How to Make Chocolate Biscuit Turrón

• Prep: Roughly break the María cookies into bite-sized pieces. Do not crush them too finely because you want visible pieces of cookie throughout the finished turrón.
• Melt the Chocolates: Add the chocolate, white chocolate, and sweetened condensed milk to a heat-safe bowl. Place the bowl over a pot of gently simmering water and stir until everything is completely melted and smooth.
• Add the Cookies: Remove the chocolate mixture from the heat. Add the María cookies and salt, then gently mix until all the cookie pieces are evenly coated in chocolate.
• Shape the Turrón: Transfer the mixture onto a large piece of plastic wrap. Use the plastic wrap to shape and roll the mixture into a firm cylinder.
• Chill: Wrap the chocolate log tightly and refrigerate for 2 hours, or until completely firm.
• Decorate: Remove the plastic wrap and lightly dust the outside with powdered sugar.
• Slice and Serve: Cut the chilled turrón into thick slices and serve cold or let it sit at room temperature for a few minutes for a slightly softer texture.
