In a large mixing bowl, whisk together the eggs, milk or half-and-half, vanilla extract, brown sugar, cinnamon, and salt until smooth and creamy.

Poke a few holes in each King’s Hawaiian roll and slice each in half to prepare for soaking.

Soak each slice of the halved rolls in the custard for 30 seconds on each side.

Preheat a nonstick skillet over medium heat and melt the butter.

Cook the soaked rolls cut-side down in the skillet for 3-4 minutes until golden brown, then flip to cook the other side.

Transfer to a warm plate, garnish as desired, and serve warm.
