Using your favorite blender, blend all ingredients until smooth and creamy.
Pour into your favorite glass or mug.
Garnish with chocolate-covered coffee beans and whipped cream. (Optional)
For a stronger coffee flavor, use more instant coffee or espresso.
You can also add other flavorings to your milkshake, such as chocolate syrup, caramel sauce, or hazelnut syrup.
If you don't have instant coffee, you can use brewed coffee instead. Just make sure to cool it down before adding it to the blender.
This milkshake is also a great way to use up leftover ice cream.
