This breakfast casserole was awesome. There are 2 things I really like about this casserole, 1 it was an overnight casserole and 2 the heavenly crunchy cinnamon topping!
It saves so much time having a breakfast casserole that is mixed together the night before and then baked in the morning and this casserole did not disappoint!
The crunchy cinnamon topping reminded me of a coffee cake and the egg custard croissant base reminded me of a favorite dessert of mine.... bread pudding. I love anything baked in an egg custard! The casserole was a recipe that I adapted from Pioneer Woman. In her casserole she uses french bread. I had left over croissants from lunch this week but feel free to use any left over bread you may have on hand.
In the picture above you can see the cinnamon topping I put over the casserole and it was the same topping you would put on top of coffee cake.
