Prepare the Chocolate Base: Whisk the cocoa and hot water together to bloom the cocoa, creating a smooth chocolate syrup. Next, whisk in the sweetened condensed milk to slightly cool the mixture. Finally, add the cream, milk, and salt, mixing until the mixture turns a medium chocolate brown.
Freeze the Mixture: Pour the mixture into your Ninja Creami tub and freeze overnight or for up to 24 hours, leaving the lid off.
Process in the Ninja Creami: When ready, process the mixture using the "ice cream" setting on your Ninja Creami. This recipe usually reaches the perfect consistency after just one spin.
Serve and Store: Serve your rich chocolate ice cream immediately. If you have leftovers, store them in the freezer with the lid on. This ice cream doesn’t usually need re-processing; just let it soften slightly on the counter before serving.
