Learn how to make a Vanilla Sponge Cake using Gretchen’s Vegan Bakery’s recipe in this YouTube video. In the original video Gretchen explained some of the problems that cooks can encounter when baking the cake. There’s another video called How To Know When Your Cake Is Done Baking that may also help. The recipe is here: https://www.gretchensveganbakery.com/the-best-vegan-vanilla-cake-recipe/
Sorry if this isn’t quite what you expected but the video we’d found in 2015 was pulled from YouTube. Much more here on Gretchen’s YouTube Channel.
