Moist Coconut Cake from a Box Mix
This coconut cake starts with a box of mix and comes out soft, fragrant, and full of little coconut flecks. It is the kind of dessert that looks like a project but comes together with almost no measuring.
A quick coconut milk glaze soaks into the warm cake and gives it a tender crumb and a gentle sweetness. You do not need a mixer, and the whole thing tastes like you went to far more trouble than you actually did.
Why This Coconut Cake Stays in My Recipe Box
The crumb stays moist for days because full-fat coconut milk replaces some of the oil and keeps the batter rich. It is the one swap that makes a box mix taste homemade.
Each bite has chewy bits of sweetened shredded coconut tucked inside, so the coconut flavor does not just sit on top. The glaze is stirred together in a bowl while the cake bakes, and you pour it on while the cake is still warm so it soaks right down into the surface.
This is the version I reach for when I want a tropical dessert that does not stress me out. It works every time, and the leftovers stay tender longer than any other cake I make from a mix.
Ingredients
- 1 box (15.25 oz) white cake mix: look for a brand that does not have pudding in the mix for the lightest crumb
- 4 large eggs: room temperature eggs blend in more evenly
- 1/2 cup vegetable oil: or any neutral oil
- 1 cup full-fat coconut milk, well shaken: the fat is what gives the cake its soft texture
- 1 cup sweetened shredded coconut: plus a little extra for the top
- 1 cup powdered sugar: for the glaze
- 2 to 3 tbsp coconut milk: a small amount for the glaze, added slowly
- 1/2 tsp vanilla extract: rounds out the glaze
Easy Swaps and Add-Ins
- Swap the oil: melted coconut oil gives a stronger coconut taste, but the cake will firm up when chilled so bring it to room temperature before serving.
- No coconut milk handy: use regular whole milk and add 1 tsp coconut extract to the batter.
- Dairy-free: most white cake mixes are already dairy-free, and you can use coconut oil instead of vegetable oil.
- Mix-ins: fold in 1/2 cup chopped macadamia nuts or white chocolate chips for extra crunch.
If you like tropical cakes, my pineapple upside-down cake is another low-effort favorite.
How to Make Moist Coconut Cake from a Box Mix
Step 1: Mix the Batter
Preheat the oven to 350°F (175°C) and grease a 10-cup Bundt pan thoroughly with butter or nonstick spray. In a large bowl, whisk together the 4 eggs, 1/2 cup oil, and 1 cup coconut milk until smooth. Add the cake mix and 1 cup shredded coconut, then stir with a wooden spoon or spatula just until no dry streaks remain.
The batter will be thick and dotted with coconut. Overmixing right now can make the cake tough, so stop as soon as everything looks combined.
Step 2: Bake the Cake
Scrape the batter into the prepared pan and smooth the top. Bake for 40 to 45 minutes, until the edges pull away from the sides and a toothpick poked into the center comes out with a few moist crumbs. Let the cake cool in the pan on a rack for 10 minutes, then invert it onto the rack and lift the pan off.
If you peek through the oven door near the end, the top will be deeply golden and the kitchen will smell like toasted coconut. Resist the urge to open the door too early, or the cake might sink in the middle.
Step 3: Whisk the Glaze
While the cake cools slightly, whisk 1 cup powdered sugar, 2 tablespoons of the reserved coconut milk, and the vanilla in a small bowl. The glaze should be thick enough to coat the back of a spoon but still pourable. Add the remaining tablespoon of coconut milk only if it seems too stiff.
You want a glaze that will cling to the warm cake and set into a thin, crackly layer. It thickens quickly, so make it right before you plan to use it.
Step 4: Soak and Glaze the Warm Cake
Place the cooling rack with the cake over a sheet of parchment or a baking sheet to catch drips. Spoon the glaze over the top of the warm cake, letting it run down the sides. Scatter a little extra shredded coconut over the glaze before it sets. Let the cake cool completely so the glaze firms up, then slice with a serrated knife.
The knife will glide through the soft crumb, and the white shreds of coconut inside will look bright against the yellow cake. Serve the slices on a plain plate so the glossy glaze stands out.
Tips for a Box Mix Cake That Tastes Homemade
- Shake the can of coconut milk hard before measuring. The cream separates from the water, and you need the fat for a tender cake.
- Grease the Bundt pan with a pastry brush so you can reach into every crevice. A dusting of flour over the butter helps the cake release cleanly.
- Toast the shredded coconut in a dry skillet for 2 minutes before stirring it into the batter if you want a more intense coconut taste.
- If you do not have a Bundt pan, a 9×13-inch pan works too, just shorten the bake time.
Bake times by pan:
| Pan Type | Size | Bake Time |
|---|---|---|
| Bundt pan | 10-cup | 40-45 mins |
| 9×13-inch pan | standard | 30-35 mins |
| Loaf pans (2) | 8×4-inch | 45-50 mins |
Keeping the Cake Fresh
- Refrigerate: Store the cake in a covered container at room temperature for up to 2 days, or in the fridge for up to 4 days. The coconut milk keeps it from drying out.
- Reheating: A quick 10-second zap in the microwave brings back that just-baked softness, especially if you skip the glaze and want a warm slice.
- Freeze: Wrap individual slices tightly in plastic and freeze for up to a month. Thaw them on the counter for an hour.
Frequently Asked Questions
Can I use coconut cream instead of coconut milk?
Yes, but coconut cream is thicker and higher in fat. Thin it with a splash of water until it reaches the consistency of regular coconut milk, or the cake may turn out heavy.
Why did my cake stick to the pan?
Most Bundt pans need a thorough greasing with softened butter or a solid nonstick spray, and a light dusting of flour helps even more. If you missed those steps, cool the cake upside down for 15 minutes and gently tap the pan to loosen it.
My cake turned out dry. What went wrong?
It likely overbaked. Check it 5 minutes before the low end of the range, and pull it when a toothpick comes out with a few moist crumbs, not completely clean. Also, make sure you measured a full cup of coconut milk, as less liquid can dry out the crumb.
Can I skip the glaze for a less sweet cake?
You can, but the glaze adds most of the coconut flavor that soaks into the top. If you leave it off, dust the cake with a little powdered sugar and serve it with fresh pineapple or whipped cream.
