The Cake Mix Doctor’s Easy Refrigerator Coconut Cake

I remember the first time I tasted a truly remarkable coconut cake. It was at a summer potluck, hosted by a family friend known for her Southern hospitality. The cake, tall and gloriously white, beckoned from the dessert table. One bite, and I was transported: the tender crumb, the intensely coconut-y frosting, and the delightful moistness were unforgettable. I spent years trying to recreate that magic, and while I’ve come close with scratch recipes, this easy refrigerator coconut cake, inspired by The Cake Mix Doctor, captures that nostalgic flavor and texture with surprisingly little effort.

Recipe Overview

Prep Time: 25 minutes
Cook Time: 18-23 minutes
Total Time: 48 minutes
Servings: 12
Yields: 1 cake
Dietary Type: Not specified

Ingredients

18 1⁄4 ounces white cake mix (Duncan Hines is preferred)
1 cup milk
1⁄2 cup cream of coconut, plus more for brushing on the baked layers
3 large eggs

For the frosting:

2 cups sour cream
1 3⁄4 cups granulated sugar
1 (8 ounce) container frozen whipped topping, thawed
3 1⁄2 – 4 cups sweetened flaked coconut

Equipment Needed

Three 9-inch round cake pans
Vegetable oil spray
Flour for dusting
Large mixing bowls
Electric mixer
Rubber spatula
Wire racks
Sharp knife
Small brush
Serving platter

Instructions

Position a rack in the center of the oven and preheat oven to 350°F (175°C). Lightly mist three 9-inch round cake pans with vegetable oil spray, then dust them with flour. Shake out the excess flour and set the pans aside. This ensures the cakes release cleanly.
Stir the can of cream of coconut vigorously before opening to ensure the thick cream and thinner syrup are fully combined. This ensures an even coconut flavor throughout the cake and prevents just the syrup from being poured out.
In a large mixing bowl, combine the cake mix, milk, 1/2 cup cream of coconut, and eggs. Use an electric mixer on low speed until the ingredients are just incorporated, about 30 seconds.
Stop the machine and scrape down the sides of the bowl with a rubber spatula. Increase the mixer speed to medium and beat for 1 1/2 minutes longer, scraping down the sides of the bowl again if needed. The batter should look well blended and smooth. Avoid overmixing, which can result in a tough cake.
Divide the cake batter evenly among the 3 prepared pans, about 1 1/2 cups of batter per pan, smoothing the tops with a rubber spatula.
Place the pans in the oven. If your oven is not large enough to hold 3 pans on the center rack, place two pans on that rack and one in the center of the rack above. Keep a close eye on the cake on the upper rack, as it may cook more quickly.
Bake the cake until the layers are light brown and the tops spring back lightly when pressed with a finger, 18 to 23 minutes. The cake layer on the higher rack may bake faster, so test it for doneness first. A toothpick inserted into the center should come out clean.
While the cakes bake, prepare the frosting. In a large mixing bowl, place the sour cream and granulated sugar. Beat with an electric mixer on low speed for 1 1/2 minutes.
Stop the machine and scrape down the sides of the bowl with a rubber spatula. Increase the mixer speed to medium and beat until the sugar has dissolved, about 2 minutes longer. The mixture should be smooth and creamy.
Add the thawed whipped topping and beat on low speed until well blended. Stir in 3 cups of coconut and beat on low speed until just mixed. Be careful not to overmix at this stage, as it can deflate the whipped topping.
Place the frosting in the refrigerator to chill for at least 10 minutes. This allows the flavors to meld and the frosting to thicken slightly, making it easier to spread.
Transfer the cake pans to wire racks and let the cake layers cool for 5 minutes.
Run a sharp knife around the edge of each cake layer and give the pans a good shake to loosen the cakes. Invert each layer onto a wire rack, and then invert again so they are right side up.
While the cakes cool, use a small brush to gently brush the tops of the cake layers with the remaining cream of coconut. This will add extra moisture and coconut flavor.
Let the cakes cool completely, about 15 minutes longer. Cooling the cakes completely prevents the frosting from melting.
When the cakes are cool, use a large serrated knife to cut each cake in half horizontally to make 6 layers. This creates a taller, more impressive cake.
To assemble the cake, transfer one layer, cut side up, to a serving platter. Spread the top with a heaping 2/3 cup of frosting. Place another layer, cut side up, on top of the first layer and frost with 2/3 cup frosting. Repeat this process with the remaining layers and frost the top and sides of the cake. The cut side up ensures the brushed cream of coconut gets absorbed well.
Sprinkle 1/2 to 1 cup of coconut on top of the cake for garnish.
This cake can be stored in the refrigerator for up to one week.

Expert Tips & Tricks

For an even more intense coconut flavor, toast the coconut flakes lightly in a dry skillet before adding them to the frosting or using them for garnish. Watch carefully as they burn easily.
If you don’t have cream of coconut on hand, you can substitute with coconut milk, but the flavor will be less concentrated.
To ensure perfectly even layers, use a kitchen scale to weigh the batter before dividing it among the pans.
If you’re short on time, skip cutting the layers in half horizontally. The cake will still be delicious!

Serving & Storage Suggestions

Serve this coconut cake chilled directly from the refrigerator. It’s a perfect dessert for potlucks, parties, or any occasion where you want a crowd-pleasing treat. The cake will stay fresh in the refrigerator for up to a week, covered tightly. The flavors actually meld and improve over time, making it a great make-ahead dessert. Freezing is not recommended, as the frosting may separate upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I use a different size cake pan?

A: While 9-inch pans are ideal, you can use two 8-inch pans, but the baking time may need to be adjusted. Keep an eye on the cakes and test for doneness frequently.

Q: Why is it important to stir the cream of coconut before using?

A: Cream of coconut tends to separate in the can, with a thick, concentrated cream at the top and a sugary syrup at the bottom. Stirring ensures even distribution of flavor and consistency.

Q: Can I make this cake ahead of time?

A: Absolutely! In fact, the cake is even better after it sits in the refrigerator for a day or two, as the flavors meld together.

Q: The frosting seems too thin. What can I do?

A: If the frosting is too thin, try chilling it in the refrigerator for a longer period. You can also add a tablespoon of powdered sugar at a time until it reaches the desired consistency.

Q: Can I use unsweetened coconut flakes instead of sweetened?

A: Yes, you can use unsweetened coconut flakes, but you may want to add a bit more sugar to the frosting to compensate for the lack of sweetness.
