Ingredients
  

For the Tart Crust
  • 1.5 cups all-purpose flour
  • 0.5 cup unsweetened cocoa powder
  • 0.5 cup powdered sugar
  • 0.5 cup unsalted butter, cold and cubed
  • 1 large egg yolk
  • 1 tablespoon cold water
For the Chocolate Filling
  • 8 oz dark chocolate (at least 60% cacao)
  • 0.5 cup heavy cream
  • 0.25 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
For the Spiderweb Decoration
  • 0.25 cup white chocolate chips
  • 1 tablespoon vegetable oil

Method
 

  1. Step 1: In a bowl, whisk together flour, cocoa powder, and powdered sugar. Cut in the cold butter until the mixture resembles coarse crumbs. Add egg yolk and cold water, mixing just until dough comes together.
  2. Step 2: Wrap the dough in plastic wrap and refrigerate for at least 30 minutes to firm up.
  3. Step 3: Preheat oven to 350°F (175°C). Roll out the chilled dough and fit it into a 9-inch tart pan. Prick the base with a fork.
  4. Step 4: Line the crust with parchment paper, fill with pie weights or beans, and bake for 15 minutes. Remove weights and parchment, then bake another 10 minutes. Cool completely.
  5. Step 5: Melt dark chocolate and heavy cream together in a heatproof bowl set over simmering water (or microwave in short bursts), stirring until smooth.
  6. Step 6: In a separate bowl, whisk together sugar, eggs, and vanilla. Slowly mix in the melted chocolate mixture until well combined.
  7. Step 7: Pour the filling into the cooled crust and bake for about 20 minutes, until set but still slightly soft in the center. Cool for 1 hour.
  8. Step 8: Melt white chocolate chips with vegetable oil. Transfer to a piping bag or small zip-top bag and snip the tip. Pipe circles onto the tart’s surface, then use a toothpick to drag lines from the center outward to create a spiderweb pattern.
  9. Step 9: Chill for at least 30 minutes before slicing and serving.

Notes

Pro Tips: Use high-quality dark chocolate for the richest flavor. If you prefer a softer texture, reduce baking time by a few minutes. Add an edible spider decoration for an extra Halloween touch!
