** Plan ahead as this step needs to be done the night before!Spread softened butter into a 9x13 baking dish, or you can spray with nonstick spray. Place the brioche bread cubes into the prepared baking dish and allow the bread to sit out overnight, uncovered. 1 loaf (20 oz) sliced brioche bread
In a large mixing bowl, whisk together the sweetened condensed milk, eggnog, light brown sugar, eggs, vanilla extract, cinnamon, and nutmeg. Pour the mixture over the bread and allow it to rest for 1 hour, uncovered at room temperature, for the bread to absorb all the liquid.

Preheat the oven to 350℉.
Cover the casserole pan with aluminum foil. Bake for 30 minutes. Then uncover and cook for an additional 30-40 minutes until it's golden brown.
In a small saucepan, bring the sweetened condensed milk, eggnog, cinnamon, and nutmeg to a simmer over medium-high heat.
