A box of gluten-free chocolate chip cookie mix gets two-thirds cup of chopped pecans folded in before the dough is shaped into 30 rounds and baked. While still warm from the oven, half a large marshmallow goes cut-side-down onto each cookie and the pan goes back in briefly until the marshmallows puff and soften. The chocolate frosting — semisweet chips melted with whipping cream, butter, vanilla, and powdered sugar — gets spooned over the top once the cookies cool. The layering makes them thick and holds up well at room temperature for a day.
