A completely from-scratch dessert featuring homemade oat milk ice cream sandwiched between freshly baked oatmeal raisin cookies. The no-churn ice cream is created by blending rolled oats and dates into a creamy ‘oat milk’ base, which is then lightened with sweetened condensed milk and freshly whipped cream. The cookies are a classic oatmeal raisin variety, providing a chewy texture that complements the creamy frozen filling.
