Tiramisu. Truffles. Cheesecake. None of these delectable desserts would be the same without coffee liqueur. However, if coffee liqueur is not readily available in your kitchen cabinets, you can easily make a substitute out of readily-available ingredients. Although these substitutions will not be perfect replicas of coffee liqueur, they will add the necessary strong chocolate and coffee flavors to your desserts.
Use espresso as a non-alcoholic substitution for coffee liqueur. You can make this substitute with either regular or instant espresso. Brew the espresso strong. Add unsweetened cocoa powder to the espresso, and sweeten it with sugar to taste.
Make a substitute for 2 tbsp. of coffee liqueur by mixing 1 tsp. of instant coffee with 2 tbsp. of water and 1/2 to 1 tsp. of chocolate extract. If you do not have chocolate extract, use unsweetened cocoa powder and sweeten the mixture to taste with sugar.
Coffee-flavored syrup can substitute for coffee liqueur. Supermarkets usually carry this syrup. Add unsweetened cocoa powder to the syrup for a true coffee liqueur flavor.
Mix non-alcoholic coffee extract and cocoa powder together for a coffee liqueur substitute. Add the cocoa powder slowly until you arrive at the desired taste. Add sugar to sweeten. You can purchase non-alcoholic coffee extract at most supermarkets.
