Warm the milk, salt, sugar and 1 c. of cream in a medium sauce pan. Scrape the seeds from the vanilla bean or add the ground vanilla bean to the warm milk. Cover and keep on low heat (just enough to keep warm) for 30 minutes.
Pour the remaining 1 c. of cream into a large mixing bowl and place a mesh sieve on top.
In a separate medium mixing bowl, whisk together the egg yolks. Slowly pour the warm milk mixture into the yolks, whisking constantly. After combined, scrape the mixture back into the saucepan and return to medium heat. Using a heatproof spatula, scrape the bottom as you stir, until the mixture coats the bottom of the spatula and/or reaches 170 degrees.
Pour the heated mixture through the strainer and into the cream. Add the vanilla extract.
Place over an ice bath to cool, then place in refrigerator for 30 minutes until chilled throughout.
Freeze according to manufacturer's instructions. When finished churning, stir in cookies with spatula.
Place in a air-tight freezer safe container and freeze for at least 4 hours.
