The last dairy/egg free cake I made for tea was this Vegan Lemon Cake Vegan Lemon Cake. It was nice and and almost all went at tea (my god son took the remainder home). If I didn’t have to be dairy and egg free I prefer a Mary Berry lemon cake, as I felt this tasted closer to a commercial lemon cake but it was perfectly acceptable for non Vegans (and was still far superior to commercial cakes) so I will be trying it again. My lemons were a little dry so I will retry with juicer lemons.
