Cook the macaroni according to the package instructions until al dente. Drain it, then return it to the pot to keep warm.

Toss in the butter, milk, and shredded cheese. Stir until the cheese melts and the mixture becomes creamy. Season with salt and pepper to taste.

Heat a skillet over medium heat. Place a tortilla in the skillet and scoop a generous portion of the mac and cheese mixture onto one half.

Fold the tortilla over, and cook until it turns golden brown. Flip it over and repeat on the other side until both sides are evenly crisped.

Continue with the remaining tortillas and filling, creating a delightful assembly line of cheesy goodness.

Once all quesadillas are done, cut them into wedges, and serve them warm with your choice of toppings.
