Step 1: Prepare the Crust
In a large bowl, whisk together flour, cocoa powder, sugar, and salt.
Add cold butter and mix until the mixture resembles coarse crumbs.
Stir in egg yolk, vanilla extract, and cold water until a dough forms.
Press the dough evenly into a 9-inch tart pan and refrigerate for 30 minutes.
Preheat oven to 350°F (175°C). Bake the crust for 12-15 minutes, then set aside to cool.
Step 2: Make the Chocolate Filling
In a saucepan over medium heat, warm the heavy cream until just simmering.
Remove from heat and add the chopped dark chocolate, stirring until smooth.
In a separate bowl, whisk together sugar, eggs, vanilla extract, and salt.
Slowly pour the chocolate mixture into the egg mixture, whisking constantly.
Pour the filling into the cooled tart crust.
Step 3: Prepare the Crumble Topping
In a bowl, mix flour, cocoa powder, and sugar.
Cut in cold butter until the mixture forms small crumbs.
Sprinkle the crumble evenly over the chocolate filling.
Step 4: Bake the Tart
Bake at 350°F (175°C) for 25-30 minutes, or until the center is set.
Let cool completely before serving.
