This Starbucks white chocolate mocha sauce is one of my favorite homemade coffee recipes to keep in the fridge. It’s rich, creamy, and designed to recreate the flavor and texture of the white chocolate syrup Starbucks uses in drinks like white chocolate mochas, frappuccinos, and seasonal favorites.
Unlike store-bought sauces, this recipe uses simple dairy ingredients you can easily find at the grocery store, no specialty cocoa butter or hard-to-find products required. It melts smoothly into hot drinks, blends beautifully into iced coffee, and thickens just enough in the fridge to feel like the real thing.

Let’s Chit Chat!
White chocolate has always felt like one of those quietly luxurious flavors to me. I’ve been making this white mocha sauce ever since my husband and I got together, and it’s become one of our favorite little indulgent treats.
Because this recipe makes a smaller batch, it’s perfect for just the two of us. It feels special without being over-the-top, whether we’re making iced lattes, warm milk with a spoonful of sauce, or recreating our favorite Starbucks drinks at home, it’s truly the best!
Honestly, once you realize how easy it is to make, it’s hard to go back to paying $5–$8 per drink.

Why This White Chocolate Mocha Sauce Works
- Made with real white chocolate for authentic flavor
- Sweetened condensed milk adds richness and sweetness similar to Starbucks
- A blend of heavy cream and evaporated milk creates a smooth, pourable sauce
- Thickens naturally in the fridge, just like Starbucks sauces
- Melts easily into hot drinks and blends smoothly into iced coffee
This recipe was tested specifically so it behaves like a true white chocolate mocha sauce, not a grainy or overly thin syrup.

It’s great that you gave us the nutrition value. But you say NOTHING about if it is for 0.1 micro tsp, full teaspoon, tablespoon, cup, half cup?????? Why is this not published and do you know the volume for which it was computed? If so, can you provide this information?????

Hi, what is the serving size in the recipe?
You can make around 12 cups of white chocolate mocha lattes, give or take how much you use.
