Preheat your waffle iron according to manufacturer's instructions.
In a large mixing bowl mix melted butter, coconut milk, water, ube extract if using, and eggs one at a time.
Pour in 1/2 of the ube mochi waffle mix and whisk until well combined. Repeat. Be careful not to overmix; a few lumps are okay.
Lightly grease the waffle iron with cooking spray or melted butter.
Pour enough batter onto the waffle iron to cover the waffle grid, add a tablespoon of ube jam to the center and pour batter enough to cover jam, close the lid and cook according to the waffle iron's instructions, usually for about 3-4 minutes or until golden brown.
Carefully remove the waffles from the iron and serve warm with your favorite toppings such as whipped cream.
