Once the cookies are baked, prepare the ice cream.
Add the oat cream to a saucepan on medium heat and mix in the corn starch. Stir and cook. Let simmer until the mixture has thickened.
Mix in the sugar, vanilla and salt until completely dissolved and combined.
Mix the cashews together to a silky smooth cashew cream in a blender.
Mix the cashews in with the oat mixture. Let the mixture cool before pouring in an ice cream machine.
Pour the mixture into an ice cream machine and let it churn until the machine doesn't mix anymore.
When the ice cream is ready, take a scoop of ice cream and sandwich between two cookies. Roll the ice cream in chocolate chips if you desire or eat as is! Enjoy!!
