Sweet potato fluff is a sweet potato casserole recipe for marshmallow lovers. It is all about the perfectly toasted meringue that graces the top of the casserole.
Preheat oven to 375 F degrees. Pierce the sweet potatoes all over with a fork. Place on a baking sheet and bake for about 40 minutes or until tender. Allow the sweet potatoes to cool slightly then slice down the middle and remove skin.
Place the sweet potato flesh in a large bowl. Add the eggs, melted butter, brown sugar, vanilla, bourbon (if using), salt, nutmeg, and cinnamon to the sweet potatoes then beat with a hand mixer until well combined.
Increase the oven temperature to 400 degrees. Spread the sweet potato mixture into a baking dish and smooth out. Top with the marshmallow fluff, swirling the meringue to create peaks.
Bake the pie for 5-7 minutes until the meringue is set and starts to turn golden brown.
Marshmallow Meringue
Add the egg whites, cream of tartar, and a pinch of salt to a large glass bowl. Using a hand mixer, beat the egg whites, until foamy. Add the sugar, 1 tablespoon at a time, and beat until stiff and glossy peaks form.
Scoop the marshmallow creme into a large bowl. Add ½ the beaten egg whites to the marshmallow creme and stir with a rubber spatula to lighten the marshmallow creme. It will be extremely sticky. Gently fold in the remaining egg whites.
