Add powder sugar, cinnamon, brandy and buttershots.
Increase heat to medium low.
Allow the mixture to gently boil for a minute or two.
NOTE: This mixture will have a more caramel tone to it instead of the buttery color of that served in Don Pablo's. I'm guessing it's due to the cinnamon. I'm going to try it with a cinnamon liqueur and see if that makes a difference. Will post changes when I do. (recipe courtesy of copycat recipes at recipelink)
