If you don't have cheese rice cakes, just roll up some rice paper and add it, and you can sprinkle cheese on top as a topping—should be fine! (One sheet of rice paper: 5.5g)
Add gochujang, red pepper powder, sugar, soy sauce, and minced garlic to a bowl.
Add water or kelp broth and mix well.
Pour the sauce into a pan and bring to a boil over medium heat.
Stir and simmer until the sauce thickens.
