anyone have a good recipe for a dairy and soy free cake??

My DD has a milk/soy protein allergy and I am really missing my sweets! Her baptism is coming up in a week and a half and I am ordering a cake for it, but was thinking of also making a small cake so I can enjoy dessert as well!

I have seen some recipes online, but was hoping to find one that has been tested.

Usually I prefer to bake from scratch, but if anyone has any mix suggestions that are dairy and soy free I will take those as well!

TIA!!
