Headnote

This bar is built for clean structure: a dense, supple interior, a restrained sweetness, and a crisp chocolate shell. The peanut character is carried through the center, then sharpened by cocoa and a firm coating that sets with a precise snap. It should eat as a finished confection, not as a compromise.

Ingredients

Protein center

18 g milk protein

8 g collagen hydrolysate

5 g soy protein isolate

4 g peanut, finely ground

3 g sweetener

2 g glycerol

1 g palm kernel oil, melted

Chocolate coating

6 g chocolate coating

4 g cocoa butter

2 g cocoa mass

Finish

2 g peanut, finely chopped

Method

1. Line the mold with parchment if needed. In a small bowl, combine the milk protein, collagen hydrolysate, soy protein isolate, ground peanut, and sweetener. Mix thoroughly until the powders are evenly distributed and the mixture appears uniform.

2. Add the glycerol and melted palm kernel oil. Work the mixture with a spatula for 1 to 2 minutes until it gathers into a compact, pliable mass. It should hold together when pressed and feel smooth rather than crumbly.

3. Press the center mixture firmly into the mold, shaping it into a neat bar. Compress it evenly from end to end so there are no voids. Chill for 5 minutes, just until the surface firms.

4. Melt the chocolate coating, cocoa butter, and cocoa mass together in a heatproof bowl set over gently simmering water. Stir until fully smooth and fluid, then remove from the heat. The coating should be glossy and pourable, with no visible particles.

5. Unmold the chilled bar and place it on parchment. Coat it evenly with the melted chocolate mixture, turning once to cover all sides. Allow the excess to drain briefly, then smooth the surface with an offset spatula.

6. Scatter the chopped peanut over the coating before it sets. Leave the bar at cool room temperature for 10 minutes, or until the shell is firm and the surface has a clean, dry finish.

Plating and serving

Place the bar slightly off-center on a narrow plate or parchment-lined tray. Serve at cool room temperature, when the shell gives a distinct snap and the center remains dense, cohesive, and softly yielding.

Professional notes

The center must be compressed firmly; weak packing produces a sandy break.

Keep the coating warm enough to flow, but not hot enough to dull the finish.

The bar is correct when the exterior is crisp and the interior slices cleanly without crumbling.
