Place the sliced bananas in a freezer-safe container and freeze for at least 2 hours until solid.

In a blender, combine the frozen bananas, coconut milk, honey, and vanilla extract.

Blend until smooth and creamy, scraping down the sides as needed.

Pour the mixture into an ice cream maker and churn according to the manufacturer's instructions.

Transfer the churned ice cream to a freezer-safe container and freeze for an additional 1-2 hours to firm up.
