I'm looking for the best coconut cake recipe. Non-traditional coconut cake would be great--Maybe with chocolate?? I need suggestions, please!!

Have you tried Coconut carrot cake ?

Here you go! This is my most requested cake, and one of the most popular here on Food52. https://food52.com/recipes/22096-omg-coconut-pound-cake?from_feed=1

Thank you so much, everyone, for your fabulous suggestions! I am going with the RLB coconut cake, using the frosting from Joanne Chang. I'm going to toast shredded coconut for the top, and then I'm going to crush up nice dark chocolate for the final topping. :) I'll let you know how it turns out!

Stella Parks, who contributes to Serious Eats, just wrote a recipe for Coconut Cake. It looks amazing!

Have you tried this one? https://food52.com/recipes/22091-coconut-tres-leches
So good!

I once made a coconut cake that I filled with a passionfruit curd, and frosted with whipped cream that I'd included some coconut milk in. It was great! I used this cake recipe from Joanne Chang: http://cackalackyfoodie.blogspot.com/2011/03/birthday-coconut-cake-and-neglecting.html

and this recipe for passionfruit curd: http://www.foodandwine.com/recipes/six-layer-coconut-cake-passion-fruit-filling

What about a Hummingbird Cake? Ben Mims has a delicious version.

For layer cakes, I personally like to take simple, reliable recipes and put them together in unique ways...so instead of looking for a "chocolate coconut cake", I'd take a fabulous coconut cake and find a way to incorporate a chocolate component in the layering process, like a ganache or a chocolate buttercream, and then find a way to throw more coconut in there since chocolate has a pretty dominating effect.

If it were me....I'd bake that RLB coconut cake, because she's amazing....and then fill it with a chocolate ganache, frost it with a 7 minute frosting and cake it with toasted coconut....but that's me...and I tend to be extra.

I've made Ina Garten's cake several times successfully. Do read the comments, though, in case you have preferences. Happy b'day to your partner.

Not chocolate, but from Rose Levy Beranbaum (of Cake Bible fame) and Southern Living magazine (region which loves coconut cake):

Tartine bakery has a coconut tres leches cake. Full disclosure: I haven't made it yet so I don't know if it's the best coconut cake, but it sounds really good. http://www.baketard.com/blog/2011/7/12/tartines-pastel-de-tres-leches-cake.html
