Hot Fudge Homemade Marshmallows

Hot Fudge Homemade Marshmallows are delicious! They are wonderful to add to hot cocoa, eat alone or eat toasted. They are just perfectly wonderful! 

If you’ve been around our blog at all this year, you have seen that I’m on an adventure with homemade marshmallows. I have really enjoyed coming up with new flavors. At the bottom of this post you can find all the flavors I’ve made. A few included in that list are mocha marshmallows, gingerbread marshmallows and s’mores marshmallows.

After making the s’mores marshmallows, I thought just hot fudge alone would be so good. The s’mores marshmallows are delish, but they aren’t great in hot cocoa because the graham crackers get really soggy. But Hot Fudge Homemade Marshmallows are so good in hot cocoa. They add just a little over the top flavor. They are also good toasted or even just pop one in your mouth after they are set.

Like all the marshmallows I’ve made, these are super simple and easy to make. Every time I make marshmallows, I am amazed how whipping air into sugar makes it a brilliant white and it becomes so fluffy. It’s like magic. 

I would have never guess that whipping a clear liquid for a long time would make it bright white. It’s amazing how God creation works. I think He’s just as delighted as we are when He sees us create new things from what He’s created.  And then fold hot fudge into it makes it even more delicious.
