1 1/4 cups all-purpose flour, spooned and leveled
1/4 cup unsweetened cocoa powder
1/2 tsp kosher salt, plus a pinch for the filling
1/2 cup (1 stick) unsalted butter, at room temperature
1/4 cup sugar
2 large egg yolks
1/2 lb semisweet chocolate, chopped
3/4 cup heavy cream
1) Heat oven to 350F. Spread the pecans on a rimmed baking sheet and toast, tossing once, until fragrant, 6 to 8 minutes. Let cool, then roughly chop. In a medium bowl, whisk together the flour, cocoa powder and salt.
2) Using an electric mixer, beat the butter and sugar on medium-high until creamy, 2 to 3 minutes. Beat in the egg yolks. Reduce mixer speed to low and gradually add the flour mixture; mix until combined but still crumbly.
3) Press the dough into the bottom and up the sides of a 4x14 inch rectangular (or 9 inch round) tart pan. Line with a large piece of parchment paper, leaving an overhang on all sides, and fill with dried beans or pie weights. Place the pan on a rimmed baking sheet and bake until the edges of the crust are dry, 20 to 22 minutes. Remove the parchment and weights, and bake until dry and set, 10 to 12 minutes. Let cool completely.
4) Meanwhile, in a large bowl, combine the chocolate and pinch of salt. In a small saucepan, bring the cream to a bare simmer; pour over the chocolate and let stand 1 minute. Stir gently until the mixture is smooth. Stir in 1 1/2 cups of the pecans. Pour the mixture into the cooled tart shell and sprinkle with the remaining pecans. Refrigerate until set, at least 1 hour.
Review: This is delicious!! I feared this would be just a crumbly candy bar. However, the filling was actually pretty creamy - almost like fudge. The crust was really crumbly and made a mess, but it was totally worth it.
