Dubai chocolate features a milk chocolate shell and a filling of pistachio, tahini, and knafeh. While the authentic bar is only available in Dubai, you can get copycats in the U.S.
On Amazon, you'll find a wide variety of Dubai chocolate from brands like Eastanbul, UniqBite, and Ceres Gourmet, which even makes a white chocolate version.
You can also get this viral chocolate online directly from other companies, including Ceres Gourmet and Dubai Chocolate Bar. These can be fairly pricey, however.
If you don't want to order the chocolate online, it is sold at several sweets shops in Michigan and is also gaining popularity in places like Long Island, New York.
You can make a copycat Dubai chocolate by melting milk chocolate into molds with deep reservoirs and filling them with a mixture of pistachio cream, kataifi, and tahini.
