Maybe go to a different flavor of coconut flour cake, such as.... coconut ? add coconut extract and flaked coconut, plus the vanilla, and then just use chocolate icing ? Maybe try a different brand of cocoa powder? Or carob powder icing ? Or use mashed banana in the cake batter ?
Don't give up, everybody has made something they thought was pretty good and then ..... the reaction. Then you feed the leftovers to somebody else.
I am going to try another brand of cocoa powder or go with carob instead. And I've become very pessimistic about coconut flour in general because it is so extremely finicky. I tried making muffins with it the other day and they turned out a soggy mess. Not to mention the taste was absolutely horrible; could not get it down. And the smell was equally bad.
You could also try making a cake with a different set of flours. There are gluten free
cake mixes out there. You can also bake from scratch gluten free with rice flour,
sorghum flour, all kinds of flours. This will result in a cake more like what you're
used to. It's entirely possible you're just intolerant to coconut......
Perhaps, but the starchy flours are too high on the glycemic index for me. I need something lower in carbs. Gonna try almond flour next time.
