M&Ms Sandwich Cookies

 If you haven’t noticed, I love sandwich cookies. This blog has existed for eight months, and I already have six sandwich cookie recipes in my recipe index. I mean, cookies and frosting together–does a more perfect dessert even exist?! 

Today’s sandwich cookies are my version of a favorite treat from my teenage years. Back then, I was on the high school dance team. Once classes were over for the day, I’d have thirty minutes to change and eat something before practice. Usually the whole team would go for some sort of fast food (ah, teenage metabolism), but occasionally, when everyone was attending tutorials or some other after-school program, I’d zip over to Ridgmar Mall, run to the cookie kiosk, and grab one or two (okay, okay, three!) miniature M&Ms sandwich cookies before driving back to school to dance off all the calories.

To this day, I get nostalgic for those soft cookies, M&Ms, and creamy vanilla filling. But I can’t remember the last time I was in a mall (one of the advantages of living in New York City). And as I always have fresh baked goods at home, I no longer stop for mass-produced treats. 

These days, if I want a few M&Ms Sandwich Cookies, I make them myself. They’re so much better than anything you could get at a mall. Soft, chewy cookies speckled with colorful milk chocolate M&Ms and sandwiched together with a smooth vanilla filling?! Yes. I’ll take three.

Most of my sandwich cookie recipes make five or six dozen very small cookies–far more than anyone really needs. This recipe makes a much more manageable two dozen sandwich cookies. If you’d like more, this recipe doubles very well.

Also, these cookies are slightly larger than my regular sandwich cookies. Where all of my other sandwich cookie recipes require you to scoop dough by the teaspoon, the cookies in this recipe are each made with 1/2 tablespoon (1 1/2 teaspoons) of dough. The larger scoops cut down on the time spent rolling dough and also allow for more M&Ms in every bite! 

I love working with M&Ms for holidays. There’s a perfect color combination for every occasion–red and green for Christmas, orange and black for Halloween, pastels for Easter. Since the Fourth of July is coming up next week, I went with the red, white, and blue variety for this batch! I think they’re pretty cute 😊 No matter which holiday you’re making these for (even if it’s just that it’s the end of a long week), I know these M&Ms Sandwich Cookies will be a hit!

M&Ms Sandwich Cookies
makes 2 dozen sandwich cookies

1 1/2 cups all-purpose flour
1 teaspoon cornstarch
1/2 teaspoon cream of tartar*
1/2 teaspoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon Kosher or sea salt
1/2 cup (1 stick) unsalted butter, softened to room temperature
1/2 cup granulated sugar
1/4 cup light brown sugar
1 large egg, room temperature
1 teaspoon pure vanilla extract
1 cup M&Ms milk chocolate candies

Filling:
1/2 cup shortening (or room temperature unsalted butter)
2 1/2-3 cups confectioner’s sugar
pinch of Kosher or sea salt
2 teaspoons pure vanilla extract
1-2 tablespoons heavy cream

In a medium-large mixing bowl, whisk together flour, cornstarch, cream of tartar, baking powder, baking soda, and salt. Set aside.

In a large mixing bowl, use an electric mixer to beat butter until light and fluffy, about two minutes. Beat in granulated and light brown sugars, followed by egg and vanilla. Mix in dry ingredients in two installments, combining completely after each addition. With the mixer on low, add in M&Ms and mix for 10-15 seconds until they are evenly dispersed. Cover and chill dough for 90 minutes, or up to three days.

Preheat oven to 350F. Line two baking sheets with parchment.

Scoop chilled dough by the 1/2 tablespoon (1 1/2 teaspoons) and roll into balls. Set dough balls about two inches apart on prepared pans. Bake 7-8 minutes, until the tops are no longer shiny. Let cookies cool on pans for five minutes before removing to a rack to cool completely. Repeat with any remaining dough.

Make the filling. In a large mixing bowl, use an electric mixer to beat shortening (or butter) until fluffy. Beat in 2 1/2 cups confectioner’s sugar and salt. Mix in vanilla and 1 tablespoon heavy cream. If filling is too thin, add more confectioner’s sugar. If it’s too thin, add an extra tablespoon of heavy cream. If you would like to pipe the filling, spoon it into a piping bag and snip off a corner.

There are two options for filling:

1. To assemble a sandwich cookie by piping, apply filling by pipe a circle in the middle of the underside of one cookie, leaving about 1/4″ around the edge. Top with a second plain cookie, with the underside filling-side-in. Repeat until all cookies have been used.

2. To assemble a sandwich cookie by spreading, use an offset frosting knife to spread 1/2-1 teaspoon on the underside of one cookie. Top with a second plain cookie, with the underside filling-side-in. Repeat until all cookies have been used.

M&Ms Sandwich Cookies will keep in an airtight container at room temperature for up to a week.

Note:

There is no substitute for cream of tartar in this recipe.
