Preheat oven to 350°F. On the top of the french bread, slice about 2 inches deep. Remove the top of the bread and hallow out the center. Save the scraps for croutons or breadcrumbs.
Combine the cream cheese and buffalo sauce. Mix until combined. Then stir in the chicken, 1/2 cup cheese and garlic powder. Salt and pepper to taste.
Spoon the filling into the hallowed bread. The add the remaining 1/2 cup shredded cheese. Bake for 20 to 25 minutes or until the top is bubbly.
Remove from oven and let bread rest 5 to 10 minutes before slicing.
Homemade French bread: You can buy store bought bread (I love Sprouts) or make your own. This homemade French bread works great with day old French bread. You can even cut the recipe in half and use it for half a loaf. Hallowed bread:Don't toss out the center of the bread. Use it to make breadcrumbs or homemade croutons. Variation:You can also use BBQ sauce in place of buffalo sauce.
