Brew coffee in an espresso machine or drip coffee maker. Cool it to avoid melting down the drink.
Drizzle some chocolate syrup on the sides of a tall glass and set it aside.
Put the cold coffee, milk, chocolate chips, chocolate syrup, and ice into a high-speed blender. If you love the texture of the Starbucks Java Chip, you can add chocolate cookies.
Use the blender’s low setting for 30 seconds, then blend the mixture at a maximum speed for 10 seconds until it’s evenly smooth. Stop once or twice to stir and ensure it mixes uniformly.
Pour the smooth blend into your garnished glass.
Top off the drink with whipped cream and a drizzle of chocolate syrup.
Serve your frappuccino immediately to avoid watering it down.
