Mix warm milk, a pinch of sugar, and yeast. Wait for 5-10 minutes till it's foamy.
Combine pumpkin puree, melted butter, brown sugar, and vanilla with the yeast mix. Add flour and salt bit by bit to form the dough.
Make the dough smooth, then let it rise in a greased bowl till it's twice as big.
Mix diced apples, cinnamon, nutmeg, and brown sugar together.
Flatten the dough, spread melted butter, then sprinkle the apple mix.
Roll the dough tightly into a log. Carefully slice the log into individual rolls.
Grease your casserole dish and arrange the sliced rolls in the dish, leaving space between them for rising.
Cover the casserole dish and let the rolls rise for about 30 minutes, or until they've puffed up and are touching each other.
Preheat your oven and then bake the casserole of sliced Pumpkin Apple Cinnamon Rolls. The baking time might be slightly adjusted from the original recipe, so keep an eye on them. They should turn a lovely golden brown.
After taking the casserole out of the oven, you can drizzle the warm rolls with a simple glaze made of powdered sugar and milk.
