In a medium sized bowl, mix cream cheese, mayo, bacon crumbles, green onion and half of the cheddar cheese together until combined.

Place the chicken breast in a baking dish and spread the cheese mixture over the chicken. Top with remaining cheddar cheese.

Bake at 350 degrees for 30-40 minutes or until chicken is cooked through (165˚F internal temperature). Garnish with additional bacon and green onions and serve hot!
