Recipe Request for Gluten Free Vegan Chocolate Cake with Whipped Chocolate

I have been using this recipe for years and am trying to remember the website I sourced it from so they get the credit, but I’m seeing this exact recipe across many sites, so it may be futile. What is a guarantee is that this recipe works as a cake or as cupcakes. As a cake, it fits in a 9x9 pan - I always line the bottom, and it is important to let it cool before you turn it out.

UPDATE: the recipe comes from the cookbook Vegan Cupcakes Take Over The World and the link from their website is here:

The whipped chocolate comes from a technique by Chef Herve This
