Magical Marshmallow Surprise Cookies made easy with sugar cookie mix, butter, an egg & rainbow twist marshmallows and festive sprinkles for a delightful, tasty treat!
Preheat oven to 350°F. Line a baking sheet with parchment paper.
Place the 12 marshmallow twists in the freezer to firm up a bit while you make the cookies.
In a large bowl combine the sugar cookie mix, butter, and egg. Mix until a soft dough forms.
Divide the dough into 12 portions, weighing just under 2 ounces each, and roll into balls. Make an indention with your thumb in the center of each dough ball. (This will help when we later place our marshmallows in the centers.)
Place 6 dough balls about 3 inches apart on a baking sheet. Bake for 10 minutes- the cookies will be underbaked still. Remove baking sheet from oven and carefully press 1 marshmallow twist into the center of each cookie. Marshmallows should go all the way through the cookie, hitting the baking sheet.
Return cookies to oven and bake for another 2-3 minutes, or until the marshmallows are puffy and cookies are very lightly golden. (Cookies will continue to set up after they’re removed from the oven. Avoid overbaking to prevent dry cookies. )
Remove baking sheet from the oven and allow cookies to cool for 3 minutes. Use the back of a spatula to gently press the marshmallow level with the tops of the cookies. Gently transfer to a wire rack to cool for at least 30 minutes before frosting.
Once cooled, frost cookies with about 2 tablespoons of frosting, covering up the magical marshmallow. Top with sprinkles. Serve & enjoy!
