In a shallow dish, whisk together the half-and-half, egg yolks, brown sugar, vanilla extract, cinnamon, salt, and nutmeg. Preheat a greased griddle over medium heat.

Dip each slice of brioche into the egg mixture, allowing it to soak for 5 seconds on each side. Cook on the griddle until golden brown on both sides.

Serve with your choice of toppings such as whipped cream, berries, or maple syrup.
