This delicious hot chocolate cake with a toasted vegan fluff topping is sure to be a favorite at this year’s Christmas parties!

Christmas is now 25 short days away! I’m still trying to figure out where the time has gone. Now is the time for you to decide which dessert you’ll be bringing to this year’s company Christmas party or dessert for an after Christmas dinner treat. This vegan hot chocolate cake is perfect for those occasions!

The peppermint extract that I added to the fluff makes me think of hot peppermint mochas from Starbucks (which is my go-to drink of the season). This recipe is the first time that I have used aquafaba in my baking. I am amazed at how well it works as an egg replacement or egg white replacement in this case. It whipped up so nicely that it has inspired me to see what else I can create with it! I’m seeing meringue desserts in my near future. The vegan fluff calls for using superfine sugar. I’ve left instructions in the notes section on how to make it if you don’t have any readily available.
