  1. Heat oven to 350 degrees F.
  2. 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.
  3. 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.
  4. Bake for 30 minutes, or until marshmallows have turned golden brown.
