To ensure an easy bite and avoid breaking, choose cookies that are just a little bit chewy.
To make assembly easier, spread vanilla ice cream on a baking sheet, freeze it, and then cut it to size.
To avoid the cookies melting the ice cream too soon, slightly chill them.
To keep sandwiches tidy and undamaged during assembly, wrap them in parchment paper.
After assembly, place the sandwiches in the freezer for 15 to 20 minutes to solidify and stop them from melting.
