Preheat the oven to 400°F (200°C). Pat chicken dry and season with salt and black pepper.
In a small saucepan over medium heat, melt ¼ cup butter. Add minced garlic and sauté until fragrant.
Stir in honey and black pepper until smooth. Remove from heat.
Place chicken in a baking dish and pour half the glaze over it. Bake for 25-30 minutes, until internal temperature reaches 165°F (75°C).
Meanwhile, boil salted water in a large pot and cook macaroni until al dente. Drain and set aside.
In another pot over medium heat, melt 2 tbsp butter. Stir in flour to create a roux; cook for about 1 minute.
Gradually whisk in milk until the mixture thickens; add shredded cheddar cheese until melted and smooth.
Serve chicken drizzled with remaining glaze alongside mac and cheese.
