Place one stick of butter into a pan over medium heat. After butter melts and cooks for a few minutes it will begin to brown. Gently swirl the butter until it is a deep brown. Place browned butter in freezer to chill quickly while you prepare the dough.
Mix the dry ingredients for the dough in a large bowl.
Cut in the butter until the flour has a crumbly consistency. Add all remaining dough ingredients and mix just until all liquid is integrated.
Roll out dough on lightly floured surface to 1/2 inch thickness. Spread dough surface with 4 tablespoons browned butter then sprinkle with sugar and cinnamon to create the filling.
Roll up to enclose the filling, similar to a jelly roll. Use very sharp knife to cut out 12 biscuit slices.
Bake on parchment paper at 450 degrees for 15 minutes.
Cool biscuits on rack for 10 minutes. Blend all frosting ingredients in a small bowl. Spread over rolls.
