Making a homemade ice cream sandwich sounds easy, right? What could be so difficult about putting a scoop of ice cream between two cookies and smashing them into the form of a sandwich? Turns out there's a lot of small things to consider in order to get the perfect firmness of ice cream with the toothsome texture of cookie (read: not rock solid). Luckily for us, Cook's Illustrated Senior Editor Lan Lam spent a lot of time in the test kitchen at America's Test Kitchen perfecting a cookie recipe that lays the foundation for the most wonderful homemade ice cream sandwich. She gave the scoop to our Managing Producer Sally Swift and shared the recipe for Chocolate Chip Cookie Ice Cream Sandwiches. Listen to their conversation using the audio player above and read Lan Lam's full Cook's Illustrated article here. All photos: America's Test Kitchen

Shaping cookiedsGetting the size and shape of the cookie is key to a perfect ice cream sandwich. Lan tests ways to make the cookies thin and even, including pressing the dough mounds before baking.

Shaping the ice cream sandwich1/4-inch thick cookies and 1-inch of ice cream makes for a sandwich that is substantial but not too tall, the perfect 2:1 ratio of ice cream to cookies.
