In a large mixing bowl, combine the sweetened condensed milk, vanilla extract, and kosher salt. Stir until completely combined.
In a separate bowl, whip the heavy cream to stiff peaks using a hand mixer or stand mixer.
Gently fold the whipped cream into the condensed milk mixture, being careful not to deflate the whipped cream.
In a 8X8 pan or a freezer safe container, spread ⅓ of the ice cream base evenly across the bottom.
Drizzle ⅓ of the caramel sauce and chocolate ganache over the ice cream, then sprinkle ⅓ of the pecans.
Repeat this layering process two more times, finishing with a drizzle of caramel sauce, chocolate ganache, and a sprinkle of pecans on top.
Cover the container tightly with plastic wrap or a lid. Freeze for at least 6 hours or overnight until firm. Top with turtle candies for a fun touch if desired!!
To store the ice cream, press a layer of plastic wrap or parchment paper directly onto the surface to prevent freezer burn for up to 1 month.
