Combine eggs, sweetened condensed milk, evaporated milk, whiskey, vanilla extract, coconut extract, instant coffee granules, and chocolate syrup in a bowl; stir just enough to break the egg yolks into the mixture.
Pour the contents of the bowl into a blender; blend on High for 3 minutes.
Pour the blended mixture into a glass container with a tight-fitting lid. Refrigerate at least 2 weeks before serving.
