Dark Chocolate Truffle Tart

• 1/3 cup confectioners' sugar
• 1/3 cup walnut halves, toasted
• 1/2 cup all-purpose flour
• 3 tablespoons baking cocoa
• 1/8 teaspoon salt
• 1/3 cup cold unsalted butter, cubed
• 8 ounces semisweet chocolate, chopped
• 1/4 cup unsalted butter
• 2/3 cup heavy whipping cream
• 1-1/4 teaspoons instant espresso powder
• 2 large eggs, lightly beaten
• 1 large egg yolk
• 1/3 cup sugar
• 1-1/2 teaspoons vanilla extract
• Additional baking cocoa

1. Preheat oven to 350u0b0. Place confectioners' sugar and walnuts in a food processor; pulse until walnuts are finely chopped. Add flour, cocoa and salt; pulse until blended. Add butter; pulse until mixture resembles coarse crumbs.
2. Press dough onto bottom and up sides of a greased 9-in. fluted tart pan with removable bottom. Refrigerate 30 minutes. Bake 10 minutes.
3. Meanwhile, for filling, in a double boiler or metal bowl over hot water, melt chocolate and butter; stir until smooth. Stir in cream and espresso powder. Remove from heat; cool slightly. Whisk in eggs, egg yolk, sugar and vanilla.
4. Pour filling into warm crust. Bake 20-25 minutes or until center is just set (mixture will jiggle). Cool completely on a wire rack. Dust with cocoa before serving.
