I used 
Never baked with coconut flour before and I kept waiting for something to go wrong. It didn't. The cake came out dense and fudgy in a way I wasn't expecting from something with 2.4g net carbs.
Brought this to a dinner party last weekend. The friend who always has something to say about 'healthy' desserts went quiet after the first bite.
Ha. The quiet ones are always the best reviews. That cocoa base is rich enough that nobody's thinking about what's not in it.
We made this on a snow day last week because my kids wanted chocolate cake and I needed a project. My youngest has strong opinions about texture, refuses anything he calls "gummy," and when he came back into the kitchen asking where the rest went, I knew the crumb had worked. The almond and coconut flour combination gives it something more substantial than most keto cakes I've made -- closer to a real crumb than the flat density you sometimes get with almond-only recipes. My husband, who usually clocks the slightly-off quality that keto baking can carry, specifically asked whether we had more of the chocolate frosting left over. I did have to bake mine closer to 32 minutes to get the center set, so I'd watch it past the 27-minute mark. Planning to double the frosting next time.
Coming back asking where the rest went, that's it. I check at 28 because it varies by oven. Double the frosting, yes.
