Moist from sour cream and rich with coconut this cake is always a stand out on the dessert table at holiday parties and family gatherings.
Old-Fashioned Sour Cream Coconut Cake Recipe
This easy cake from a box mix is the next level for coconut lovers. While eating it you would never believe that it only takes 20 minutes to make.
Using defrosted frozen coconut means meatier pieces of tropical coconut and a restaurant quality cake. While flakes of coconut are nice in our Pineapple Cream Cheese Pie and Magic Cookie Bars, there’s something almost magical about the thicker pieces and fresh coconut flavor in this recipe.
The simple homemade frosting with sour cream is almost like making your own cream of coconut. Spreading this layer on top of the cake soaks in while refrigerating to make a super moist cake!
While it can be so hard to wait I do love cakes like this one and our Heath Bar Cake and Snickers Cake where time to soak up the rich goodness on top only makes them better!
Layer Cake vs. 9 x 13 Cake
We have made this as a round layer cake and in a 9 x 13″ pan. Since refrigerating is necessary we find that the 9×13 pan fits better in our refrigerator to store.
I have also had some trouble with the sour cream coconut frosting running to the center of the layer cake. This makes the center wonderful, but the outside edges don’t have the same level of moisture and flavor.
Ingredients Needed:
- Butter flavored yellow cake mix
- Eggs
- Butter
- Water
- Sour cream
- Frozen coconut
- Granulated sugar
- Whipped topping or Cool Whip
3 Day Sour Cream Coconut Cake
My original recipe is from an old community cookbook and the directions say to refrigerate for 3 to 4 days before eating.
While the cake is better after the sour cream mixture soaks in, we find this only takes a day or two. In our house the refrigerator space to store a cake that you can only look at for 3 days sounds pretty overwhelming! But if you have the will power to do this, know that it is totally acceptable!
Recipe Tips & Tricks
- I was able to find frozen coconut in bags in the bottom shelf of the frozen fruit section. You might have to check a couple different stores to find it, but it’s definitely out there!
- Dried shredded coconut flakes can be substituted for frozen coconut, but will have a different flavor.
- Allow cake to cool and chill if possible before adding frosting to prevent the frosting from becoming warm and flat right away.
- Refrigerate for a minimum of 4 – 8 hours before serving for best results. This will give the sour cream mixture time to soak into the cake and make it so much better!
Step-By-Step Instructions
Make cake batter according to the directions on the box. I use a Duncan Hines butter golden cake mix, so those are the directions that I follow.
Pour into a greased 9 x 13″ pan and bake until a toothpick inserted in the center comes out clean.
Bake cake and allow to cool.
In a separate mixing bowl stir together sugar, defrosted coconut and sour cream.
Once blended allow to chill.
Reserve one cup and spread the remaining portion of the mixture on top of the cooled cake.
Add the Cool Whip to the reserved cup of coconut mixture and blend well.
Carefully spread this mixture on top of the sour cream and coconut mixture. Cover pan with plastic wrap or a tightly fitting lid. Refrigerate for at least 4 hours.
Refrigerating overnight is better and will create a much more moist and delicious cake!
Serve chilled and enjoy the refreshing tropical taste of the Simple Sour Cream Coconut Cake!

Can you use flaked coconut in this recipe? Never heard of or seen frozen coconut, is the texture different? Thank you
Hey There! I was able to find frozen coconut in bags in the bottom shelf of the frozen fruit section. You might have to check a couple different stores to find it, but itโs definitely out there! Dried shredded coconut flakes can be substituted for frozen coconut, but will have a different flavor. I think the frozen coconut really makes this recipe special. Hope you enjoy ๐
So I’m confused about the frosting, is there two frosting. I mean you say put the frosting and put the second one mix with the whipped topping. Is it just one topping.
Hey There! Good question – there are two layers to the frosting. Mix up 3 ingredients & spread most of it on for layer 1 and reserve a cup to make layer #1. Then add Cool Whip to the reserved cup to make the thicker top layer.
Hope you enjoy ๐
can you freeze this cake after it has been frosted with coconut sour cream cream frosting and it has set for 4 days in refrigerator?
Hey There! We haven’t tested this, but I do think the integrity of the sour cream icing will decrease over time. I hope you enjoy the cake!
Hi! Iโve always used the sour cream , sugar , & frozen coconut with no problem . Lately the icing is too runny & I havenโt changed anything. I frosted the whole cake with this recipe without the cool whip , but now Iโm thinking I need something else to make it thicker so it will stay on the cake . So the cool whip Iโm guessing does this , right ? I donโt know if itโs the coconut or the sour cream has changed . Any suggestions?
