Curious why you can’t make something not vegan for the group, and have something different for her… or would she be offended?
(FYI most Indian breakfasts are vegan by default (if you think something indian would fly). There are some savory steamed and baked cakes that are delicious, polenta-like dishes, savory crepes / pancakes, and more.)
Honestly, I’d recommend any of the recipes on Rainbow Plant Life (I’d link you, but I’m new here, so I’m afraid you have to google it.)
Nisha Vora, the writer of those recipes, is some kind of cooking wizard-- every time I make one of her dishes, I have a table full of omnivores begging me for the recipe. I’ve personally made her pumpkin sheet pancakes, which is not exactly what you asked for, except the first time I made them I didn’t have a sheet pan large enough, baked them twice as long, and ended up with sort of… squishy pumpkin bars?
As for why you can’t find a vegan baking thread, there are a couple of reasons. Firstly, you might not be searching buzzwords: a lot of businesses are branding themselves plant-based instead of vegan in the last few years for image reasons. Second, a lot of baked goods are incidentally vegan, especially breads, so a lot of people don’t bother/think to label them. And frankly, even if you did find a vegan baking thread, there are a lot of vegan baked goods that I think are just awful-- oversweet or with a questionable texture because someone decided to lump together their obligatory gluten-free and vegan option.
