Nutella Souffles

[amd-recipeseo-recipe:57]
Make-Ahead Note: The soufflé mixture can be made up to 2 days ahead. Just fill the ramekins and refrigerate uncovered until cold, then cover and keep chilled until you’re ready to bake them. Alternately, you can pop them in the freezer and keep for longer. Just move them into the refrigerator the day before you plan on baking them off.
