Boil elbow macaroni in well-salted water until just shy of al dente, about 6 minutes. Drain and set aside.

Melt butter in a large saucepan, whisk in flour, and cook for 1 minute. Pour in milk slowly, whisking until smooth. Simmer until thick enough to coat a spoon, then stir in shredded cheddar and Monterey Jack until melted. Season with garlic powder, cayenne, salt, and pepper.

Fold the drained pasta into the hot sauce, spread into a parchment-lined 9x13-inch dish, cover, and refrigerate at least 3 hours or overnight. The base must be cold and solid to hold its shape.

Use a 2-tablespoon scoop or a sharp knife to portion the cold mac into 24 balls or squares. Compress gently so they hold together.

Fill three shallow dishes with flour, beaten eggs, and panko. Dredge each bite in flour, dip in egg, and roll in panko, pressing lightly so the crumbs adhere.
06 -
Heat 2 inches of oil in a heavy pot to 350°F. Fry 4 to 5 bites at a time, turning once, until deep golden, 3 to 4 minutes. Drain on a paper towel-lined plate and sprinkle with salt while hot.

Pile the fried mac and cheese bites on a platter and serve hot with ranch or marinara for dipping.
