Pumpkin Cinnamon Rolls with Caramel Glaze

I happened upon this recipe, and I had to try it!  It does, after all, combine two of my most favorite things -- pumpkin and cinnamon rolls!  They were a hit with everyone I shared them with and I'm excited to make them again (maybe tomorrow!).  

PUMPKIN CINNAMON ROLLS WITH CARAMEL GLAZE
2-3/4 to 3-1/4 cups all-purpose flour, divided
1 package (1/4 ounce) active dry yeast
1/2 cup solid-pack pumpkin
2/3 cup milk
2 tablespoons sugar
4 tablespoons butter, divided
1/2 teaspoon salt
1 egg, beaten
1/2 cup packed brown sugar
1 teaspoon ground cinnamon
1/2 cup Hershey's cinnamon chips (optional)

In a bowl, combine 1-1/2 cups flour and yeast; set aside.
In a saucepan, heat and stir pumpkin, milk, sugar, 2 tablespoons butter and salt until warm (120°-130°) and butter is almost melted.
Add to flour/yeast mixture along with egg.
Beat on low speed for 30 seconds. Beat on high speed for 3 minutes.
Stir in enough remaining flour to make a moderately stiff dough.
Knead on a lightly floured surface until smooth and elastic, about 6-8 minutes.
Place in a greased bowl, turning once to grease top.
Cover and let rise until doubled, about 1 hour.
Roll into a 12-in. x 10-in. rectangle.
Melt remaining butter; brush on dough.
Combine brown sugar and cinnamon; sprinkle over dough.
Sprinkle cinnamon chips on top.
Roll dough, jelly roll style, starting with the longer side.
Cut into 12 equal slices.
Place rolls, cut side down, in a greased 13-in. x 9-in. baking pan (I like gooey bottom cinnamon rolls, so I usually make a syrup of brown sugar and warm water and put that in the bottom of pan before placing the cut rolls in the pan).
Cover and let rise until doubled, about 30 minutes.
Bake at 375° for 20-25 minutes or until golden brown.

For glaze:
4 Tbs butter
1/2 c. packed brown sugar
2 Tbs milk
1/2 tsp vanilla
1/2 - 2/3 cup powdered sugar

For frosting, melt butter in a saucepan; stir in brown sugar and milk.
Cook and stir over medium-low heat for 1 minute.
Stir in vanilla, salt and 1/2 cup confectioners' sugar; beat until well blended.
Add more sugar, if necessary, to achieve desired consistency. Drizzle over rolls.

Yield: 1 dozen.
