. Spread melted butter over the surface and sprinkle with a mixture of sugar, cinnamon, and any additional spices you prefer.

Roll the rectangle tightly into a log and slice into 1-inch pieces. Place them in a greased baking dish, making sure they are close together.

Cover the rolls and let them rise again for about 20 minutes until they puff up.

Preheat your oven to 350°F (175°C). Bake the rolls for 20-25 minutes until they are golden brown.

While they bake, whisk together powdered sugar and milk until smooth.

Drizzle the icing over the warm rolls, and enjoy the fluffy goodness!
