Creating Chocolate Salted Caramel Tart is easier than you might think! Follow these simple steps:

**For the Crust:**

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Make the Dough: In a food processor, combine the flour, cocoa powder, sugar, and salt. Add the cold butter and pulse until the mixture resembles coarse crumbs.
3. Add Egg Yolk: Add the egg yolk and a tablespoon of cold water; pulse until the dough clumps together. Add more water as needed.
4. Roll Out: Turn the dough onto a lightly floured surface and form it into a disc. Roll out to fit a 9-inch tart pan.
5. Blind Bake: Press the dough into the tart pan, trim the excess, and prick the bottom with a fork. Place parchment paper on top and fill with pie weights or dried beans.
6. Bake: Bake in the preheated oven for about 15-20 minutes. Remove the weights and parchment and bake for an additional 5 minutes until firm. Let it cool.

**For the Chocolate Ganache:**

7. Heat the Cream: In a saucepan, heat the heavy cream over medium heat until it begins to steam, but do not let it boil.
8. Combine with Chocolate: Pour the hot cream over the chopped chocolate in a bowl. Let it sit for 5 minutes, then stir until smooth.
9. Add Vanilla: Stir in the vanilla extract. Pour the ganache into the cooled tart shell, spreading it evenly. Refrigerate until set, about 30 minutes.

**For the Salted Caramel:**

10. Make Caramel: In a saucepan over medium heat, melt the granulated sugar, stirring constantly until it turns a deep amber color.
11. Add Butter: Remove from heat and immediately whisk in the cubed butter until melted and smooth.
12. Add Cream: Gradually add the heavy cream while whisking until combined. Stir in sea salt to taste.
13. Cool Caramel: Let the caramel cool for a few minutes before pouring it over the set ganache in the tart shell.

**Final Assembly:**

14. Chill: Place the tart back in the refrigerator and allow the caramel to set for at least 1 hour.
15. Garnish: Before serving, sprinkle additional sea salt on top for an extra flavor kick.

Each step brings you closer to the most delightful Chocolate Salted Caramel Tart, a true centerpiece for any dessert table.
