Start by making the caramel.

In a medium sized pot combine the water and Swerve.

Set over medium heat and bring to a simmer.

Continue to simmer for 5-7 minutes until it turns golden and has reduced.

Whisk in the butter, cream, vanilla, and salt.

If its too thin keep simmering until it is slightly thick.

Note: it will thicken as it cools as well.

 For the ice cream, combine all ingredients in a blender and blend until smooth.

Pour the mixture into an ice cream maker ...

 ...

and churn according to the manufacturer's directions.

Once its done churning pour into a quart size container and swirl in the caramel using a knife to swirl it through the layers.

Freeze 3-4 hours.
