Via google, I found this recipe but haven't tried it myself (can't cook or bake). Have you seen this before?

All my daughter's sophisticated friends LOVED this birthday cake. It
came wondrously close to the devil's food cake my mother used to make
from the 1922 Fanny Farmer cookbook--a taste that has remained like
Proust's madeleine in my memory of all that is wonderful about having a
birthday. I made it in a Vitamix. I'm sure any blender would do as well,
or do it by hand.
4 eggs
1/2 c. shortening (I used Crisco for the first time in a cake!!)
1 1/2c. buttermilk or sour milk (for non-dairy: I used 1 1/2 c.
water plus 3/8 c. soy powder and 2 tsp. cider vinegar)
1 tsp gf vanilla extract (or use vanilla'd sugar)
1 1/2 c. sugar (this is too much for my taste; I use about 1 c of
vanilla sugar, i.e., sugar in which a vanilla bean has been
basking)
1/2 c. cocoa
1 1/2 tsp baking soda
1/2 tsp baking powder (use 2 tsp if you use non-wheat flour)
1/2 tsp Xanthan gum
1/2 tsp salt
3/4 c. corn starch, 1/4 c. potato starch, 1/3 c.
each of peanut (or other nut flour) and sweet potato
flour. (Total of 1 and 2/3 cups flour)
Place eggs, shortening, buttermilk, vanilla, sugar and cocoa in
blender. Blend 'til light and fluffy. Stop machine, add other dry
ingredients, and blend, or mix in a bowl.
Bake till done (depending on the size and shape of the pan at 350
in a generously greased and floured pan.
I used a simple glaze of orange juice and confectioner's sugar.
