White Chocolate Sauce Recipe for Coffee
Ingredients with Tips

2 cups white chocolate chips – Using good quality white chocolate chips makes a big difference in how your sauce turns out. Cheaper white chocolate can taste overly sugary or slightly waxy, so it’s worth picking a brand that lists cocoa butter as one of the first ingredients
1 cup whole cream milk – Heavy cream milk gives the richest, smoothest texture, but if you want a slightly lighter sauce you can use half and half works fine
2 tablespoon vanilla flavor – If you enjoy a deeper flavor, adding a small amount of vanilla bean paste instead of regular vanilla extract gives the sauce a more natural, bakery style taste.
30g of unsalted butter
A pinch of salt

Variations and Substitute
Once you’ve mastered the basic white chocolate sauce recipe, you can easily switch things up to create new flavors. Here are some simple variations you can try at home.
Heavy Cream
Add 1 cup or half a cup heavy cream with the milk. This gives the sauce an extra rich and smooth that is thicker like a proper ganache. It’s great as a topping for cheesecake or as a rich drizzle over an iced latte or iced mocha.
Raspberry
Stir in a spoonful of raspberry syrup while the sauce is still warm. The sauce will turn out to be a pinkish white chocolate sauce that’s perfect for drizzling Iced latte or hot coffee, ice cream, or even it could be use for Iced rose latte.
Matcha
Add in half a teaspoon of matcha powder while the sauce is warm for a matcha white chocolate flavor. This variation is great for making a matcha iced latte with a flavor of white chocolate in it or as a drizzle over cakes and cookies.
Peanut Butter
You can stir in a spoonful of peanut butter once the white chocolate chips have melted into the milk. This creates a rich, nutty white chocolate peanut butter sauce that works well as a dip for fruit or a topping for ice cream.
Ways to Use This Delicious Ganache
This white chocolate sauce works as more than just a coffee syrup. Add a spoonful to your hot or iced coffee and for a homemade white mocha, or you can even add it to steamed milk for a white hot chocolate.
It also makes a wonderful dipping sauce for fruit, and a rich drizzle over cakes, brownies, or ice cream. Because the texture is similar to a light ganache, you can use it as a topping for cheesecake or as a glaze over cookies.
If you enjoy trying different flavors, this same method can be adjusted to make other syrups, like a coffee syrup or flavored drizzle for pancakes and waffles.
Kitchen Tips
For the smoothest sauce, melt the white chocolate slowly and avoid high heat, since white chocolate can seize or turn grainy if it gets too hot too quickly.
If your sauce turns out too thick, warm it gently and stir in a small splash of cream until it loosens up.
If it’s too thin, let it sit in the fridge for a bit longer so it firms up naturally.
Always taste as you go, since white chocolate brands vary in sweetness, and you may want to adjust the amount of vanilla or salt to balance the flavor.
Storage options
Once your white chocolate sauce has cooled, transfer it into a sealed jar or airtight container and keep it in the fridge. It can stay fresh for about 1 to 2 weeks. The sauce will thicken while refrigerated, so you may need to reheat it, let it warm at room temperature, or place the jar in a bowl of warm water.
