In a large bowl, stir together the sweetened condensed milk, vanilla extract, salt, and blue gel food coloring until smooth and evenly colored.

In a separate large bowl, beat the cold heavy whipping cream with a hand mixer or stand mixer until stiff peaks form, about 3 minutes.

Fold about 1 cup of whipped cream into the condensed milk mixture to lighten it. Add the remaining whipped cream and fold gently until mostly combined.

Fold in the chopped cookies just until evenly scattered through the blue base. Do not overmix or the whipped cream will lose volume.

Spread the mixture into a loaf pan or freezer-safe container. Sprinkle the reserved cookie pieces on top, cover tightly, and freeze for at least 6 hours or overnight.

Let the ice cream sit at room temperature for 5-10 minutes before scooping. Serve in cones or bowls with extra cookie crumbs if desired.
