Brew a cup of strong coffee using your preferred method. Allow it to cool completely or chill it in the refrigerator.

In a blender, combine the cooled coffee, milk, chocolate syrup, granulated sugar, and ice cubes.

Blend on high speed until the mixture is smooth and creamy, with no visible chunks of ice remaining.

Taste the Mocha Frappuccino and adjust the sweetness level by adding more sugar or chocolate syrup if desired.

Once you're satisfied with the taste, pour the Frappuccino into serving glasses.

Top each glass with a generous dollop of whipped cream.

For an extra touch of indulgence, sprinkle chocolate shavings or cocoa powder over the whipped cream.

Insert a straw into each glass, give it a quick stir if desired, and enjoy your homemade Mocha Frappuccino!
