1 (14 ounce) can sweetened condensed milk
1 (12 ounce) can evaporated milk
1 1/2 cups high-quality Canadian blended whiskey, or more to taste
1 teaspoon vanilla extract
1 teaspoon coconut extract
1 teaspoon instant coffee granules
1 tablespoon chocolate syrup
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.
