Black-Bottom Hazelnut Pie

From the kitchen of Carly

Toasted hazelnuts meet dark chocolate in a buttery crust, building a pie that's nutty, rich, and dangerously easy to overeat. The chocolate layer grounds everything, while espresso and vanilla whisper in the background. Pure hazelnut heaven.

Black-Bottom Hazelnut Pie

Hazelnuts toasted until golden, then pulsed into a custard-like filling spiked with espresso and dark chocolate. The crust gets a chocolate layer first, a traditional move that keeps it crisp and adds richness without extra sweetness. What looks like a pecan pie is actually something better, nuttier, with an espresso note that makes your palate wake up.

Ingredients

4 servings

  • 2 tsp. granulated sugar
  • 1/2 tsp. kosher salt
  • 1 1/4 cupall-purpose flour, plus more for dusting
  • 1/2 cupunsalted butter, cut into pieces, frozen for 15 minutes
  • 3 cupblanched hazelnuts
  • 4 oz. bittersweet chocolate, chopped
  • 6 tbsp. unsalted butter
  • 1 cuplight brown sugar
  • 1 tbsp. instant espresso powder
  • 1 tbsp. vanilla extract
  • 1 cupplus 2 Tbsp. light corn syrup
  • 1 tsp. kosher salt, divided
  • 3 largeeggs
  • 1room temperature
  • 1beaten to blend

Instructions

  1. Pulse the granulated sugar, salt, and 1 1/4 cups of flour in a food processor briefly to combine. Add the butter and pulse until coarse, pea-sized crumbs form, around 10 seconds. With the motor running, stream in 2 tablespoons of ice water and process until the dough just begins to hold together, around 30 seconds. Pinch a small piece of dough between your fingers: if it crumbles, pulse in more ice water 1 tablespoon at a time (up to 2 tablespoons maximum). Stop the moment everything holds together. Don't overprocess.

  2. Turn the dough out onto a lightly floured surface and gather into a ball. Knead a few times to consolidate, then flatten into a disk with smooth edges (no cracks visible). Wrap tightly and refrigerate at least 1 hour.

  3. Roll the chilled dough out on a lightly floured surface into a 13 inch round. Loosely wrap the round around your rolling pin and transfer to a standard 9 inch diameter pie dish. Lightly press the dough into the pan, leaving a 1 inch overhang and trimming any excess. Fold the overhang under itself and crimp as you prefer. Chill until cold throughout, around 30 minutes.

  4. Make-ahead: the dough can be made and shaped into a disk 3 days ahead. Keep chilled, or freeze for up to 3 months. Thaw before rolling.

  5. Position racks in the bottom third and center of the oven and bring up to 375°F. Place a rimmed baking sheet on the bottom rack to preheat alongside the oven.

  6. Spread the hazelnuts across another rimmed baking sheet and bake on the center rack until light golden brown, around 10 minutes. Reserve 1 cup of whole hazelnuts to decorate the finished pie; finely chop the rest.

  7. Melt the chocolate in a small heatproof bowl set over a small saucepan of barely simmering water (don't let the water touch the bowl). Stir constantly until smooth and fully melted. (A microwave works equally well.) Pull from the heat and cool slightly. Spread the melted chocolate across the bottom of the cooled pie shell with the back of a spoon and chill until set, around 15 minutes.

  8. Melt the butter in a small skillet over medium heat or in a microwave-safe bowl in the microwave. Pour the melted butter into a large bowl. Whisk in the brown sugar, espresso powder, vanilla, 1 cup of corn syrup, and 3/4 teaspoon of salt until well combined. Whisk in the eggs, then fold in the chopped hazelnuts.

  9. Pour the filling into the prepared pie crust (don't overfill). In a small bowl, toss the whole reserved hazelnuts with the remaining 2 tablespoons of corn syrup and 1/4 teaspoon of salt. Arrange these glazed nuts decoratively on top of the pie. Place the pie dish on the preheated baking sheet on the bottom rack and bake for 20 minutes. Rotate the baking sheet and move it to the center rack. Continue baking, covering the crust edges with foil or a pie shield if they start to brown too much, until the crust turns golden brown and the filling is almost set with a slight jiggle at the center, 20 to 25 minutes more. Move the pie to a wire rack and cool completely before slicing, around 3 hours total.

  10. Make-ahead: the filling (before decorating the top) holds 1 day ahead. Bring to room temperature before baking. The fully baked pie holds 2 days ahead, loosely covered with foil at room temperature.

Tips from the kitchen

  • Freeze butter pieces for exactly 15 minutes before making crust. Cold fat means flaky layers, not dense pastry. Don't worry if ice water seems excessive; just enough to bind is the point.
  • Toast hazelnuts until they smell nutty and look light golden. Under-toasted nuts taste flat; over-toasted tastes bitter. Ten minutes is a guide, not a law.
  • Spread the chocolate layer thin on the pre-baked crust. It's a flavor anchor, not a fudge layer. Helps the filling set cleanly too.

Variations

  • Skip the espresso powder if you want pure hazelnut. The filling will taste brighter, less grounded.
  • Brown the butter for the filling instead of using it straight. Nutty brown butter doubles down on hazelnut flavor and adds toasted depth.
  • Use half blanched hazelnuts and half roasted for more assertive flavor. Roasted nuts bring crunch and deeper taste.

Make ahead and storage

Wrap leftover pie loosely in plastic or foil and refrigerate for up to 4 days. Freezes beautifully for up to 3 months. Thaw at room temperature before serving, or warm gently in a 300°F oven for 10 minutes.
