For perfect cream puffs, be sure to heat the oven 10 to 15 minutes before baking. Bake the puffs until they're golden brown and their shape is set. Slitting the puffs with the tip of a knife will allow steam to escape and prevent a soggy interior.
Remove ice cream balls from the freezer 10 minutes before assembling the dessert. This will allow the ice cream to soften slightly for easier eating.
