Tear the King's Hawaiian Rolls into quarters and place them in the crockpot.
In a mixing bowl, whisk together the bourbon, eggs, melted butter, salt, brown sugar, and cornstarch until smooth and well combined.
Pour the custard mixture evenly over the torn rolls. Add the chopped peaches on top.
Gently fold everything together, making sure the custard reaches the bottom of the crockpot so nothing sticks or burns.
Cover and cook on low for 2 hours, stirring occasionally to prevent sticking and to ensure the bread soaks evenly.
Serve warm with bourbon glaze drizzled over the top.
