Ingredients

Frappuccino Base Syrup

1 Cup Filtered Water
3/4 Cup Sugar
1 tsp Xanthan Gum
1 tsp Vanilla Extract

Classic Coffee Frappuccino

½ cup strong coffee, fully chilled (or cold espresso)
½ cup milk (any kind)
2–3 Tbsp Frappuccino base syrup (start at 2 Tbsp)
1 to 1½ cups ice (start at 1 cup; add more for thicker)
Pinch of salt (optional, but helps)

Instructions

Step 1: Make a Frappuccino Base Syrup (5 servings)

Warm water + sugar in a small pan, stirring until fully dissolved. Let it cool to room temp.
Pour cooled syrup into a blender, add xanthan + vanilla, and blend until smooth and slightly thick.
Store in a jar in the fridge. Stir before each use.

Step 2: Make a Classic Coffee Frappuccino (1 large / ~16 oz)

Add coffee + milk + base syrup to the blender first.
Add ice on top.
Blend on high until smooth (usually 20–30 seconds, depending on blender).
Taste: add another spoon of base syrup for sweeter/thicker, or more ice for thicker.

Notes

Quick fixes (so it doesn’t separate)

Coffee must be cold before blending (hot coffee melts ice fast and thins the drink).
If you want it extra stable: use coffee ice cubes for part of the ice (keeps flavor strong as it melts).
If it’s gummy/stringy: you’re using too much xanthan in the drink—stick to the measured base syrup.

Two “Reliable” Flavor Versions

Caramel Frappuccino-style

Add 1–2 Tbsp caramel sauce to the blender (plus drizzle on top if you want).
This general build is widely used in tested copycat recipes.

Mocha Frappuccino-style

Add 1–2 Tbsp cocoa powder (or chocolate syrup), blend with the coffee before ice if possible.
The “dissolve first, then ice” approach is a common trick for smoother results.
