Soft, sliceable chocolate candy made with whole milk, unsweetened cocoa powder, and cornstarch. Cook until thick and glossy, chill for an hour, then cut into pieces and coat with cocoa.
Pour 240 ml whole milk into a saucepan, add 3 tablespoons unsweetened cocoa powder, and whisk until the cocoa is fully blended into the milk.
Add 200 g granulated sugar and 60 g cornstarch Whisk until smooth, making sure there are no visible lumps before heating.
Place the saucepan over low heat and cook, stirring continuously, for about 10 minutes, until the mixture thickens to a pudding-like consistency.
Add ¼ teaspoon salt and 10 g unsalted butter Stir until the butter has melted and is fully incorporated.
Continue cooking over low heat for about 20 minutes, stirring constantly, until the mixture becomes very thick and glossy and pulls away from the sides of the pan.
Transfer the mixture to a tray lined with parchment paper. Spread into an even layer about ½ inch (1.3 cm) thick.
Refrigerate for 1 hour, until firm enough to cut cleanly. There is no separate room-temperature cooling step.
Remove the set candy from the parchment and cut into 21 pieces. Place 2 tablespoons unsweetened cocoa powder in a shallow dish and lightly coat the pieces, shaking off any excess before serving.
Notes
Soft texture: These candies have a soft, sliceable center rather than the firm snap of a chocolate bar. Serve chilled for a firmer bite.Measure cocoa separately: Use 3 tablespoons of unsweetened cocoa powder in the mixture and reserve the remaining 2 tablespoons for coating after chilling and cutting.Coating: Keep the cocoa coating light so it complements the candy without making the outside too bitter.Storage: Keep in an airtight container in the refrigerator for up to 4 days. Let the pieces sit out for a few minutes before serving if you prefer a softer texture.
