This is the best "Kahlua" recipe I've found. I added about 1/4 cup brandy to the recipe.
coffee beans, whole
two to three inches
Combine water, sugar, and coffee in a saucepan and bring to a full boil.
Skim off the froth and allow to cool thoroughly.
Pour into the container. Add vodka, coffee beans (optional but will add a fuller flavor), and vanilla bean.
Store in a dark place for 3 weeks. Strain and filter. Ready to serve.
