Overnight French Toast

Ok, so I couldn't find the website where I got this again but it was so good. I will post it when I find it!

Ingredients:
12 Slices of Bread
1 1/2 cups milk
1 cup brown sugar
1 Tsp cinnamon
5-6 eggs
1/2 cup butter or margarine

Preheat oven to 350. Mix brown sugar and cinnamon in a bowl and set aside.
Whisk eggs and milk until smooth and set aside.
Put butter in the bottom of a 9X13 pan.
Then layer 6 slices of bread. Put half of the sugar/cinnamon on the bread.
Then layer another 6 slices. Pour egg/milk mixture on top. Then layer the rest of the sugar mix.
Refrigerate overnight.
Cook at 350 covered for 30 minutes. Then uncovered for 15.

This was so so good! I hope you enjoy!
