Place the coffee in the refrigerator to let it chill.
Add coconut milk in a saucepan.
Heat over medium high heat while whisking continuously, until it starts to boil.
Immediately reduce the heat to low to simmer once it starts boiling, then add maple syrup.
Simmer while whisking occasionally for 30 minutes, or until the mixture is reduced to half.
Stir in cardamom powder and almond extract.
Remove from heat and let it cool.
To make the Thai iced coffee, place ice cubes in 4 glasses.
Divide the coffee into the glasses.
Whisk the sweetened condensed coconut milk if it's separated, and pour over the coffee.
Stir together and enjoy! You can add more dairy free milk if you want it creamier.
Leftover condensed coconut milk will last up to a week in the refrigerator in an airtight container.
