This may not be all that shocking for some, but for me it totally blew my mind. (Aside from the current state of our country and the world, of course.) The worst thing that could happen if you make this is that I was totally wrong, and that I’m just not a good judge of chocolate cakes and that the soy sauce is just too overpowering. Maybe I might not be as sensitive to soy sauce as others, being that I consumed a lot of it in my lifetime, but I honestly could not tell that this single 9-inch round cake contained any soy sauce, and a whopping 1/4th cup, at that.
But if you know you that 1/4 cup of soy sauce in this size of cake may be too much for you, decreasing it to 2 Tablespoons might be the way to go for you. And actually, when I tasted the cake 2 days later, I could in fact taste the soy sauce more. So in conclusion, if you intend to serve this on the same day it is made, use 1/4th cup of soy sauce, and if you intend to serve any of it a few days later, decrease the amount of soy sauce to 2-3 Tablespoons. And if you know that even a little soy sauce might not be your cup of tea, I think fresh brewed coffee would be an excellent substitute, or else just a little more sour cream.
