Sticky Coconut Cake Ingredients
Here’s everything you need to make this delectable Sticky Coconut Cake!
For the Batter
• Eggs (2, separated) – Provide structure and moisture; substitute with aquafaba for a vegan version.
• Granulated Sugar (1¼ cup) – Adds sweetness and helps create a golden crust.
• Full-Fat Canned Coconut Milk (2¼ cup) – Gives richness and enhances the coconut flavor; remember to shake well if it separates.
• Shredded Sweetened Coconut (3 cups) – Imparts intense coconut flavor; use unsweetened coconut for a less sweet treat.

• Vanilla Extract (1 teaspoon) – Enhances overall flavor, optional for added variations.
Step‑by‑Step Instructions for Sticky Coconut Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This crucial step ensures your oven reaches the perfect baking temperature for your Sticky Coconut Cake, which allows the cake to rise beautifully and develop a golden crust. Prepare an 8×8-inch baking pan by greasing it lightly with oil or lining it with parchment paper for easy removal later.
Step 2: Whisk the Egg Whites and Sugar
In a medium mixing bowl, vigorously whisk the separated egg whites and granulated sugar together using a handheld mixer or a whisk. You should aim for a mixture that is frothy and well combined, which usually takes about 2-3 minutes. This step incorporates air into the mix, ensuring a light and fluffy texture for your cake.
Step 3: Combine Coconut Ingredients
Gradually pour in the full-fat canned coconut milk while whisking continuously to create a smooth batter. Next, add the shredded sweetened coconut, glutinous rice flour, and vanilla extract. Stir until all the ingredients are well incorporated, ensuring there are no lumps. The consistency should be thick yet pourable, embodying that rich coconut flavor characteristic of a Sticky Coconut Cake.
Step 4: Pour the Batter and Bake
Carefully pour the batter into your prepared baking pan, spreading it into an even layer with a spatula. Place the pan in your preheated oven and bake for 45 minutes. Watch for the top to develop a light golden color and a slightly firm texture, indicating that your Sticky Coconut Cake is almost ready.
Step 5: Brush with Egg Yolk and Broil
Once baked, remove the cake from the oven and let it cool slightly. In a small bowl, beat the reserved egg yolk, then gently brush it over the top of the cake. This step adds a beautiful shine and an extra layer of flavor. Return the cake to the oven under the broiler for an additional 5-10 minutes, or until the top is golden brown—keep a close eye to prevent burning.
Step 6: Cool and Refrigerate
After broiling, allow the cake to cool completely on a wire rack. This cooling process helps set the texture. Once cooled, cover it with plastic wrap or foil and refrigerate for at least 8 hours, or preferably overnight. This chilling time is key to achieving the perfect chewy consistency that makes the Sticky Coconut Cake so delightful when served.
Step 7: Slice and Serve
After refrigeration, take the cake out and let it sit at room temperature for a few minutes. Use a sharp knife to cut it into squares or triangles. The cake will have a silky texture with a slight stickiness, ready to wow your family and friends with its delicious flavors. Serve chilled or at room temperature, perhaps alongside a cup of coffee or tea, for a delightful treat!

Sticky Coconut Cake Recipe FAQs
What should I look for when selecting eggs for the Sticky Coconut Cake?
Choosing fresh eggs is crucial for your Sticky Coconut Cake. Look for eggs that are clean and have no cracks. Additionally, check the sell-by date to ensure they are fresh. If you’re looking for a vegan version, I recommend using aquafaba, which is the liquid from canned chickpeas and can be whipped just like egg whites.
How should I store the Sticky Coconut Cake?
To keep your Sticky Coconut Cake deliciously fresh, store it in an airtight container in the refrigerator for up to 2 weeks. This method helps retain its delightful coconut flavor and chewy texture, so you can enjoy every bite over multiple days!
Can I freeze the Sticky Coconut Cake, and if so, how?
Absolutely! Freezing is a great way to extend the life of your Sticky Coconut Cake. I recommend wrapping individual slices tightly in plastic wrap and then placing them inside a freezer-safe bag. This way, they will remain luscious for up to 3 months. When you’re ready to indulge, simply transfer a slice to the fridge the night before to thaw for best results.
What if my Sticky Coconut Cake doesn’t set properly?
If your cake doesn’t set as expected, check that you used glutinous rice flour instead of all-purpose flour, as the former is essential for the cake’s texture. Additionally, ensuring you’ve mixed all ingredients thoroughly can prevent lumps. If the cake is too thick, it may need a bit more coconut milk next time, or perhaps a longer baking time. Always trust your instincts and bake until you achieve that lovely golden crust!
Is this Sticky Coconut Cake suitable for those with allergies?
This recipe contains coconut and eggs, so if you or your loved ones have allergies, take extra precautions! You can substitute the eggs with aquafaba for a vegan version. For those allergic to coconut, this cake might not be suitable since coconut is the star ingredient, but you could experiment with another flour-based cake for a different treat.
How do I know if my coconut milk is good to use?
When using full-fat canned coconut milk, make sure to shake it well before use to recombine any separated layers. If the coconut milk appears grainy or has an off-putting smell, it’s better to discard that can and choose a fresh one. Good quality coconut milk will provide a rich and smooth flavor, elevating your Sticky Coconut Cake experience!
