Kahlua - What is it made from?

My housemate and I both decided it’s a slight coffe flavour that tastes more like chocolate because of the sweetness. 5% coffee, 95% chocolate taste.

What is Kahlua made from?

4 oz instant coffee
2 oz vanilla
5 lbs sugar
1/2 gallon water
1.75 liter vodka

Heat ingredients except vodka to a slow boil. DO NOT BURN!
Let cool. Add vodka
Bottle it
Store in cool dark place for as long as you can wait.
Enjoy
