First mix in the brown sugar and cinnamon in a bowl and leave aside.
Next butter a round tin (roughly 9 inches) and preheat the oven to 425 degrees Fahrenheit (220 degrees Celsius).
Take a large bowl, and put in it Bisquick mix, granulated sugar, milk and egg. Take a spoon and mix well to combine.
Once you’ve mixed till it is all combined, the rest of the procedure is a little different from usual dough making or handling.
While you put the rolls in to bake (which should take about 20-25 minutes), place the powdered sugar and the whipping cream in a bowl.
Mix to combine, and spread over the rolls while they’re still hot.
