Heat up in a large saucepan over medium heat. Add laksa paste and stir fry until fragrant, about 1 minute.
Add coconut milk, chopped chillis, ginger powder, fish sauce, chicken broth and water. Give everything a stir and bring mixture to a simmer. Cover and let simmer for 10 minutes.
While the soup is simmering, cook vermicelli and Hokkien noodles according to package instructions.
After 10 minutes, taste your soup and adjust seasoning if needed. Then, add prawns, sliced fish cakes and bok choy to the soup. Give everything a stir and let simmer until prawns turn pink and are no longer translucent.
Assemble your laksa noodle soup by diving cooked noodles between two serving bowls. Top each with bean sprouts, pawns, fish cake, and bok choy. Pour soup over the two bowls. Garnish with chopped chilli and lime wedges. Enjoy!
