Marshmallow and Cornflake Sweet Potato Casserole Recipe

Heat oven to 350 degrees F.

Use an electric mixer to whip the sweet potatoes with 1/4 cup butter eggs and egg yolk until smooth and creamy. Add in the pineapple if using then transfer the mixture into a 6-cup casserole dish.

Stir together the cornflake crumbs with 2 tablespoons of butter and brown sugar. Alternating in rows spoon the cornflake crumbs across the top of casserole at a diagonal followed by a row of marshmallows. Repeat until you have 5 rows of the cornflakes and 4 rows of the marshmallows.

Bake for 30 minutes or until marshmallows have turned golden brown.
