When I was in 9th grade, we read a book in which the main character eats a lavender cake. I cannot remember the book, though I'm pretty sure it was 18th/19th century English Literature a la Jane Eyre. The teacher brought us all a piece of lavender gum so we could experience what it was like to eat lavender (there were probably 200+ students in all of her sections, I went to a very large high school, so one piece of gum was really all that was reasonable).
Anyway, that piece of gum did not even come close to replicating the taste of fresh lavender gently baked into a light and delicate cake:
This vegan version by Vegan Treats is amazing. It's covered in white chocolate and has the perfect amount of lavender.
