Mix the pumpkin, milk, coconut sugar, eggs and spices in a large bowl. Whisk together until well combined.
Add the bread in the bowl and coat all the pieces. Cover and put in the fridge allow the custard to sink into the bread. Stir occasionally to allow it to soak evenly. If possible allow to sit for an hour. It will work without this step, but this allow the bread to get more evenly coated.
Spray a Crock Pot with cooking spray. Transfer the mixture to the crock pot making sure the bread is evenly spread along the bottom.
Cook on low for 7-8 hours. Check at 7 hours to make sure it's not burning.
Serve with your favorite syrup and a side of fruit!
