Preheat your oven to a cozy 350 degrees Fahrenheit to get things started.
In a large bowl, lovingly combine the warm, cooked macaroni with butter, cheese, salt, and pepper until everything is nicely coated and friendly.
Transfer the macaroni mixture into a greased 1 1/2 quart baking dish, spreading it out evenly like a cozy blanket.
Whisk together the beaten eggs and milk until fully blended, then gently pour this over the macaroni, letting it seep through all the nooks and crannies.
Bake in the preheated oven for 40 to 50 minutes, or until the top is golden brown and the center is set. Patience is key here – it's worth the wait!
