Over the past month I have been tweaking the recipe quite a bit, so I think it's best to write it down now. When summer rolls around again, I don't want to be left standing at the blender starting from scratch.
2 scoops ice cream (caramel swirl works great)
1 cup ice
1 1/2 cup chilled coffee
1/2 cup milk
1 1/2 Tablespoons simple syrup
Put everything in your blender and mix well.
Can be topped with whipped cream.
