First, a little piece of history: despite its name, the French silk pie came to be in 1950s America. And it's easy to see why the pie, in all its forms, has become such a beloved dessert today. Perfect for a romantic night in or small-batch treat to bookend your workweek with, these individual French silk pie cups stay true to the rich, chocolaty, mousse-like texture they're known for while managing to be low-carb and keto-friendly.

To make the crust

1. In a small bowl, whisk the almond flour, cocoa powder, and sweetener together. Stir in the melted butter until the mixture resembles coarse crumbs.
2. Divide crumbs between two small dessert cups or ramekins and press firmly into the bottom. Set aside.

To make the filling

1. In a heatproof bowl set over a pot of barely simmering water, melt the chocolate, stirring until smooth. Set aside to cool for at least 5 minutes.
2. In a large bowl, beat the butter and the sweetener together with an electric mixer until well combined. Slowly add the melted chocolate, beating until thoroughly combined. Beat in the vanilla extract and salt.
3. Add the egg and beat on medium for about 5 minutes, until the mixture is lightened and very smooth.
4. Divide the mixture between the two dessert cups. Refrigerate one hour to set.

To make the decoration

1. Garnish with a dollop of lightly sweetened whipped cream if desired.
2. To make the chocolate hearts, simply melt about 1/4 ounce sugar-free dark chocolate (not unsweetened chocolate). Spoon into a Ziploc bag and snip the very tip from one of the corners. Pipe into hearts on waxed paper and refrigerate until set. Once set, carefully peel hearts off waxed paper and garnish cups or plates as desired.
