Spray the inner liner/pot of the slow cooker with cooking spray or line it.
Crack the eggs and add the brown sugar to the pot of the slow cooker.
Whisk it until blended then add the heavy cream and milk, and continue to whisk. (Skim and 1% are too watery, so use whole or 2% milk.)
Add the cubed baguette. With a fork, carefully press the bread down so that it is fully soaked in the egg and milk mixture.
Sprinkle with chocolate chips.
Cover and cook on HIGH for 2 hours.
Add the Hershey Bars, Crushed Graham Crackers, and Mini Marshmallows.
Cover for 3-4 minutes to melt and then serve.
Notes
Any crusty bread will work, but I used a baguette for this recipe.You can add nuts as well like 1/2 cup of chopped pecans.Leftovers will store in the fridge for 3 days in an air-tight container.Warm up in the air fryer or microwave for 3-5 minutes.
