Sandwich cookies have a special place in my heart. Sure regular cookies are great too, but with sandwich cookies, you get two cookies plus filling to hold it all together! And if you’re like me, twisting off one side and eating the frosting filling first is half the fun. These mini sandwich cookies I made recently fit that bill. They are crisp and chocolaty, paying homage to Oreo™ cookies, but they have the best kind of frosting in the middle: Rainbow Chip! For this recipe, you only need a handful of ingredients: Betty Crocker sugar cookie mix, three tablespoons of cocoa powder, a melted stick of butter, an egg, and Rainbow Chip frosting. First, preheat your oven to 350°F and line two cookie sheets with parchment paper and set aside. Make the sugar cookie dough next by combining the cookie mix with the cocoa powder in a medium bowl. Whisk to combine. Add the melted butter and one egg and continue mixing until a soft dough forms. Next, roll out the dough on a floured surface until it’s ¼-inch thick. Use a 1 ½-inch round cookie cutter to stamp out circles for the cookie sandwiches and then place them 1-inch apart on cookie sheets. (Alternatively, you can use an upside-down shot glass to cut out the circles too.) If the dough is too soft and difficult to work with, stick it in the freezer for around 5 minutes or so to firm it up a bit. Bake the cookies for 7 to 9 minutes, and transfer to a wire rack to cool completely. Don’t start frosting them until they’re completely cooled! They won’t crisp up properly if you do. Now comes the fun part! Use a butter knife to spread a dollop of Rainbow Chip frosting on the flat side of one cookie. It doesn’t have to be neat (because keep in mind, you’ll be covering it with another cookie!), and you can add as much as you want! Take another cookie and press the flat side of it on top of the frosting. The frosting should spread out from the pressure of the top cookie and fill out the bottom cookie perfectly, creating an awesome sandwich cookie! If your frosting oozes out, just use less the next time. Or lick off any extra! That’s cool too.
