Chocolate Pate Sucree

Martha Stewart Living

Enough for one 9-inch tart

    1 1/4 cups flour                                               
    2 tablespoons cocoa powder                                     
    1/3 cup sugar                                                  
    1/2 teaspoon salt                                              
    6 tablespoons chilled unsalted butter pieced                   
    3 egg yolk                                                     
    1/2 teaspoon vanilla extract                                   

Place the flour, cocoa, sugar, and salt in the bowl of a food processor, and pulse several times to combine. Add the butter, and pulse until the mixture resembles coarse meal, about 10 seconds. Add the egg yolks and vanilla, and process just until mixture begins to hold together, no more than 30 seconds.

Turn dough out onto a lightly floured surface, and form into a disk. Cover in plastic wrap; refrigerate for 30 minutes, or until ready to use.
