    1. Combine the butter and sugars in a stand mixer with a paddle attachment.
    2. Cream together on medium-high for 2 to 3 minutes.
    3. Scrape the sides of the bowl, add the egg and vanilla, and beat for 7 to 8 minutes.
    4. Reduce the mixer speed to low and add the flour, baking powder, baking soda, and salt. Mix just until the dough comes together - no longer than a minute.

    1. Divide dough into ¼ c. balls, stuff with 2 or 3 mini marshmallows, and place balls on a parchment-lined cookie sheet. Refrigerate for at least an hour, or place in the freezer for 30-45 minutes. (This dough must be chilled!)
    2. Heat the oven to 365°f
    3. Re-arrange the dough balls a minimum of 4 inches apart on a parchment - or Silpat-lined cookie sheet and bake for 11-16 minutes (check the cookies at 11 minutes, mine took 12!) The cookies will puff, crackle, and spread.
    4. Cool the cookies completely on cookie sheets before transferring them to a plate. Store in an airtight container, if you have any left to store.

    They are not hard to make, but they do take some time. It's worth it! Also, you can totally freeze some of the dough and pull it out on another day or give them away to friends or neighbors.

      These were an absolute win with my kids. They especially loved the marshmallows just baked right on top of the cookies.

      I made this with a few substitutions, did regular corn flakes instead of frosted and did a little less m&m’s and marshmallows than recommended . That being said, it was delicious! I think it would be too sweet otherwise. Also, I halved the recipe and felt like the flour didn’t mix that well using a hand mixer in a minute as recommended, I wish I had mixed just a little longer.
