What is the easiest way to measure Marshmallow Fluff when making a recipe?
Weigh the full container, then remove the desired measured amount by weight. Remember, a cup of Fluff weighs slightly more than 3 oz. A 7 1/2 oz. jar contains about 2 1/2 cups, and a 16 oz. container has about 5 cups. Finally, most recipes do not require precise measurements of Marshmallow Fluff to be successful.
