Begin by breaking the high-quality dark chocolate into small pieces. Melt it gently using a double boiler or in the microwave, ensuring it doesn’t burn. Stir it until smooth and let it cool slightly.
In a mixing bowl, pour in the 500 ml of fresh double cream. Using a whisk, beat the cream until soft peaks form. This process usually takes about 3-5 minutes of vigorous whisking.
In another bowl, mix the condensed milk, unsweetened cocoa powder, melted chocolate, and vanilla extract. Stir until everything is well combined and smooth.
Carefully fold the whipped cream into the chocolate mixture using a spatula. Start by adding a small amount of whipped cream to lighten the chocolate mixture, then gently fold in the rest until no white streaks remain.
Finally, fold in the chocolate chips for an extra burst of flavor and texture throughout your gelato.
Transfer the gelato mixture into a freezer-safe container. Smooth the top with a spatula, cover it tightly, and place it in the freezer. Allow it to freeze for at least 6 hours, or overnight for the best texture.
