In a small bowl combine the soy sauce, brown sugar, garlic, cornstarch, ginger and sesame oil. Heat a cast iron pan over medium high heat. Add a splash of cooking oil and cook the beef for few minutes. Add the soy sauce mixture with the beef and let sizzle a little bit then set aside.
Clean the pan real quick and return to medium high heat. Melt butter to the pan then add rice. Do not disturb rice right away. Stir rice nicely, season with garlic-salt powder and cook until lightly crispy about 5 minutes.
Heat a non stick pan to low and cook the eggs sunny side up.
Place a portion of the rice in a serving bowl. Top with beef, carrots, radishes, cucumber, green onions, 1 egg, the gochujang sauce and toasted sesame seeds. Yum!
