Cut French bread into cubes and place the bread cubes in a large mixing bowl. In a separate mixing bowl, whisk together large eggs, milk, cinnamon, and vanilla extract.
Pour the egg mixture over the bread and stir until the bread is coated well with the egg mixture.
Cover and refrigerate for at least 4 hours (but we usually refrigerate overnight).
Spray a 6 quart crock pot with a non-stick cooking spray and pour the bread mixture into the crock pot.
Spread out the mixture evenly into the bottom of the crock pot. In a small bowl, mix together softened butter, brown sugar, and the remaining cinnamon to make a crumble topping.
Crumble the topping over the top of the bread mixture in the crock pot.
Cover and cook on low for 4 hours or on high for 2 hours until the mixture is cooked through.
Let the French toast set for 20-30 minutes until it sets and then it’s ready to serve and enjoy!
Notes
This French toast is great served with maple syrup, powdered sugar or fresh berries. Refrigerate the leftovers in an airtight container for up to 5 days.
