To prepare the ice cream:

1. Line a 9×13” or jelly roll pan with a large sheet of aluminum foil. Be sure the foil extends just beyond the sides of the pan for easy removal. Set aside.
2. In a medium-sized bowl, stir together the fluff and condensed milk. Set aside.
3. In a large bowl or the bowl of a stand mixer, whip the cream on medium speed until it thickens to fluffy, stiff peaks. Fold in the fluff mixture, being careful to not overwork, and spread it into the prepared pan. Freeze until solid, at least 6 hours but preferably overnight.

To prepare the cookies:

1. Preheat the oven to 350 degrees Fahrenheit and line 2 sheet pans with parchment paper.
2. In a large bowl or the bowl of a stand mixer, cream the butter, brown sugar, and sugar until smooth and combined, about 1-2 minutes. Add the egg, molasses, and vanilla and stir to combined. Scrape the sides of the bowl and add the remaining ingredients. Stir on low just until well-combined.
3. Use a medium cookie scoop to spoon 1-1/2 tablespoon sized rounds of dough 2” apart on the prepared cookie sheets. Bake one at a time in the preheated for about 10 minutes or until the edges are set and almost turning golden. The center of the cookie will still look wet. Remove from oven and allow to cool completely. For easy assembly of the sandwiches, I like to freeze the cookies, but this is totally optional.

To assemble the sandwiches:

1. Use a large round cookie cutter or the lip of a wide-mouth mason jar to cut out rounds of ice cream. Place in between two cookies and refreeze the sandwiches quickly. You can save the leftover edges of the ice cream in a sealable container or freezer-safe bowl. Keep the sandwiches covered while in the freezer to protect their taste.
