Instructions
To Make the Dark Chocolate Genoise:
  1. Preheat the oven to 450 degrees F and mist a 12x17" rimmed baking sheet with non-stick spray. Line with parchment, mist again, and dust with cocoa powder. Tap out excess, and set aside.

  2. Place the cocoa, flour, and salt in a bowl and whisk to combine.
  3. Place the eggs, yolks, and sugar in a large mixing bowl set over a pot of simmering water, and whisk together until the sugar is dissolved and the mixture feels warm.

  4. Whip the egg mixture on high speed until very pale in color and thick (about 5 minutes).
  5. Fold in the dry ingredients.

  6. When they are almost completely incorporated, add the melted butter and continue to fold until combined.

  7. Spread the batter into the prepared baking sheet, and bake for 7 minutes or until springy to the touch.
  8. Meanwhile, overlap 2 long sheets of paper towels and dust with cocoa. When the cake has cooled slightly, run a thin knife around the edge and then invert onto the towels. Roll (while still warm) starting from one short side and incorporating the towels.

  9. Allow the cake to cool completely, rolled.

  10. Fill with Matcha Green Tea Buttercream, dust with powdered sugar, matcha, and cocoa, and decorate with Hairy Spider Cookies.

To Make the Matcha Green Tea Buttercream:
  1. Place the egg whites and sugar in a large mixing bowl, and place over a pot of simmering water.

  2. Cook, whisking occasionally, until the mixture no longer feels gritty when rubbed between the thumb and forefinger.

  3. Remove the egg white mixture from the heat, and whip on medium-high speed until there is no hint of warmth remaining, and the meringue holds stiff peaks.
  4. Add the butter, a tablespoon at a time, while continuing to whip on medium-high speed.
  5. Stir in the matcha powder.

  6. (If the buttercream seems runny, place the bowl in the refrigerator for 10-20 minutes, then whip again until fluffy and stiff.)
