Step 1 Brew three shots of espresso using an espresso machine, Moka pot, or AeroPress. If you do not have espresso equipment, brew a small concentrated cup of strong coffee using a 1 to 6 coffee-to-water ratio. Let it cool for one to two minutes.
Step 2 Add four pumps of white chocolate mocha sauce into the bottom of a 24-ounce glass or cup. Pour the hot espresso directly over the sauce and stir vigorously until the sauce is fully dissolved.
Step 3 Fill the cup with approximately two cups of ice.
Step 4 Pour cold whole milk or your preferred milk alternative over the ice until the cup is nearly full. Stir once more to combine all layers evenly.
Step 5 Top with whipped cream and an optional caramel drizzle. Serve immediately with a straw and enjoy your homemade venti iced white mocha.
