what's in lucky charms cereal
Then, we checked the nutritional facts for Frosted Cheerios (a comparable, if imperfect, analogue for the boring part of Lucky Charms cereal) and found that they contain 9 grams of sugar per cup. That leaves 2.3 grams for the nine marshmallows in an average serving size, or 0.25 grams of sugar per marshmallow. We then dug through our cereal boxes for Lucky Charms marshmallows, and found that there are about 290 marshmallows in a 10 oz cup. So thatâs about 72.5 g of sugar in 10 ounces of marshmallows, or 7.2 g of sugar per ounce.
