In a saucepan over medium heat, combine butter and brown sugar, stirring constantly until the butter fully melts. Bring to a boil while mixing continuously. After boiling, continue to stir for 10-15 minutes until the mixture reaches 150°C (300°F). Remove from heat and pour onto a prepared sheet pan. Spread evenly with an offset spatula and allow to cool and set for 20 minutes.
