I would like to thank my friend in Berlin for sending me the recipe for this delicious tart. I am sorry that I didn’t do such a good job with the photos, but it tasted really good! I pinky swear it!
The fact that you can now buy cheap, ready made Dulce de Leche from Rewe was the reason I decided to make this tart for my birthday. And I wanted to test my brand new mixer 😀 Since I didn’t have a pie dish with a detachable bottom, I had to make peace with the fact that I wasn’t gonna lift perfect slices, despite oiling the pie dish very heavily.
If you don’t have pie weights, you could use dried beans, like chickpea. I used mung beans, which you could in turn make into guinataang munggo (remind me to share you the recipe one day).
The recipe was published in David’s book My Paris Kitchen. This is how I made this tart
For the Crust: 6 Tablespoons/ 85 g butter (preferably salted) at room temperature or softer, 3/4 cup powdered sugar, 1 large egg yolk, 1 cup flour, 1/3 cup cocoa powder, 1/4 tsp. flaky sea salt, and 1 Tablespoon water (optional)
Filling: 230 g chopped bittersweet or semisweet chocolate, 2 large eggs, 1/2 tsp vanilla, 1 cup (240 g) dulce de leche, and flaky sea salt for sprinkling.
Make the crust before the filling. Using a stand or hand-held mixer with a paddle attachment, beat the butter with the powdered sugar at low speed, until smooth. Mix in the yolk, occasionally stopping to scrape the sides of the bowl.
In another bowl, whisk the flour and the cocoa powder together, and add to the butter mixture until the dough comes together. If it looks dry, add a tablespoon of water (which I did). Roll into a ball. Pull a plate- sized (about 15 inches by 15 inches) portion of saran wrap (cling film) on a flat surface, place the dough ball on it, flatten a bit with the heel of your hand and wrap the dough in the film. Set aside for 30 minutes. You can also use a clean plastic bag, it is probably easier.
After 30 minutes, roll the dough relatively flat in the bag or unwrap the dough, place another sheet of cling film over it, and roll with a rolling pin. When the dough is wide enough to cover a 9 inch (23 cm) pie or tart ring with a removable bottom, remove the top sheet, place the dough in the tart ring by flipping it in using the plastic film for stability, and try to evenly cover the walls of the dish by pressing your fingers at the dough located at the bottom and sides of the dish and pushing the dough up the walls, until the rim. Sprinkle the sea salt over the dough and press it into the pastry. Cover the tart ring with the wrap you used to roll it in, and freeze for 30 minutes. Colder temperatures means that I could just open the balcony door and let it rest outside.
Pre-heat the oven to 200°C. Once the 30 minutes are up, line the dough with aluminum foil and cover the bottom with pie weights or dried beans. Bake for 30 minutes, remove the foil and the weights, and bake for 5 more minutes, until the shell feels set. Take the shell out of the oven and reduce the heat to 150°C.
During the waiting/baking period you can get cracking on the filling. Melt the chocolate in a bain-Marie, remove the bowl from heat once melted, and set a strainer on top.
Whisk the eggs into a bowl. Heat the milk in a saucepan until just warm, and whisk the milk into the eggs. Not too warm, we don’t want the eggs to scramble! Scrape the mixture back into the saucepan and cook over medium heat, stirring constantly with a spatula or a wire whisk, until it thickens slightly, about 3 minutes. Pour the custard through the strainer into the chocolate, and add the vanilla, stirring until smooth.
Carefully spread the Dulce de Leche over the hot tart shell in an even layer. It helps to let the Dulce sit for 30 seconds before spreading, the warmth of the tart bottom will soften the cream enough, making it easier to spread. Set the tart sheet on a baking sheet lined with aluminum foil, then carefully pur the chocolate custard over the dulce de leche. Smooth the top, and sprinkle with more salt.
Bake the tart for 20 minutes. Turn the heat off and leave the tart with the door closed for 25 minutes more.
You can remove it from the oven and let cool before serving. I just let the tart in the oven overnight and served it to my guests the day after.
David recommends serving it with whipped cream or vanilla ice cream, but the tart is so filling, I don’t think you will need more sweet! The crust tastes a lot like Oreo cookies, so it was really addictive.
