Coconut Sheet Cake


Why do I keep making big cookie sheet pans full of cake to tempt me all day long?? It just seems right, that’s why. And still I have plans to make more…because now that I’m suddenly obsessed with sheet cakes I need to try all the flavors! Don’t get me wrong I’ve always loved sheet cakes but I’m just now really appreciating the fact of their simplicity. Mix it, spread it, bake it, frost it, boom done! They’re just easier than layer cakes yet they can still be fancied up, they don’t need to just be your average potluck sheet cake.

This time around I was feeling like coconut cake, so Coconut Sheet Cake it is! And this one most definitely does not disappoint! We were all trying to resist two slices but it’s just not possible with this cake, it’s just not, don’t judge – you’ll see :). At least I waited a few hours to go back for more (as if that helps lol). What I’m getting at is that you need to try this cake! If you like coconut this is the cake for you, and once you try it you’ll want to make it for every get together and special occasion that comes your way. It’s has a perfectly soft and moist crumb and you will be savoring every last bite of it. And don’t get me started on the coconut and fresh raspberry combo, this cake is just that much better when it’s topped with fresh raspberries! Then last but not least, I can’t forget to mention how much love with this Coconut Cream Cheese Frosting, it is one of the dreamiest things on the planet! It’s total bliss in frosting form. Yeah, this cake is a diet killer but it’s worth it!

  • Suhaila: Thanks for this recipe :) this cake was such a crowd-pleaser and I look forward to making it again!

    Sadly I couldn’t find coconut extract anywhere so I replaced it with coconut cream. Also used a standard round cake pan because it’s all I had, it took longer to bake but still worked. June 25, 2018 at 3:49am Reply
