Start by crushing the chocolate cookies in a food processor until they resemble fine crumbs. Melt the unsalted butter and mix it with the cookie crumbs until well combined. Press this mixture firmly into the bottom of a 9-inch springform pan, ensuring an even layer. Refrigerate for about 20 minutes while you prepare the next layer, allowing the crust to set.

In a skillet over medium heat, melt some butter and add the kataifi pastry, stirring frequently until it turns golden brown and crispy, about 5-7 minutes. Remove from heat and let it cool slightly. Combine the toasted kataifi with pistachio cream and a pinch of salt, then evenly layer this mixture over the chilled crust, pressing it down gently to create a compact layer.

In a small saucepan, heat the heavy cream over low heat until it begins to simmer, about 3-4 minutes. Remove it from heat and pour it over the chopped dark chocolate in a bowl. Let it sit for a minute, then stir until the mixture is smooth and glossy. Carefully spread the chocolate ganache over the knafeh layer, ensuring an even covering, and refrigerate for 15 minutes for it to set.

In a large mixing bowl, whisk the cream cheese, powdered sugar, fine salt, and vanilla extract until creamy and smooth, which should take about 3-4 minutes. Gently fold in the pistachio cream until well blended. In a separate bowl, whip the heavy cream until soft peaks form, then gently fold this into the cheesecake mixture for a light texture, being careful not to deflate it.

Once your filling is prepared, take the springform pan from the fridge and carefully spread the cheesecake mixture over the ganache layer. Use a spatula to smooth the top evenly, creating a beautiful surface for your No Bake Dubai Chocolate Cheesecake. Cover the cheesecake with plastic wrap and refrigerate for at least 6 hours, or overnight, for the best results.

After the cheesecake has set, remove it from the refrigerator. Carefully release the springform pan and remove the sides. For an elegant presentation, drizzle with additional ganache and garnish with crushed pistachios or chocolate shavings. Your No Bake Dubai Chocolate Cheesecake is now ready to impress at any gathering!
