We experimented and made ube cake. We purchased the ube extract and powder online and used betty crocker gluten free yellow cake mix as the base. It has a pretty purple color and the taste was ok – not great, not bad. We think making it gluten free with the yellow cake mix might have affected the flavor more than we expected.
Here’s what it looked coming out of the oven. The top didn’t change at all after baking. We topped it with white buttercream frosting. Not weight loss friendly!
