White Chocolate Fudge Sauce

This white chocolate fudge sauce, with little flecks of vanilla seeds throughout, is wonderful drizzled over ice cream or cakes, or in sandwich cookies.

This post is sponsored in conjunction with #SpringSweetsWeek. I received product samples from sponsor companies to help in the creation of the #SpringSweetsWeek recipes. All opinions are mine alone.

This hot fudge sauce, made with vanilla, white chocolate, and homemade marshmallow creme is easy to make and perfect for an ice cream sundae party. It's easy to make ahead and reheat when you are ready for dessert. 

Plus, I'm giving you a bonus recipe for homemade marshmallow creme, which you can use to make Fluffernutter sandwiches, add to coffee or hot chocolate, top banana splits, or even as a filling for macarons

Ingredients in this Sauce:

Homemade Marshmallow Creme: This marshmallow creme is gelatin-based rather than meringue-based. It's also flecked with vanilla seeds from vanilla bean paste from one of our prize sponsors, Taylor & Colledge

It's also flavored with sea salt flakes from another prize sponsors, Selefina Spices. I'm so excited to have been introduced to their products. The quality is amazing. Plus, they have so many choices in sample sizes

You can either use light corn syrup or honey in the mix. If you use honey (which I did), just know that there will be a faint honey flavor. 

For the Fudge:

White Chocolate: You can use a white chocolate candy bar or baking chocolate. 

Honey or Light Corn Syrup. 

Heavy Cream.

Sea Salt Flakes

Vanilla Bean Paste with Seeds

Note: This recipe was adapted from Taylor & Colledge, one of our sponsors. They have so many wonderful recipes on their site.

Equipment You May Need:

You will need either a stand mixer or a hand mixer. I recommend a stand mixer because you will be beating the marshmallow creme mixture for at least 15 minutes. 

The most time consuming part of making this sauce is making the marshmallow creme. If you don't have the time, feel free to use store bought. 


You can make the marshmallow cream up to 30 days in advance and keep it in the refrigerator. 

The hot fudge sauce will keep in the refrigerator for at least a week and is easily reheated in the microwave.

Additional Tips:

Corn syrup (or glucose syrup, which you can find in craft stores) versus honey. For a stronger vanilla flavor, use corn syrup or glucose syrup. If you use honey, you will definitely taste it. I really enjoyed the honey flavor but it was definitely distinct. 

When cooking the marshmallow creme, be sure to use a pan large enough to handle the expansion of the mixture. It will bubble up quite a bit. If it still bubbles up too much, just lower the heat a bit and stir the top of the bubbles to keep them from overflowing.
