4.4oz (125g) semisweet chocolate, melted and cooled
1 14-ounce can (397g) sweetened condensed milk
½ cup (2oz/60g) unsweetened cocoa powder (I use Dutch-processed)
2 cups (500ml) heavy whipping cream (or whipping cream with at least 35% fat)
3.2 oz / 90g (about 1½ cups) mini marshmallows + a few extra for garnish
Instructions
Pull the marshmallows apart if there are any stuck together. Set aside.
Whip the heavy cream to stiff peaks. Put it in the refrigerator while moving on to the next step.
In a large bowl, mix the cooled melted chocolate, cocoa powder, and sweetened condensed milk with a hand mixer until combined.
Fold in the whipped cream and the mini marshmallows. Make sure everything is fully incorporated and there are no more white streaks from the whipped cream.
Then transfer the mixture to a freezer-safe container. If you want, press some more marshmallows on the surface.
Cover the surface with plastic wrap and then some foil and freeze for 8 hours (or overnight).
