lucky charms sandwich cookies are the perfect treat for st. patrick’s day!

Mike and I met on St. Patrick’s Day, so even though I’m not Irish the holiday holds a special place in my heart. Especially when I can use colored marshmallows.

I needed a bag of “cereal marshmallows” for a project a while back, and since the smallest bag you can buy is a pound I had a LOT left over. So I took to Pinterest. And most recipes were either for some sort of rice krispies treat, bark or snack mix.
I’d already done the bark and you know how I feel about krispies treats. I thought about the snack mix but what I really wanted to do was bake the marshmallows into cookies.

I folded them into a simple slice and bake dough – and was already excited about the “terrazzo” effect – and popped them in the oven. Then this happened:

I had no idea that the marshmallows would turn from pale pastel to jewel-toned, but it was one of the happier accidents to happen in my kitchen. I had originally planned to just serve the cookies plain, but I was so inspired by the colors that I decided to sandwich them with a dyed-to-match filling!

How pretty are these???
So easy too. The cookie dough is super simple, and the filling is a sugar-fueled mix of marshmallow fluff and confectioner’s sugar.
Make these for your little leprechauns!

Lucky Charms Sandwich Cookies
For the cookies:
1 cup (2 sticks) unsalted butter, at room temperature
1/2 cup granulated sugar
1/4 cup brown sugar
1 teaspoon vanilla
2 1/4 cups flour
3/4 teaspoon kosher salt
1 cup cereal marshmallows
For the filling:
1 1/2 cups marshmallow fluff
2/3 cup unsalted butter, at room temperature
1 1/3 cup confectioner’s sugar
food coloring

Make the cookies: Beat the butter, both sugars and vanilla till light and fluffy. Scrape down the sides, add the flour and salt and beat again. Add the cereal marshmallows and beat for just a few seconds more. Divide the dough in half and roll each half into a log that is about 8 – 9″ long and about 2″ in diameter. Wrap each log in plastic wrap and freeze for at least 30 minutes (or up to 2 months in advance).

Pre-heat the oven to 350 degrees; line two baking sheets with parchment paper.

Slice each log into 1/2″ thick rounds and place about 1″ apart on your baking sheets. Bake till the edges are golden brown, about 12 – 15 minutes. Transfer to a wire rack to cool.

Make the filling: Beat the fluff and butter till light and fluffy. Scrape down the sides, add the confectioner’s sugar and beat again. Divide into as many bowls as you have food colors and tint each to your desired shade.

Spread or pipe the frosting onto the undersides of half the cookies; top with the remaining cookies, pressing gently to adhere.
