Cook the macaroni according to package instructions until al dente.
In a large skillet, heat olive oil over medium heat and add diced chicken.
Season the chicken with salt, black pepper, and cayenne pepper, and continue cooking until no longer pink.
Reduce heat, then slowly pour in the heavy cream, stirring to combine.
Stir in the shredded cheddar cheese and honey, mixing until smooth.
Combine the cooked macaroni with the creamy chicken mixture and stir to coat evenly.
Transfer the mixture to a greased baking dish and top with additional cheddar if desired.
Bake in a preheated oven at 350°F for 20 minutes or until bubbly and golden.
Garnish with sliced green onions before serving.
