Can you believe that I kept this in my fridge for a whole 24 hours just to bring into school to share? 24 hours. 24 long, long hours. I even gave the mini tarts to my roommates. I never had a taste for 24 hours! Ok, fine, that's a boldfaced lie. I had spoonfuls of curd and Nutella, and maybe a berry or thirteen while assembling this tart. I'm only human.
Chocolate Tart Dough
yields 4 2x4-inch rectangular tarts; or 1 9-inch round tart + some extra for mini tarts
1 1/2 cups all-purpose flour
1/4 cup unsweetened cocoa powder
1/2 cup sugar
1/2 teaspoon salt
1/2 cup (1 stick) chilled unsalted butter, cut into small pieces
2 large egg yolks
2 tablespoons heavy cream, chilled
1/2 teaspoon pure vanilla extract
Place flour, cocoa, sugar, and salt in the bowl of a food processor and pulse to combine. Add butter and pulse until mixture resembles coarse meal, about 10 seconds. Add yolks, cream, and vanilla and process until mixture comes together.
Turn out dough onto a piece of plastic wrap, flatten into a disk, and wrap. Refrigerate at least 30 minutes or until ready to use, up to 2 days.
Now it's time to make the tart! Preheat oven to 375 F. Remove dough from fridge and let sit on a floured work surface for 5 minutes. Roll dough about 1/4-inch thick. Press dough evenly into tart pan. Bake for about 20 minutes (You're whole house will smell like chocolate - this is the best part!). Remove from oven and let cool on a rack for an hour.
