Sticky Coconut Cake Ingredients
For the Batter
• Eggs (2, separated) – Provides structure and richness; substitute aquafaba for a vegan option.
• Granulated Sugar (1¼ cup) – Sweetens the cake; you can use coconut sugar for a deeper flavor.
• Canned Coconut Milk (2¼ cup) – Adds moisture and a strong coconut flavor; shake well before use to prevent separation.
• Shredded Sweetened Coconut (3 cups) – Enhances the cake’s coconut texture; feel free to use unsweetened if preferred.
• Glutinous Rice Flour (1½ cup) – This key ingredient gives that chewy texture; do not substitute with all-purpose flour.
• Vanilla Extract (1 teaspoon) – Adds aromatic flavor to the cake.
For the Topping
• Egg Yolk (1, beaten) – Brushing on top gives the cake a lovely golden brown color; brush gently to avoid tearing.
Step‑by‑Step Instructions for Sticky Coconut Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that the temperature is just right for baking the Sticky Coconut Cake. While the oven warms up, gather your ingredients and equipment, including an 8×8-inch baking pan, mixing bowls, and a whisk for easy preparation.
Step 2: Whisk Egg Whites and Sugar
In a mixing bowl, combine the separated egg whites and granulated sugar. Use a whisk to blend them together until fully combined and slightly frothy, which should take about 2-3 minutes. This step helps to incorporate air, contributing to the cake’s delightful chewy texture.
Step 3: Mix in Coconut Milk and Flavorings
Gradually pour in the canned coconut milk while continuing to whisk. Once incorporated, add in the vanilla extract and mix until smooth. The mixture should have a creamy consistency, rich with coconut flavor, ready to embrace the dry ingredients for your Sticky Coconut Cake.
Step 4: Combine with Dry Ingredients
Next, add the shredded sweetened coconut and glutinous rice flour to the wet mixture. Stir until everything is well combined and a thick batter forms. This step is key to achieving that lovely sticky texture, so be sure there are no dry patches of flour left in your bowl.
Step 5: Pour into the Baking Pan
Carefully transfer the batter into the prepared 8×8-inch baking pan, smoothing the top with a spatula to create an even layer. Bake in the preheated oven for about 45 minutes, or until the top is set and slightly golden. You’ll know it’s ready when a toothpick inserted comes out clean.
Step 6: Broil for a Golden Finish
Remove the pan from the oven and brush the surface of the cake with the beaten egg yolk. This will give it a beautiful golden brown color. Set your oven to broil and return the cake for an additional 5-10 minutes, keeping a close eye to avoid burning as it toasts.
Step 7: Cool and Set
Once broiled to perfection, take the cake out of the oven and let it cool to room temperature. This cooling period allows the flavors to meld beautifully. After about 30 minutes, cover the cake and refrigerate it overnight to achieve the ideal texture and set completely.
Step 8: Cut and Serve
When you’re ready to enjoy your Sticky Coconut Cake, remove it from the refrigerator and slice it into squares or triangles. It can be served chilled or at room temperature, perfect as a treat for gatherings or a comforting afternoon snack. Each bite is sure to delight coconut lovers!

Make Ahead Options
These Sticky Coconut Cakes are fantastic for meal prep, saving you time when you’re busy. You can prepare the batter and pour it into the pan up to 24 hours in advance; just cover it tightly and refrigerate to keep it fresh. Alternatively, bake the cake and let it cool, then refrigerate it overnight to allow the flavors to develop beautifully. When you’re ready to enjoy, simply brush the top with the beaten egg yolk and broil for 5-10 minutes to achieve that gorgeous golden finish. This way, you’ll have a delicious, chewy dessert ready to serve effortlessly during any gathering!

Sticky Coconut Cake Recipe FAQs
How should I choose ripe ingredients for this Sticky Coconut Cake?
Absolutely! When selecting eggs, look for ones that are fresh, with no cracks; the fresher, the better for this recipe. For the canned coconut milk, ensure it’s labeled without additives—just coconut and water for the best flavor. If you’re using fresh shredded coconut, it should smell sweet and have a soft texture. Avoid any pieces with discoloration.
How should I store my Sticky Coconut Cake, and how long will it last?
The more the merrier! You can store your Sticky Coconut Cake in an airtight container in the refrigerator, where it will stay fresh for up to 2 weeks. This helps maintain its delightful chewy texture while ensuring you have a sweet nibble ready any time you crave a coconut treat.
Can I freeze Sticky Coconut Cake, and how do I do it?
Of course! To freeze, first let your cake cool completely. Cut it into individual squares and arrange them in a single layer on a baking sheet. Place the sheet in the freezer for about 1-2 hours until the pieces are firm, then transfer them to a freezer-safe container. It can last for up to 3 months! When you’re ready to enjoy, simply thaw overnight in the refrigerator or microwave for 15-20 seconds.
What if my Sticky Coconut Cake turns out too dry or too moist?
Very! If the cake is too dry, you may have overbaked it. Make sure to check for doneness with a toothpick at the 45-minute mark—remove it as soon as it comes out clean, not too dry. Conversely, if it’s too moist, ensure you’re measuring the ingredients accurately, especially the glutinous rice flour. Too much liquid can lead to a different texture. Adjusting the baking time might also help!
Are there any dietary considerations or allergy concerns for this recipe?
Absolutely! This Sticky Coconut Cake is naturally gluten-free due to the use of glutinous rice flour, making it a great option for those with gluten sensitivities. However, if you’re baking for someone with nut allergies, double-check your sweetened coconut, as some brands may contain traces. If you’re vegan, remember you can substitute the egg whites with aquafaba for a delicious plant-based version!
