This Easy Coconut Sheet Cake with a coconut cream cheese frosting is nothing short of decadent. It starts with a boxed mix and ends with a moist, delicious, melt-in-your-mouth coconut cake!

If you’ve ever wanted homemade coconut cake but with less hassle – THIS IS IT. By doctoring up a boxed mix with sour cream, pudding mix and coconut extract, you’ll have a moist and spongy coconut cake. Slather it with my easy cream cheese frosting for the ultimate dessert for coconut lovers!

Every week for a month or so now, I’ve been getting a slice of coconut sheet cake from my local grocery store’s bakery while grocery shopping. The other day they were sold out, so I decided to take matters into my own hands.
I went to my Cranberry Pineapple Upside-Down Cake recipe for inspiration because it also uses a boxed mix (and is incredibly delicious!). I changed a few things up and was extremely happy with the outcome.
Ingredients Needed

- Boxed cake mix – You’ll need a 15.25 ounce white cake mix.
- Pudding mix – A 3.4 ounce package of instant coconut cream pudding mix.
- Sour cream – Adds moisture to the cake.
- Vegetable oil
- Eggs – Please see the notes below about using egg whites vs whole eggs.
- Coconut extract
- Water
- For the frosting – Cream cheese, butter, powdered sugar, coconut extract, and sweetened flake coconut.
Using Egg Whites vs Whole Eggs
White cake mixes call for egg whites because using the yolks gives the cake a yellow color. Since this recipe uses coconut cream pudding, the cake will still have a slight yellow color despite using egg whites.
I tested this recipe using three whole eggs in one cake and four egg whites in another. The result was that the cake with whole eggs tasted the same but had a slightly darker yellow color.
In the photos shown in this post, I used egg whites on the cake. Basically, it doesn’t matter if you use whole eggs or egg whites—it’s delicious either way!
