Fluffy & Moist Coconut Cake

I was craving coconut cake and had 5 egg whites taking up space in my fridge so this is the recipe I settled on (and because Sally's recipes are great). This cake delivered! Fluffy and moist for sure! Between each coconutty cake layers I spread a layer of lime curd (allrecipes) and frosted the cake with ermine frosting. I did replace the sour cream with Greek yogurt (thinned with a bit of milk) and used unsweetened coconut in the cake - it was still plenty sweet and perfectly moist. I baked in 3 6 inch cake pans for about 28 minutes or so.
Update 4/27 I continue to love this recipe - usually pair with lime or lemon curd (Stella Parks Recipe is great if you can find it) and Ermine frosting (most recently sugarspunrun recipe).
