Chocolate Tartlets with Vanilla Custard

### **Instructions**

#### 1. **Prepare the Tart Crust**
1. In a large mixing bowl, combine the flour and powdered sugar. Add the cold butter and use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs.
2. Add the egg yolk and ice-cold water, mixing until the dough comes together. Avoid overworking the dough.
3. Wrap the dough in plastic wrap and refrigerate for 30 minutes.
4. Preheat the oven to 350°F (175°C). Roll out the chilled dough and press it into tartlet pans. Prick the bottoms with a fork to prevent puffing.
5. Bake the crusts for 12-15 minutes or until golden. Let cool completely.

#### 2. **Make the Chocolate Layer**
1. Heat the heavy cream in a small saucepan over low heat until warm (but not boiling).
2. Remove from heat and stir in the chopped chocolate until smooth.
3. Spread a thin layer of the chocolate mixture onto the cooled tart crusts and refrigerate for 10 minutes to set.

#### 3. **Prepare the Vanilla Custard**
1. In a medium saucepan, heat the milk over medium heat until it begins to steam (but not boil).
2. In a separate bowl, whisk together the egg yolks, sugar, and cornstarch until smooth. Gradually pour in the warm milk, whisking constantly.
3. Return the mixture to the saucepan and cook over medium-low heat, stirring constantly, until thickened. Remove from heat and stir in the vanilla extract.
4. Let the custard cool slightly before spooning it over the chocolate layer in the tartlets.

#### 4. **Assemble and Chill**
– Once filled, refrigerate the tartlets for at least 2 hours to fully set.
