👩🍳 How To Make Coconut Cake Recipe With Cake Mix?
1. Preheat the Oven
I start by setting my oven to 350°F (175°C) and lightly greasing my baking pan. A little dusting of flour helps too.
2. Mix the Batter
In a large mixing bowl, I combine the white cake mix, coconut milk, oil, eggs, sour cream, and coconut extract. I beat the mixture for about 2 minutes until it turns smooth and fluffy. Then, I fold in the shredded coconut gently.
3. Bake the Cake
I pour the batter evenly into my prepared pan. I bake it for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Once baked, I let it cool completely on a rack.
4. Make the Coconut Frosting
While the cake cools, I beat softened butter until creamy. Then I gradually add powdered sugar, coconut milk, coconut extract, and a tiny pinch of salt. I keep beating until the frosting turns light and fluffy.
5. Frost and Top
After the cake cools, I spread the frosting evenly and sprinkle the top with extra shredded coconut. Sometimes I even toast the coconut for a little crunch.

🍽️ Serving Suggestions
I love serving this coconut cake:
- Cold, straight from the fridge on summer days
- With fresh berries like raspberries or strawberries
- Alongside a warm cup of chai or black coffee
- With a scoop of vanilla or coconut ice cream for dessert night
💡 Tips and Variations
My Best Tips:
- Use room temperature eggs and sour cream for a smoother batter.
- Don’t overmix after adding coconut flakes. Keep it light and airy.
- Chill the frosting for 15 minutes if it feels too soft to spread.
Easy Variations:
- Swap white cake mix with yellow cake mix for a richer flavor.
- Add crushed pineapple (drained) for a piña colada twist.
- Use cream cheese in the frosting if I want a tangy contrast.
- Toast the shredded coconut before sprinkling—it adds a nutty depth.
🌿 Health Benefits
While this is a dessert, coconut offers some natural perks:
- Coconut milk contains healthy fats that may support metabolism.
- Shredded coconut adds fiber to help with digestion.
- The moderate use of sour cream and eggs boosts protein and B vitamins.
That said, it’s still a sweet treat, so I enjoy it in moderation.
📝 Note
If I’m short on time, I sometimes use store-bought coconut frosting and just sprinkle extra shredded coconut on top. But trust me—this homemade version tastes so much better.
❓FAQ: Coconut Cake Recipe With Cake Mix
Can I use yellow cake mix instead of white?
Yes, I’ve tried it myself. Yellow cake mix gives a richer, buttery flavor. Just know the cake will have a slightly deeper color.
How do I store leftover coconut cake?
I always store mine in an airtight container in the fridge. It stays fresh for up to 5 days. I like it even more the next day because the flavors settle beautifully.
Can I freeze this cake?
Absolutely. I wrap individual slices in plastic wrap and freeze them in a zip-top bag. They last up to 2 months. I thaw them in the fridge overnight or microwave them gently.
What can I use instead of coconut milk?
When I don’t have coconut milk, I use whole milk mixed with 1/2 teaspoon of coconut extract. It keeps the flavor close without changing the texture.
How can I make the cake more moist?
I always add sour cream to boost the moisture. You could also mix in a tablespoon of mayo—yes, mayo! It sounds strange, but it works wonders.
Can I toast the shredded coconut?
Yes, and I highly recommend it. I toast mine in a dry skillet over medium heat for about 3–4 minutes, stirring constantly. It adds a lovely nutty crunch and golden color.
Is this recipe good for cupcakes?
Definitely. I’ve made about 24 standard cupcakes from this recipe. Just bake them at 350°F for around 18–20 minutes.
Do I need to refrigerate the frosting?
If I make it ahead of time, yes. I keep the frosting in the fridge for up to 3 days and bring it to room temperature before spreading it.
🔚 Conclusion
Making a coconut cake with cake mix is one of my favorite baking shortcuts. It’s quick, foolproof, and always a hit at gatherings. I love how the boxed mix gives me a reliable base, while the coconut milk, sour cream, and extract bring in that island flavor.
This recipe proves that a little creativity can turn a simple mix into something that tastes homemade and full of love. If you’re a coconut fan like me, give it a try. I bet you’ll make it more than once.
