Method
Preparation
Preheat your oven to 350°F (175°C). Grease a mini tartlet pan or line it with parchment paper to ensure easy removal after baking.
Whisk together the flour, cocoa powder, and powdered sugar in a large bowl.
Incorporate the cold, cubed butter into your dry ingredients using a pastry cutter or your fingers.
Add the egg yolk to the mixture and stir until combined. If the dough feels too crumbly, add cold water.
Press the dough into small portions in the tartlet pan and prick the bottom with a fork.
Bake the tart shells for 10-12 minutes or until set. Let them cool slightly before filling.
Filling
Heat the heavy cream, granulated sugar, and butter in a saucepan over medium heat until hot.
Mix in the chopped chocolate and let it sit for one minute, then stir until smooth.
Whisk together the eggs, vanilla extract, and salt in a separate bowl. Gradually add the chocolate mixture.
Pour the chocolate fudge filling into the cooled tart shells until about 3/4 full.
Return the tartlets to the oven and bake for an additional 10-12 minutes until the filling is just set.
Cool the tartlets completely in the pan before transferring them to a wire rack.
Top with powdered sugar or whipped cream and chocolate shavings before serving.
Serve chilled or at room temperature.
Notes
Tip: Garnish with fresh raspberries for extra flavor.
