Mix all the ingredients (except the bread) in a bowl. Whisk until eggs are combined. Then in a 9 x 13 baking dish put in the bread cubes. (I have made it with normal bread and french bread, thicker more dense bread is better for this recipe so go with the french bread) Then after the bread is in the baking dish pour over the egg mixture. Mix it all together. Cover. and Put in fridge OVERNIGHT.
Mix the melted butter and brown sugar together. Then grab a cookie sheet and arrange the bread that has soaked overnight on the cookie sheet in a single layer. Then drizzle the butter and brown sugar mixture over the bread.
Bake at 350 for 20 minutes. If the sugar hasn’t caramelized then after 20 minutes turn it on broil for a minute. Then serve!
