That link has a bunch of annoying pre-recipe text so if you want just the recipe, use this link: https://lovingitvegan.com/vegan-oreo-cake/print/11083/
The cake turned out great, it tasted really nice. Definitely the best cake we've made yet. Texture was actually like a cake and it wasn't hard. However, it was pretty dry but I'm not sure what can be done to fix that. I also think it felt like too much chocolate so if you're not into that I'd recommend getting rid of the cocoa powder for the cake itself and making it more vanilla-ish. The icing does the trick for chocolate anyway.
