Equipment

  • 9”-diameter tart pan with removable bottom

Ingredients
  

Crust

  • 2 Tbsp unsweetened cocoa powder
  • 2 Tbsp sugar
  • 3/4 tsp fleur de sel
  • 1 1/4 cup all-purpose flour + more for rolling
  • 1/2 cup unsalted butter, chilled cubed
  • 1 large egg yolk

Maple Hazelnuts/Almonds

  • 1/2 cup raw hazelnuts (or almonds, or nut of your choice)
  • 1/2 cup maple sugar or (packed) brown sugar
  • 1 Tbsp pure maple syrup
  • 1/4 tsp fleur de sel

Filling

  • 10 ounces bittersweet chocolate (at least 70% cacao), chopped
  • 1/4 cup unsalted butter cubed, roughly
  • 1 1/2 cup heavy whipping cream
  • 3 Tbsp honey
  • 1/2 tsp fleur de sel

Instructions
 

Crust

  • Pulse cocoa powder, sugar, salt, and 1¼ cups flour in a food processor to combine. Add butter; pulse until mixture resembles coarse meal. Beat egg yolk and 3 Tbsp. ice water in a small bowl; add to flour mixture and pulse until dough just comes together. Form into a ¾”-thick disk, wrap tightly in plastic, and chill until firm, at least 2 hours.
  • Preheat oven to 350°. Roll out dough on a lightly floured surface to a 12” round. Transfer to tart pan; lift up edges and let dough slump down into pan, then gently press into edge of pan. Trim dough, leaving about a 1” overhang. Fold in overhang; press to adhere. Prick bottom with a fork. Chill in freezer 15 minutes
  • Line pie with parchment paper or heavy-duty foil, leaving a 1½” overhang. Fill with pie weights or dried beans. Place on a rimmed baking sheet and bake until crust is dry around the edges, about 30 minutes. Remove parchment and weights and bake until crust is firm and looks dry all over, 5–10 minutes longer. Transfer pan to a wire rack and let crust cool.

Maple Hazelnuts/Almonds

  • Preheat oven to 350°. Toast almonds on a rimmed baking sheet, stirring occasionally, until slightly darkened, 6–8 minutes. Let cool.
  • Bring almonds, maple sugar, maple syrup, salt, and ¼ cup water to a boil in a medium saucepan. Reduce heat and cook, stirring often, until mixture turns mahogany, about 5 minutes.
  • Remove pot from heat and stir vigorously until almonds are coated with crystallized sugar (they will look sandy). Spread out on a parchment-lined baking sheet; let cool, then coarsely chop.

FILLING AND ASSEMBLY

  • Combine chocolate and butter in a large heatproof bowl. Bring cream, honey, and salt to a boil in a small saucepan, whisking to dissolve honey. Pour cream mixture over chocolate mixture; let stand 2 minutes. Whisk until chocolate is melted and mixture is smooth. Pour filling into crust and chill until set, at least 4 hours.
  • Top tart with maple almonds just before serving.
