This Starbucks Black Cat Frappuccino copycat is a homemade version of the chocolatey Halloween drink. It blends milk, cocoa, chocolate syrup, and ice for a creamy frozen treat, topped with whipped cream and edible chocolate cat ears.
Inspired by the U.S. Starbucks version, this recipe aims for a rich, brownie-like chocolate flavor without coffee or raw cake mix. All you need is a blender and a few simple ingredients.
Ingredients You’ll Need
You only need a few ingredients to make this chocolatey frozen drink at home.
- Whole milk: Creates the creamy base of the Frappuccino.
- Chocolate syrup: Adds chocolate flavor and sweetness.
- Dutch-process cocoa powder: Gives the drink a rich chocolate flavor.
- Black cocoa powder: Helps create a deeper, darker chocolate color.
- Light brown sugar: Adds a little extra sweetness.
- Xanthan gum: A small amount helps keep the blended drink smooth and limits separation.
- Salt: Balances the sweetness and chocolate flavor.
- Ice cubes: Give the Frappuccino its thick, frozen texture.

For the Whipped Cream and Chocolate Cat Ears
- Heavy whipping cream: For the creamy topping.
- Powdered sugar: Lightly sweetens the whipped cream.
- Semisweet chocolate chips: Melted and shaped into edible cat ears.

How to Make a Black Cat Frappuccino
1. Make the Chocolate Cat Ears
Melt the chocolate chips in the microwave in 10–15 second intervals, stirring between each. Transfer the melted chocolate to a small piping bag. Pipe four filled triangles onto parchment paper, leaving a short chocolate tab at the bottom of each one. Refrigerate for 10–15 minutes, or until firm.

2. Whip the Cream
Beat the cold heavy whipping cream and powdered sugar until medium peaks form. Refrigerate while you prepare the drink.

3. Mix the Chocolate Base
In a small bowl, combine the Dutch-process cocoa, black cocoa, brown sugar, xanthan gum, and salt. Add the cold milk and chocolate syrup to a blender, followed by the dry ingredients. Blend briefly until combined.

4. Blend with Ice
Add the ice cubes and blend until the mixture is smooth and thick, with no large ice pieces remaining. Avoid blending longer than necessary.
5. Assemble and Serve
Pour the Frappuccino into a tall glass and top with whipped cream. Carefully insert two chocolate cat ears into the cream, using their chocolate tabs to hold them in place. Serve immediately.
Tips for the Best Black Cat Frappuccino
- Start with cold milk. Cold ingredients help keep the drink thick and frozen while blending.
- Measure the ice. Ice cubes vary in size, so weighing them gives you a more consistent starting point.
- Mix the dry ingredients first. Combining the cocoa powders, brown sugar, xanthan gum, and salt helps distribute the small amount of xanthan gum more evenly.
- Avoid overblending. Stop once the drink is smooth and the ice is crushed. Blending too long can melt the ice and thin the mixture.
- Keep the toppings chilled. Make sure the chocolate ears are firm and the whipped cream is cold before assembling. Add both just before serving.
Substitutions and Variations
A few simple swaps are possible if you don’t have every ingredient:
- No black cocoa powder? Replace it with an equal amount of Dutch-process cocoa powder. The drink will have a lighter chocolate color.
- No xanthan gum? You can leave it out. The Frappuccino may separate more quickly, so serve it immediately.
- No chocolate chips? Use chopped semisweet chocolate to make the cat ears. Melt it gently and let the shapes firm up before decorating.

Make-Ahead and Storage
This Black Cat Frappuccino is best served immediately after blending. The ice will melt as the drink sits, making it thinner, so storing the finished drink isn’t recommended.
Make ahead: You can prepare the chocolate cat ears a day in advance and keep them in an airtight container in the refrigerator. The whipped cream can also be made a few hours ahead and refrigerated in a covered container.
For the best texture, blend the Frappuccino just before serving and add the toppings at the end.
