In a high-speed blender, combine the almond milk, peanut butter, softened cream cheese, stevia, and vanilla extract.
Blend on high for 2-3 minutes, or until the mixture is completely smooth and silky. Scrape down the sides as needed.
Taste and adjust sweetness if desired.
Pour the mixture into your ice cream maker and churn according to the manufacturer's directions, typically for about 20-25 minutes, until it reaches a soft-serve consistency.
Transfer the churned ice cream to a freezer-safe container, cover, and freeze for at least 1-2 hours to firm up before serving.
Add one tablespoon of vodka or MCT oil to the mixture before churning. This lowers the freezing point and keeps the ice cream scoopable straight from the freezer.
