Chocolate Mocha Crunch Pie

This is a coffee lover’s pie through and through, a French silk-style chocolate filling spiked with instant coffee and piled into a crunchy nut crust.

The texture is the whole game. You beat each egg into the chocolate-butter base for a full five minutes, which whips in enough air to turn the filling glossy, mousse-light, and almost weightless on the tongue. Skimp on the beating and it sets dense and grainy instead.

The crust earns the word crunch in its name. Crumbled pastry gets tossed with grated chocolate and chopped walnuts, pressed thin, and baked until crisp, a far cry from a soft graham base.

A long chill firms the filling, then it’s finished with billows of coffee-scented whipped cream just before serving.

Pro Tips

• Beat the full five minutes per egg. That patience is what gives French silk its signature airy, silky body.
• Cool the melted chocolate before it joins the butter, or the heat will weep oil out of the creamed base.
• Chill the bowl and beaters before whipping the cream, and stop at soft peaks so it stays plush, not buttery.
• The filling uses uncooked eggs, so reach for pasteurized eggs if you’re serving anyone vulnerable.

Variations

• Swap walnuts for toasted pecans or hazelnuts in the crust for a different crunch.
• Bump up the coffee for a stronger espresso edge, or fold a tablespoon of coffee liqueur into the whipped cream.
