St. Patrick's Day is coming up which means it's time to add some clovers, rainbows, and pots of gold to our treats! It's also Cereal Day on March 7th so these Lucky Charms cookies are a great way to celebrate both! They're filled with marshmallows from Lucky Charms cereal and are covered in sprinkles! They taste like magically delicious, soft & cakey funfetti cookies! They're so nostalgic for me, bringing back my childhood days of eating Lucky Charms for breakfast and indulging in sprinkle-covered sugar cookies! Kids are sure to love these!
(Side note: do you say "confetti" or "funfetti", and is there even a difference?!)
My first attempt at making these cookies included both the cereal and the marshmallows. However, the cereal's texture did not hold up well in the cookies so I eliminated them immediately! Have you ever picked the marshmallows out of a box of Lucky Charms cereal? After ordering colorful marshmallows I became impatient waiting for them so I took matters into my own hands (in case you're wondering, it takes about 5 minutes to sort out 1 cup of marshmallows from the cereal box).

The next question I asked myself was, "are these cookies colorful enough with just the marshmallows?!" And honestly, the answer is pretty much always "no!", which led to me rolling the cookie dough balls in sprinkles. These sprinkles are my favorite because the colors are beautiful and they're made with all natural dyes! I also thought they matched the marshmallows really well!
Lucky Charms Cookie Sandwiches!
To make these even more fun, I turned them into cookie sandwiches! I did so using vanilla buttercream. For this, I mixed together some powdered sugar, butter, vanilla extract, and heavy whipping cream. I usually eyeball it, but if you'd like to follow a recipe I'd recommend Sally's buttercream frosting! The buttercream could easily be dyed to add even more color. You could also make ice cream sandwiches instead of using buttercream! They would pair well with anything from plain vanilla ice cream to something fruity like blue moon ice cream (AKA my all-time favorite)!
