One and a half cups white sugar
Three egg yolks, beaten
Half a cup unsweetened cocoa powder
Three tablespoons cornstarch
Half a teaspoon salt
Three cups whole milk
One tablespoon butter
One and a half teaspoons vanilla extract
Method for the filling
In a large saucepan, whisk together the sugar and egg yolks until pale and smooth. Gradually add the cocoa powder, cornstarch, and salt, whisking thoroughly to eliminate any lumps. Slowly pour in the milk while continuing to whisk, creating a uniform mixture.
Place the saucepan over medium heat and stir continuously. As the mixture warms, it will begin to thicken. Continue stirring until it reaches a custard like consistency and starts to bubble gently. This process requires patience and constant attention to prevent scorching.
Once thickened, remove from heat and immediately stir in the butter and vanilla extract. The butter adds richness while the vanilla deepens the overall flavor. Allow the cream to cool slightly before pouring it evenly over the prepared crust. Smooth the surface and refrigerate for two to four hours, or until the filling is fully set and firm.
For the topping with chocolate ganache and cream
Two hundred grams dark chocolate, finely chopped
Half a cup heavy cream for the ganache
One cup heavy cream for whipping
Two tablespoons icing sugar
A small pinch of vanilla extract
Method for the topping
Heat the half cup of heavy cream until just beginning to simmer. Pour it over the chopped dark chocolate and let it stand for one minute. Stir gently until the mixture becomes smooth, glossy, and fully blended. Pour the warm ganache over the chilled filling and spread evenly across the surface. Allow it to cool until set.
In a separate bowl, whip the remaining one cup of heavy cream with the icing sugar and vanilla extract until soft peaks form. Spoon or pipe the whipped cream over the ganache layer. For an elegant finish, decorate with chocolate shavings or a light dusting of cocoa.
This dessert requires about one hour of preparation time plus chilling time, but the result is a beautifully layered, silky chocolate tart that is deeply satisfying and unforgettable.
