Boil macaroni in salted water according to package directions until al dente; drain and set aside.
Season chicken cubes with salt and 1 tsp pepper, dredge in flour, and fry in oil over medium-high heat until golden brown and internal temperature reaches 165F.
In a small saucepan, combine honey, soy sauce, and cracked black pepper; simmer over medium heat for 5 minutes until thickened, then toss fried chicken in the glaze.
In a large heavy-bottomed pot, melt butter over medium heat, whisk in 1/4 cup flour and cook for 2 minutes to create a roux.
Gradually whisk milk into the roux, stirring constantly until the sauce thickens and coats the back of a spoon.
Remove sauce from heat and stir in shredded cheddar, smoked gouda, and garlic powder until the cheese is completely melted and smooth.
Fold the cooked macaroni into the cheese sauce until evenly coated.
Portion the mac and cheese into bowls and top with the glazed honey pepper chicken.
