Incredibly delicious, super moist, Coconut Sheet Cake topped with a perfect Coconut frosting.

Coconut Sheet Cake

As any good potlucker knows, you can’t just bring any dessert to a potluck. There’s a trick finding the right recipe, a balance that has to be just right. You want something that can easily be made into a large batch. But you also want something that will be popular enough (read: delicious enough) that you don’t take a bunch home. (The last thing I need in my life is to bring home two pans of brownies.) Today’s recipe is a perfect fit. This coconut sheet cake is easy to make and serve, while simultaneously being absolutely, soul-filling-ly delicious.

I’ve always loved the simplicity of sheet cakes. It’s as easy as making the batter, spreading, cooking, and adding frosting. However, sometimes sheet cakes can end up too dry and crumbly. It’s an unfortunate side effect of making a cake so thin.

But this coconut sheet cake is moist—I mean really, really moist. It’s definitely a “melt in your mouth” kind of treat. But sometimes moist cakes are too light, and you don’t feel like you’re actually getting much cake with each bite. This cake isn’t like that at all. It’s both moist and dense. Every forkful of this delicious sheet cake will taste full and sweet. Don’t even try to resist two slices

This is a cake for those with a sweet tooth. I would describe it as “very sweet.” The shredded coconut on top pairs really nicely with the sweet cake and frosting. It also helps to cut that sweetness down a little. Don’t skip it!

A great way variation that will fancy-up this cake adding fresh fruit as a topping. Raspberries especially taste wonderful with the shredded coconut already on top. Just go to your local grocery store/farmer’s market and pick up a container of fresh raspberries. Then, top every slice. It’s that easy.

Recipe Notes:

Using eggs that are a room temperature is a good idea. This is so there’s much less chance of them cooking when added to the saucepan.

The sour cream in this recipe is a really nice ingredient. It does a lot to help sure everything binds together in that dense, moist cake texture you want. I go ahead and use full fat sour cream. The full fat adds a really nice (and necessary) richness that helps to balance out this very sweet cake.

When you’re completed the batter, don’t worry. It’s supposed to look like that. This recipe makes a really runny batter. This is not a mistake. In fact, it’s part of what gives this cake its awesome texture.

Make sure you use a full 10 x 15 pan. Trying to use a 9 x 13 won’t work. The cake will not cook properly.

It is important to cook this cake through all the way. A cake with this moist of a texture won’t stay together—or taste very good—undercooked. Cook the cake until the top has a nice golden color. The old toothpick method will help here as well. Just insert a toothpick into the very center of the cake. If it comes out completely clean, then your cake is cooked through.
