1 2/3 cups Irish whiskey (Jameson)
one 14-ounce can sweetened condensed milk
1 cup half-and-half or heavy cream (I used half-and-half)
2 tablespoons chocolate syrup
2 teaspoons vanilla extract
1 teaspoon instant coffee granules or instant espresso (make sure it's instant so it dissolves)
Mix all ingredients well in a blender.
Store in the refrigerator in an air tight container.
