How to Make a Coffee Frappe. If you've got some coffee left over from breakfast, save it to make sweet, refreshing frappes later on. Yours just might be as good as that ubiquitous Seattle-based coffee chain's. Serves one.
Prepare 2/3 c. strong coffee.
While the coffee is still warm, add 1 tsp. sugar and stir until sugar is dissolved.
Add 1/3 c. milk and stir.
Place 1/2 c. ice in blender and add sweetened coffee.
Turn the blender on and off quickly a few times to break up the ice.
Add 2 tbsp. vanilla ice cream. Turn blender on to Medium and blend.
After the coffee and ice have blended, add another 1/2 c. ice.
Blend until smooth. If you want a thicker frappe, add a little more ice.
Pour into large glass and serve immediately.
