Growing up, marshmallow treats were one of my favorite snacks EVER. The crunchy, chewy texture, the light sweetness and marshmallow flavor – I could never eat just one. As I got older, I realized that they’re pretty simple to make (just be prepared for a sticky mess), and that you can totally adjust them based on preference. I started adding chocolate, adding more marshmallow (chewier) and less (crunchier), and mixing up mix-ins.
Thus, we landed on these Lucky Charms marshmallow treats. Lucky Charms are delicious as is, between the lightly sweet cereal pieces and the crunchy marshmallows. The cereal’s flavor profile makes it a perfect base for marshmallow treats, and, as a bonus, it looks super fun.
It’s a fun treat to whip up for (and/or with) kiddos, it’s great to bring to parties, and it keeps well in an airtight container at room temp. You’ll be feeling lucky as ever when you’ve got a whole batch of these at home!
