In a medium skillet, create a roux with the butter and flour. Cook, stirring, until the roux is light brown.
Slowly whisk in the broth.
Add the sugar and bring to a simmer.
Reduce heat to medium and cook until reduced by half.
Stir in cream and pepper. Return to a simmer and cook for an additional 5 minutes.
