In a large bowl, beat together the milk, heavy cream, eggs, brown sugar, cinnamon and salt.
Spread melted butter onto a large sheet pan that has at least a 1/2 lip around the edge. (I use a 16"x 22" sheet pan)
Dip roll slices into the mixture, allowing mixture to soak slightly. Then line them along the buttered sheet pan. Repeat the dipping process with the remaining slices. Sprinkle the tops with a little more cinnamon, if desired.
In a preheated oven, bake at 425°F for 10 minutes. Remove from oven and flip each piece over. Cook 10-15 minutes more.
Serve hot with your favorite toppings, such as maple syrup, fruit or whipped cream.
Enjoy!
