This iced blended coffee is built from three things only: real brewed coffee, dairy and a sweetener. There is no commercial base mix, ice cream, pudding or drink powder, and no instant coffee or espresso powder. Coarsely ground beans steep in cold water for 12 hours, part of the brew is mixed with half and half, and the rest is frozen into coffee ice cubes.
The quantities are given by weight, with approximate cup measures in parentheses. Weighing matters most for the ice, because cube sizes differ from tray to tray, and it makes the drink repeatable. It also makes adjusting easy: cutting back the coffee base thickens the drink, and adding more thins it.
Any coffee works, from light or medium roasts to French roast or espresso beans; an espresso roast gives the ice cubes a deep brown color. Going all decaf, or half decaf and half regular, lowers the caffeine. A high-powered blender gives the best texture.

Iced Blended Coffee Beverage
Ingredients
Method
- Grind the coffee beans coarsely, as for a French press.
- Put the grounds in a 51-ounce (12-cup) French press or a large clean glass jar. Pour in about 1 cup of the cold filtered water and stir gently with a wooden spoon until all of the grounds are wet, then add the rest of the water. Leave some space at the top for the plunger.
- Cover the press or jar with a lid or a small plate and refrigerate for 12 hours.
- Take the press out of the refrigerator and uncover it. Fit the plunger lid with the plunger pulled all the way up, then push it down slowly and evenly as far as it will go. For coffee steeped in a jar, pour it through a cloth or paper coffee filter set in a mesh strainer over a second clean container.
- In a clean container, stir together 177 grams (3/4 cup) of the coffee and the half and half or a substitute. Cover and refrigerate.
- Freeze the rest of the coffee in ice cube trays until solid, at least 4 hours or overnight.
- Put the ingredients into the blender pitcher in the order listed: coffee base, sugar, xanthan gum if using, then the coffee ice cubes.
- Blend on high, or on the setting the blender’s manufacturer recommends, for 45 to 60 seconds, until smooth and as thick as desired. Pour into a 16-ounce glass and serve right away.
