Equipment

  • Oven
  • Baking Sheet
  • Food Processor
  • Chocolate bar mold

Ingredients
  

For the Crunch Layer

  • 1 cup kataifi pastry roughly chopped (approx. 3.5 ounces), OR 1.5 cups crushed cornflakes
  • 1 tbsp unsalted butter or neutral coconut oil optional, for kataifi

For the Chocolate Layers

  • 1 cup milk or dark chocolate chopped, good quality (approx. 5.6 ounces)
  • 1.5 tbsp white chocolate finely chopped (approx. 0.7 ounces), optional, for decorative drizzle
  • A few drops green food coloring optional

For the Creamy Pistachio Filling

  • 1.5 cups raw shelled pistachios (approx. 7 ounces)
  • 2 tbsp melted neutral coconut oil divided (or tahini for the filling)
  • 1/4 cup non-fat milk powder
  • 2.5 tbsp powdered sugar or other sweetener, to taste
  • Pinch sea salt
  • 1.5 tbsp shelled salted pistachios peeled, roughly chopped (approx. 0.7 ounces), optional, for extra crunch

Instructions
 

  • 1. Prepare Your Crunch Layer: Preheat your oven to 350°F (180°C). If using kataifi pastry, gently melt 1 tablespoon of butter or coconut oil on a shallow baking sheet. Toss the chopped kataifi in the melted fat until coated. Bake for about 30 minutes, stirring every 10 minutes, until it turns golden and crispy. Remove from oven and let it cool completely. (If using cornflakes, simply crush them into small pieces and set aside.)
  • 2. Toast the Pistachios: Spread the raw shelled pistachios in a single layer on a separate baking sheet. Bake alongside the kataifi for about 15 minutes, until they smell wonderfully toasty. Let them cool down. For a brighter green color (optional), rub the cooled pistachios in a clean tea towel or shake them vigorously in a large jar to help remove the papery skins, then pick them out by hand. Roughly chop the pistachios.
  • 3. Melt and Set the Decorative Layer (Optional): If you're adding a decorative touch, melt the 1.5 tablespoons of white chocolate in a heatproof bowl placed over a pot of gently simmering water (don't let the bowl touch the water). Stir in a few drops of green food coloring if desired. Drizzle or spoon this green white chocolate mixture onto the bottom of your chocolate bar mold (a 10x5 inch bar mold works well), then place it in the fridge to set firmly.
  • 4. Melt the Main Chocolate: Chop your milk or dark chocolate into small pieces. Gently melt about two-thirds of the chopped chocolate using the same simmering water method (or in a microwave in short 15-second bursts, stirring between each). Once melted and smooth, stir in the remaining one-third of the chopped chocolate until it's all melted and smooth. This helps create a firmer, glossier bar.
  • 5. Create the Chocolate Shell: Pour just enough melted chocolate into your mold (over the set green white chocolate, if using) to thoroughly coat the bottom and sides, creating a shell. Tilt the mold to ensure even coverage. Place the mold in the fridge for about 30 minutes until the chocolate shell is firm.
  • 6. Make the Creamy Pistachio Filling: While the shell chills, add the chopped pistachios to a food processor or blender. Process until they are finely ground and start to look slightly oily and clump together. Add 1 tablespoon of the melted neutral coconut oil (or tahini), milk powder, desired amount of powdered sugar, and a pinch of salt. Blend again until the mixture is well combined and creamy. Taste and adjust sweetness if needed. Stir in the optional shelled salted pistachios for extra texture.
  • 7. Assemble Your Bar: Once the chocolate shell is firm, gently fold the cooled kataifi crunch (or crushed cornflakes) into the pistachio filling mixture until everything is well combined. Spoon this delicious filling into the chocolate shell in your mold, spreading it evenly and leaving a small gap around the edges. You can run a butter knife around the edge to create a neat border.
  • 8. Seal and Chill: Re-warm any remaining melted chocolate if it has hardened. Pour it over the pistachio filling, tilting the mold to spread it to the edges and completely encase the filling.
  • 9. Set and Enjoy: Chill the chocolate bar in the fridge for at least 2 hours, or until it's completely firm. Carefully unmold the bar and slice it into your desired portions. Enjoy this refreshing, crunchy treat!
  • 10. Optional Individual Bites: For bite-sized delights, form the pistachio filling into small, roughly 20g balls. Chill them until firm (about 30 minutes). Dip each ball into melted chocolate to coat, then return to the fridge to set. Decorate with a dab of green white chocolate or a whole pistachio on top while the chocolate is still slightly tacky.

Notes

Feel free to swap kataifi pastry with crushed cornflakes for the crunch layer. You can also make individual bite-sized treats by forming the pistachio filling into balls and dipping them in chocolate.
