Using a serrated knife, cut slices into the bread, going ¾ of the way down but not fully through. Criss-cross the slits to make a grid of slices.
In a saucepan melt the butter, add in the hot sauce and minced garlic, stirring to combine. Add in the shredded chicken and toss to coat.
Carefully pull apart the slices of bread and stuff the buffalo chicken mixture down into the bread. Then stuff the shredded cheese into the bread as well.
Bake for 15-20 minutes or just until all is heated through, the cheese has melted and the top of the bread is getting crispy. Serve warm.
