- 2 teaspoons vanilla extract
- 2 teaspoons cinnamon (divided)

Instructions
- Step 1: Preheat your oven to 425 degrees Fahrenheit. Butter a 13×9 inch baking pan and set it aside.

- Add a handful of fresh berries or chopped nuts for texture and flavor.
- Let the casserole soak for an hour or overnight in the refrigerator for a deeper custard infusion.
