So it turns out that this vegan version of love cake takes a little longer to bake to brown up, but otherwise, it seems to work just fine! I’m happy with the texture, which is the important thing that was worrying me.
I want to try another variation (using egg replacer instead of bananas & aquafaba) before I settle on something final for the cookbook, but this is totally acceptable. It’s a little bit like a cross between banana bread and love cake. Interesting!
