In a medium bowl, combine all ingredients except for the Oreos and stir until all sugar is dissolved and fully combined.
1 1/2 cups heavy cream, 3/4 cup coconut milk, 3/4 cup granulated sugar, 1 Tablespoon pure vanilla extract
Cover with plastic wrap and place bowl in the fridge for 30 minutes to an hour to let it thoroughly chill.
Place Oreos in a heavy-duty plastic baggie and crush with a rolling pin. Don't obsess over making them all uniform - having big chunks isn't bad!
8-10 Oreo cookies
Pour batter into ice cream maker and prepare according to manufacturers directions (usually 25-30 minutes of churning). During the last 5 minutes, add in your crushed Oreos.
Note: The Oreos really bulk things up, so keep an eye on it so it doesn't overflow on you!
Store in freezer-safe container and freeze for a couple hours if you want it to be soft-serve texture (or overnight, if you want to eat it after it's hardened). Scoop it into a bowl or a waffle cone and enjoy!
