Preheat the oven to 375 degrees. Butter the bottom and sides of a 10” springform pan.
In a food processor or blender, grind up the King’s Hawaiian Bread Sweet Sliced Bread into a fine crumb.
In a bowl, toss the bread crumbs together with the melted butter and the sugar. Press into the springform pan.
In the bowl of an electric mixer stir together the egg yolks, brown sugar, sugar, pumpkin, vanilla, cinnamon, nutmeg and salt. Set aside.
In a separate bowl of the electric mixer, beat the egg whites until stiff.
Fold the egg whites into the pumpkin mixer and pour on top of the breadcrumb crust in the pan.
Bake for 45 minutes. Let cool and release the springform.
