Yeast-free Cinnamon Rolls

This recipe was given to me by a friend. During that time, we were on a yeast free diet but this recipe has remained a favorite due to it's simplicity and the speed in which we get a hot cinnamony treat. The recipe calls for a baking mix. It works fine with any baking mix from gluten free to homemade to Bisquick. We've made it dairy free and with butter instead of the shortening. It's a great recipe that holds up to changes easily.
Omit the frosting and it's a not so sweet afterschool snack. You'll notice I didn't include a frosting recipe but mention it. That's because we rarely eat these with anything else. They are great with extra butter or dunked in cocoa.

Cinnamon Rolls
2 cups baking mix
1/4 cup shortening
3/4 cup milk
½ cup melted butter
1 cup sugar and ½ cup cinnamon combined
oven to 450. Grease 9x12 baking pan.
Cut shortening into mix. Add milk to make dough. Roll into ½ inch thick rectangle on a dusted surface. Baste with melted butter. Sprinkle with cinnamon and sugar. Roll tightly lengthwise into a long roll. Slice 1" thick and place in pan. Bake 12-15 minutes or until done.
If adding icing - do so while still warm so it melts.
