Serve this to your guests for a weekend or Christmas brunch, you will get rave reviews, make certain that you print out this recipe, as everyone will be asking for it lol! If you are serving more than 6 people prepare two separate recipes and bake in two 13 x 9-inch pans. Make certain the your croissants are large size and at least one day old. Jack Daniel's bourbon whiskey is good to use for this recipe. Plan ahead this needs to chill for 1 hour before baking. I prefer to bake this in a water bath although it is not really needed to do so, but the bread pudding with have a fluffier softer texture if baked in a water bath, if you are making this to serve to company I would strongly suggest baking in a water bath, the choice is up to you!
