Whisk together eggs milk vanilla extract cinnamon sugar and salt in a large bowl until smooth
Slice the Hawaiian rolls in half if you prefer smaller pieces or keep them whole for a pull-apart style
Dip each roll into the egg mixture for 10 to 15 seconds per side allowing it to soak slightly but not get too soggy
Heat a non-stick pan or griddle over medium heat and melt butter
Place the soaked rolls onto the pan and cook for 2 to 3 minutes per side until golden brown and slightly crispy
Remove from heat and serve immediately with your favorite toppings such as maple syrup fresh berries or powdered sugar
