0.5cupsunsalted butter, softened to room temperature
1largeegg yolk
1tablespooncold water
1cupsgranulated sugar
6tablespoonsunsalted butter, cut into small cubes
0.5cupsheavy cream (at room temperature)
1teaspoonsea salt
1cupssemi-sweet chocolate chips
0.5cupsheavy cream
Instructions
Prepare the crust: In a medium mixing bowl, combine the all-purpose flour, unsweetened cocoa powder, and powdered sugar. Mix until well incorporated. Add the softened butter and use a fork or pastry cutter to blend until the mixture resembles coarse crumbs.
Incorporate the egg yolk and add the cold water gradually, mixing until a smooth dough forms. If the dough is too crumbly, add a little more cold water, one teaspoon at a time.
Press the dough evenly into the bottom and up the sides of a 9-inch tart pan. Use your fingers or the bottom of a measuring cup to smooth it out. Prick the bottom of the crust with a fork to prevent bubbling, then refrigerate for 30 minutes to firm up.
Preheat the oven to 350°F (175°C). Once the crust is chilled, bake it for 15 minutes. Remove from the oven and allow to cool completely in the pan.
Make the salted caramel: In a medium saucepan over medium heat, add the granulated sugar. Cook, stirring constantly, until the sugar melts and turns a deep amber color. Stay vigilant during this step, as sugar can burn easily.
Once the sugar has reached the desired color, quickly whisk in the cubed butter until fully melted. Gradually pour in the heavy cream while stirring continuously. Be careful, as the mixture may bubble and splatter.
Once combined, stir in the sea salt, then take off the heat and let the caramel cool slightly for about 10 minutes.
Pour the salted caramel into the cooled tart crust, using a spatula to spread it evenly. Place the tart in the refrigerator for at least 1 hour to allow the filling to set.
Prepare the chocolate ganache: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Do not boil.
Remove the saucepan from the heat and add the semi-sweet chocolate chips. Stir gently until the mixture is smooth and shiny, and the chocolate is completely melted.
Carefully pour the ganache over the set salted caramel layer, spreading it evenly to cover the whole tart.
Chill the tart: Place the tart back in the refrigerator and let it chill for at least 2 hours, or until it is set thoroughly and firm to the touch.
Serve: Once set, slice the tart into wedges and serve chilled. For an extra touch, sprinkle additional sea salt on top just before serving.
Notes
Garnish with chocolate shavings or a drizzle of caramel sauce on the plate for an impressive look. Serve with a dollop of whipped cream for added richness!
