Made this twice, but 2 different ways. With both slushies, I omitted the milk and added 1/2 cup of Coffee-Mate Tiramisu Coffee Creamer, and skipped adding the sugar all together. With the first slushie, I added a cup of ice cubes, and the tablespoon of instant coffee, but didn't care too much for the "strong" coffee flavor. With the second slushie, I added a cup of coffee flavored ice cubes, and just added 2 teaspoons of the instant coffee, and I liked this much better, so that's how I'm going to make my coffee slushies from now on. I'll enjoy making these using a varities of other liquid flavored coffee creamers.
