Directions

  1. 1Finely grind whole roasted pistachios in a food processor until a good portion is finely ground.
  2. 2Sift the ground pistachios into a large bowl.
  3. 3Continue grinding the larger pieces until you have 1 cup of pistachio flour.
  4. 4Set the pistachio flour aside.
  5. 5To make the crispy feuilletine, combine equal amounts of all-purpose flour and powdered sugar in a medium bowl.
  6. 6Pour in 2 tbsp of plain yogurt followed by 2 tbsp of melted butter.
  7. 7Mix until you have a smooth creamy batter.
  8. 8Spread the batter out as evenly and thinly as possible on a baking sheet lined with parchment paper, using a bench scraper.
  9. 9Bake in a preheated 340 degree oven for 10-15 minutes until brown and crispy.
  10. 10Allow to cool completely, then separate from the parchment paper and break the sheet into pieces that will fit inside a food processor.
  11. 11Pulverize the pieces until they are a fine crumb.
  12. 12Transfer to a bowl or container with a lid, cover, and set aside.
  13. 13Combine 1 cup of milk with 1 tbsp of vinegar to make a buttermilk substitute and let it sit for about 5 minutes.
  14. 14In a large bowl, add 1 cup of pistachio flour then sift in powdered sugar, baking powder, baking soda, and salt.
  15. 15Set the dry mix bowl aside.
  16. 16In a new bowl, mix together 1/4 cup of plain yogurt with 2 tbsp of melted butter.
  17. 17Gradually add the milk and dry mix into the butter and yogurt, mixing after each batch until everything is combined.
  18. 18Finally, sift in 1/2 cup of cake flour and mix until the batter is well combined.
  19. 19Transfer the batter to a greased and lined 9 1/2 by 13 inch sheet tray.
  20. 20Spread the batter out evenly by lifting and gently rotating the tray.
  21. 21Bake at 390 F for 10-15 minutes, then allow to cool completely.
  22. 22Flip the cake onto a cutting board and carefully remove the parchment paper.
  23. 23Cut the cake into 3 even slices and set aside.
  24. 24To make the chai syrup, add water, a cinnamon stick, 4 cardamom pods cut in half, 1-star anise, 4 whole cloves, 10-15 fennel seeds, 3 large slices of fresh ginger, and 2 tbsp of sugar to a saucepan.
  25. 25Turn the heat to medium-high and bring the mixture to a simmer.
  26. 26Cook for 10-15 minutes to infuse the flavors.
  27. 27Add 2 tbsp of black tea leaves and cook for another 5 minutes.
  28. 28Strain the syrup through a sieve, discard the spices, and save the syrup for later.
  29. 29Melt semi-sweet chocolate in a double boiler over recently simmering hot water.
  30. 30Once fully melted, remove from the heat and pour in the crispy feuilletine bits.
  31. 31Mix well, then spread evenly over one portion of the cake.
  32. 32Cover the chocolate coated cake piece and chill.
  33. 33Whip softened unsalted butter with an electric mixer or whisk until light and fluffy.
  34. 34Pour in 1/3 of a cup of sweetened condensed milk followed by 2 tbsp of the chai syrup.
  35. 35Mix again until fluffy to create the chai buttercream frosting.
  36. 36Make a simple chocolate ganache by pouring hot heavy cream over semi-sweet chocolate pieces.
  37. 37Cover and chill the ganache for 30 minutes to firm up.
  38. 38After chilling, fluff up the ganache again with an electric mixer so it’s easier to spread.
  39. 39Remove the chocolate-coated portion of cake, which should be firm enough to flip so the chocolate is on the bottom.
  40. 40Brush on a layer of chai syrup onto the cake.
  41. 41Add half the buttercream and spread it out evenly.
  42. 42Place the second piece of cake on top and brush on another layer of the chai syrup using a dab and brush motion.
  43. 43Top with the chocolate ganache and spread out evenly using a knife, spatula, or offset spatula.
  44. 44For the last layer, repeat with a layer of chai syrup followed by the other half of the buttercream spread out evenly.
  45. 45Chill the cake in the fridge for 30 minutes.
  46. 46When the cake is nearly done chilling, make a chocolate glaze by melting dark chocolate chips in a double boiler over recently simmering water with the stove turned off.
  47. 47Once the chocolate is mostly melted, pour in 1 tbsp of neutral oil and mix.
  48. 48Pour the chocolate glaze over your chilled cake placed on a cooling rack over a cookie sheet.
  49. 49Carefully spread the glaze out to get as even a layer as possible without dripping too much down the sides.
  50. 50Chill for 15 minutes to allow the chocolate glaze to firm up a bit.
  51. 51To make the cake look professional, slice off about 1/2 an inch from all sides.
  52. 52Decorate the cake as desired; for example, with a simple line of cold lustre dust along one edge.

Tips

  • Sift dry ingredients for cakes to avoid lumps.
  • Use a bench scraper to spread batter thinly and evenly.
  • When making chocolate glaze, turn off the stove after simmering water to avoid scalding the chocolate.
  • Slice off about 1/2 an inch from all sides of the cake for a professional look.
