Place all ingredients except whipped cream in blender.
Blend until ice cubes are crushed. If you have trouble getting it thoroughly blended, let it sit for a couple of minutes and try again.
Top with whipped cream and drizzle with caramel syrup.
Notes
For me, 1 cup is 7 ice cubes.
To cut calories a bit, I now sub some of my favorite stevia for part of the sugar. By using some sugar, I don’t notice that unique stevia taste, but still get the benefit of fewer calories.
If you want a stronger coffee flavor, add just a bit of instant coffee.
If you aren't using a high-powered blender and are having trouble getting the coffee ice cubes to blend you can try:
letting the ingredients sit in the blender for 15 to 20 minutes before blending
defrosting the ice cubes in the microwave for 30-45 seconds. Do it just long enough to soften them slightly, but not long enough to melt them and lose the slushiness that they give the frappe.
