White Chocolate M&M's are already a delightful snack, but marshmallow has been added to the mix for an even better treat. White Chocolate Marshmallow M&M's are officially on shelves, and they're available exclusively at Target as part of its new lineup of Easter candy. The Spring-themed M&M's come in pastel colors and pretty purple packaging, and if you're like me, you'll either devour the bag or use it for a fun upgrade to blondies [1], cookies [2], or edible cookie dough [3]. Previous springtime M&M's flavors have included Vanilla Cupcake [4] and Orange Vanilla Cream [5], and honestly, this sounds like the best yet!
