Heat vegetable oil in a frying pan to 350°F.
Fry the shredded phyllo until golden and crispy. Use a slotted spoon to transfer the fried phyllo to a plate lined with a paper towel to drain excess oil.
Allow the fried phyllo to cool down for 15 minutes.
Mix the pistachio paste with the fried phyllo in a mixing bowl.
Optional: Drizzle a little white chocolate into the chocolate mold.
Pour about 1/4 cup of melted milk chocolate into the mold and shake to cover the bottom and sides. Place in the fridge or freezer for 10 to 15 minutes to harden.
Fill the mold with the pistachio and phyllo mixture almost to the top.
Cover the filling with more melted chocolate and place back in the fridge or freezer for another 10 to 15 minutes until set.
Once hardened, pop the chocolate out of the mold and enjoy!
