Bring a pot of water to a boil and cook the ramen noodles for about 2–3 minutes until just tender. Drain the noodles, reserving about ¼ cup of the noodle water.
Heat butter and olive oil in a skillet over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant, being careful not to burn it.
Stir in soy sauce, gochujang, sesame oil, paprika, black pepper, and red pepper flakes. Cook briefly to combine the seasonings with the garlic butter.
Pour in the heavy cream and milk, stirring gently until the sauce becomes smooth and slightly thickened. Add a splash of reserved noodle water if needed to loosen the sauce. (moribyan.com)
Add the cooked ramen noodles to the skillet and toss well until every strand is coated with the creamy sauce.
Simmer for another 1–2 minutes until the noodles absorb some of the sauce and the flavors come together. Adjust seasoning according to taste.
Divide the creamy ramen into bowls and top with sliced green onions and sesame seeds. Add your favorite toppings and serve immediately.
