I think you could do a ton of great variations on this recipe. Like a crushed gingersnap base with chocolate ice cream and butterscotch chips instead of chocolate chips. Or a Biscoff cookie base with coffee ice cream. Or a graham cracker base with quality, real vanilla ice cream.
But below is Grandma Piper’s original recipe, with some notes from my friend Sarajane Blair. Grandma preferred mint chocolate chip.
This is super simple but takes a lot of freezing, so plan to make it at least a day in advance. It’s easiest if you give it a few days and do most of the freezer time overnight.
