In the bowl of a food processor, add chopped cookies and process. With the motor running, add ⅓ cup coconut milk. Add more, as needed, until the spread is smooth and thick. Gradually pulse in up to 2 teaspoons powdered sugar (taste as you go, and stop when sweet enough!)
Transfer the cookie butter to a jar, and refrigerate for up to two weeks.
Notes
