In a large bowl, whisk together the sweetened condensed milk, cocoa powder, malted milk powder, sour cream, vanilla extract and salt, until well combined. The mixture will be thick.
In a separate bowl, whip the cream with an electric mixer until soft, fluffy peaks form. Add 1/3 of the whipped cream to the chocolate mixture, folding it in with a spatula to loosen up the chocolate mixture. Fold in the rest of the whipped cream until mostly combined.
Place the malted milk balls in a freezer bag and use a rolling pin or something heavy to gently crush the candy into chunks. Add the crushed candy to the ice cream (reserving 1/4 cup to sprinkle on top), and fold it in.
Spread the ice cream into a lidded, freezer safe container, and sprinkle with the rest of the crushed malted milk balls. Freeze for at least 8 hours, or overnight, until firm enough to scoop.
