What Goes Into This Delicious Sauce
- White Chocolate: I used Ghirardelli baking squares, but any good-quality white chocolate works. White chocolate chips are fine if that’s what you have!
- Sweetened Condensed Milk: Brings the sweetness and that thick texture we love.
- Evaporated Milk: Prevents the sauce from hardening as it cools.
- Vanilla Extract: Just a splash for a little depth of flavor.

Can I Make it Dairy-Free?
You sure can! Here are the substitutes I would recommend:
- White Chocolate: Use dairy-free white chocolate, such as Pascha, King David or Enjoy Life.
- Sweetened Condensed Milk: Swap with sweetened condensed coconut milk. Brands like Nature’s Charm work well.
- Evaporated Milk: Use evaporated coconut milk.
How to Make White Chocolate Sauce
- Step 1: Add sweetened condensed milk, evaporated milk, and white chocolate squares to small saucepan.
- Step 2: Stir the mixture over low to medium heat, slowly heating the mixture until the chocolate melts.
- Step 3: Once the chocolate has melted and the mixture is smooth, remove from heat and stir in the vanilla extract.
- Step 4: Pour the mixture into a container for storage. I have these cute glass bottles, but a mason jar would work great as well!
Storage
Store your white mocha sauce in an airtight container in the fridge for up to two weeks. It can also be frozen for longer storage.
Top Recipe Tips
- Use good quality chocolate for the best flavor and texture. Avoid almond bark as that is usually low quality!
- You can find cans of sweetened condensed milk and evaporated milk in the exact sizes needed at the grocery store. Reference the recipe card for amounts. The sweetened condensed milk is the standard size can, while the evaporated milk is the smaller can size.
- Heat the sauce gently and stir frequently to avoid scorching. No need to boil!
- The sauce thickens as it cools. It should be pourable, even when refrigerated, but it can be reheated in the microwave, if needed.

Recipe FAQs
I opted for evaporated milk over heavy cream for a longer shelf life. Evaporated milk and sweetened condensed milk are shelf-stable, which helps the sauce last longer in the fridge compared to heavy cream, which can spoil more quickly.
Yes, you can make this white chocolate mocha sauce in the microwave! Simply combine the white chocolate, sweetened condensed milk, and evaporated milk in a microwave-safe bowl. Heat in 30-second intervals, stirring well after each round, until the chocolate is melted and the mixture is smooth. This usually takes 2-3 minutes, depending on your microwave. Once melted, stir in the vanilla, let the sauce cool slightly, and enjoy!
Starbucks typically uses the following number of pumps of white mocha sauce, depending on the drink size: Tall (12 oz): 3 pumps, Grande (16 oz): 4 pumps, Venti (20 oz hot): 5 pumps, Venti (24 oz iced): 6 pumps. Each pump is about 1 tablespoon, so you can adjust based on your preference for sweetness and richness.
