Peanut Protein Bar with Cocoa Shell

Headnote

This bar is built for clean structure and exact balance: a supple protein matrix, a restrained peanut core, and a thin cocoa finish that gives the bar its identity. The sweetness is controlled, the texture is dense but not heavy, and the finish should remain smooth rather than brittle. It is conceived as a compact confection with the discipline of a pastry and the clarity of a sports bar.

Ingredients

Protein base

Milk protein, 18 g

Collagen hydrolysate, 6 g

Sweetener, 5 g

Milk powder, 4 g

Salt, 0.3 g

Glycerol, 3 g

Emulsifier, 0.7 g

Peanut, 9 g, finely chopped

Soy crisp, 4 g

Cocoa coating

Cocoa butter, 2 g

Palm kernel oil, 1.5 g

Cocoa mass, 1.5 g

Method

1. Line the mold with parchment if needed and set it aside. In a small bowl, combine the milk protein, collagen hydrolysate, sweetener, milk powder, salt, and emulsifier. Mix thoroughly so the dry blend is uniform and free of streaks.

2. Add the glycerol and work it into the dry ingredients with a spatula until a firm, cohesive paste forms. The mixture should hold together when pressed and feel smooth, not powdery.

3. Fold in the chopped peanut and soy crisp just until evenly distributed. Do not crush the crisp; it should remain distinct for a light, brittle bite.

4. Press the mixture firmly into the mold in an even layer. Compress it with steady pressure so the surface becomes level and compact. Chill for 10 minutes, just until the bar is set enough to unmold cleanly.

5. Combine the cocoa butter, palm kernel oil, and cocoa mass in a small heatproof bowl set over a pan of barely simmering water. Stir until fully melted and glossy, then remove from the heat. The coating should be fluid, warm, and perfectly smooth.

6. Unmold the bar and coat it evenly with the cocoa mixture, using a spoon or the edge of the bowl to create a thin, complete shell. Let the excess fall away. Set the bar on parchment and allow the coating to firm at room temperature for 10 minutes, until the surface is dry to the touch and lightly snappy.

Plating and serving

Serve the bar whole, centered on a small plate or wrapped with precision. The exterior should be smooth and dark, with a clean cut revealing a dense, peanut-studded interior. The final bite must move from a thin cocoa shell to a yielding protein center with crisp interruption.

Professional notes

The bar depends on compression; insufficient pressure will produce a crumbly interior.

Keep the coating thin. A heavy shell will obscure the intended texture and make the bar feel clumsy.

The soy crisp should remain intact to preserve contrast against the dense protein matrix.
