🍰 How to Make Easy Coconut Cake Using Box Cake
Follow these simple steps to turn boxed mix into bakery-style coconut perfection!
Step 1: Prep Your Pans & Preheat Oven
Preheat your oven to 350°F (175°C). Grease and flour your cake pans or line with parchment paper for easy release. This helps avoid sticking and ensures clean layers.
Step 2: Mix the Cake Batter
In a large bowl, add the cake mix, coconut milk, oil, egg whites, and coconut extract. Use a hand or stand mixer to beat on low for 30 seconds, then on medium speed for 2 minutes until smooth.
Gently fold in the shredded coconut with a spatula. This gives the cake that classic coconut texture.
Step 3: Bake the Cake
Pour batter evenly into prepared pans and bake for 25–30 minutes (round pans) or 30–35 minutes for a 9×13″ pan. The cake is done when a toothpick inserted in the center comes out clean.
Remove from oven and let cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
Step 4: Make the Frosting
Beat the cream cheese and butter together until creamy. Slowly add in powdered sugar 1 cup at a time, then mix in coconut extract and coconut milk to reach a spreadable consistency.
💡 Want a lighter option? Use stabilized whipped cream or coconut whipped topping.
Step 5: Frost and Decorate
Once cakes are completely cooled, spread frosting between layers, on top, and around the sides. Press shredded coconut into the frosting all around the sides and top for that classic snowy-white look.
Refrigerate for at least 30 minutes before slicing for clean layers.
🔄 Variations
Coconut cake is super versatile! Try these variations to switch it up:
1. Pineapple Coconut Cake
Add ½ cup crushed pineapple (drained) to the batter or between layers for a tropical twist.
2. Lime Coconut Cake
Add lime zest to the batter and lime juice to the frosting for a zesty flavor.
3. Toasted Coconut Topping
Toast your shredded coconut in the oven at 350°F for 5–7 minutes until golden brown for added crunch and a nutty aroma.
4. Coconut Poke Cake
Bake the cake in a 9×13” pan, poke holes all over, and pour sweetened coconut cream or condensed milk on top before frosting.
5. Bundt Version
Use a greased Bundt pan and bake for 45–50 minutes. Glaze with coconut icing and sprinkle with coconut.
📌 Cooking Notes
- Don’t overmix: Mix just until the batter is combined to keep the cake soft.
- Use room temperature ingredients: This helps everything blend smoothly and evenly.
- Cool fully before frosting: Warm cake will melt your frosting.
