In a large bowl, whisk together eggs and half and half until fully combined. Add vanilla extract, ground cinnamon, brown sugar, and salt. Mix until smooth.

Poke several holes in the bottoms of each King's Hawaiian Roll. Dip each roll into the custard mixture for about 30 seconds.

Heat a nonstick skillet over medium-low heat and melt butter, coating the skillet evenly.

Place soaked Hawaiian Roll bites in the skillet. Cook each side for about 30 to 60 seconds until golden brown and crispy.

Transfer cooked Hawaiian Roll bites to a serving plate, dust with powdered sugar, and serve warm with fresh berries and maple syrup.
