The night before you want this ready, butter or oil the inside walls of a crock pot really well.
Cut up about 1/2-3/4 a loaf of bread into large chunks. Thicker slices of bread will work better, but you can use just about any type. Place in buttered crock pot.
Mix or beat together eggs, milk, vanilla, maple syrup, and cinnamon in a large bowl.
Pour the mixture over the bread in the crock pot. Do not fully submerge, about 3/4 of the bread will be covered.
Sprinkle over the top brown or coconut sugar.
Add slices of butter to the top.
Cover and set on low for 8-10 hours.
In the morning, scoop out to serve.
Top with your favorite toppings, powdered sugar, fresh fruit, whipped cream, or maple syrup.
