1
Sift flour, cinnamon, baking powder, and salt in a medium basin. Set aside. Fork-mix brown sugar, cinnamon, and melted butter in a small bowl. Like cinnamon roll filling, it should be moist. Set aside.
2
Mix butter, brown sugar, and white sugar. Beat butter for 2 minutes until frothy. Scrape bowl and add vanilla. Add eggs one at a time. Between eggs, scrape bowl.
3
Combine ⅓ dry ingredients and 1⁄2 buttermilk. Beginning to mingle. Next, add ⅓ of the dry ingredients and remaining buttermilk. Combine. Stir in remaining dry ingredients and sour cream. Mix and scrape bowl for 10-15 seconds.
4
Add half the cinnamon roll filling to the batter and gently fold with a rubber spatula. Fill muffin pans ¾ full with an ice cream scoop for easy pouring. Sprinkle some cinnamon roll topping on each muffin.
5
Using a giant pan, bake at 425°F for 10 minutes and a 12 cup muffin pan for 8. Lower the heat to 375°F and bake the big pan for 10-12 minutes and the 12 cup muffin pan for 6-8 minutes. Bake the muffins until a toothpick comes out clean.

After baking, let the muffins sit in the pan for 10 minutes before moving them to a rack to cool. Let the muffins cool all the way down before you make the glaze.

Cream cheese should be light and frothy after 1 minute on high with a hand mixer. Add sifted powdered sugar and mix on low until mixed. Turn up and beat for 30 seconds on high.
