Plastic wrap or parchment for lining
Instructions
Prepare:
Line a small pan or container with plastic wrap or parchment, leaving some overhang for easy removal. Lightly dust the work surface or a plate with cocoa powder for finishing.
Warm the condensed milk: Pour condensed milk into a small saucepan and warm over low–medium heat, stirring often. When bubbles begin to appear around the edges and the mixture is slightly thinned, remove from heat (do not boil vigorously).
Sift the cocoa: Sift the cocoa powder into a bowl to remove lumps. Add the cocoa to the warm condensed milk in 2–3 additions, mixing thoroughly after each addition until fully incorporated and smooth. The mixture should thicken into a stiff, glossy, frosting-like dough with an intense chocolate aroma.
Transfer and Chill:
Spread the mixture into the prepared pan, smoothing the top. If your pan is large, fill only halfway to get a thicker truffle block. Cover and refrigerate 2–3 hours (or until firm).
Shape:
Remove the chilled block using the overhanging wrap. Dust the top with extra cocoa powder. Cut into bite-sized pieces (or scoop and roll with lightly cocoa-dusted hands). If desired, gently shape each piece by pinching and rolling to make rounded truffles.
Finish and store:
Dust each truffle with more cocoa powder, tap off excess, and arrange on a plate. Store in an airtight container in the refrigerator for up to 1 week (or freeze for longer storage).
Notes
Use a good-quality unsweetened cocoa powder for best chocolate flavor.
If the mixture is too soft after chilling, refrigerate longer. If too firm to shape, let sit a few minutes at room temperature.
For variation: roll truffles in chopped nuts, shredded coconut, or melted chocolate (if you want more than two ingredients).
