Step‑by‑Step Instructions for Coconut Sheet Cake
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While it warms up, prepare your baking pan—lightly grease it to ensure your Coconut Sheet Cake comes out easily. A 12x17-inch sheet pan works perfectly for this recipe, giving you that ideal shape for serving.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This harmonious blend ensures that your cake will rise beautifully and have a fluffy texture. Set this aside while you work on the wet ingredients, allowing the baking powder to activate.
Step 3: Cream Butter and Sugar
In a separate bowl, beat the softened unsalted butter and granulated sugar together until you achieve a light and fluffy texture, which should take about 3 to 4 minutes. This step is key for incorporating air into your Coconut Sheet Cake batter, leading to a tender crumb.
Step 4: Incorporate Eggs and Vanilla
Add the eggs one at a time to the creamed mixture, ensuring thorough mixing after each addition. Stir in the vanilla extract and watch as these ingredients blend seamlessly, creating a delightful aroma that fills your kitchen with warmth.
Step 5: Combine Wet and Dry Ingredients
Gradually add the flour mixture to your wet mixture, alternating with the coconut milk. Begin and end with the flour, mixing until just combined. The batter should be smooth and slightly thick—savor the tropical scent of coconut as you fold the ingredients together.
Step 6: Pour and Smooth Batter
Pour the batter into your prepared baking pan, using a spatula to gently smooth the top. This even distribution will help your Coconut Sheet Cake bake uniformly. Look for a nice glossy finish on the surface of the batter before it heads into the oven.
Step 7: Bake the Cake
Place your pan in the preheated oven and bake for 25 to 30 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean when the cake is ready. Enjoy the delightful aroma wafting through your home as it bakes.
Step 8: Cool the Cake
Once baked, remove the pan from the oven and allow the cake to cool completely on a wire rack for about 1 hour. This cooling step is crucial, so the cake can set properly before you proceed to frost it with the heavenly whipped cream topping.
Step 9: Prepare the Whipped Topping
In a chilled mixing bowl, beat the cold heavy cream and cold coconut milk until soft peaks form. This should take a few minutes—keep an eye on the texture, aiming for a fluffy base that will hold your light and airy whipped topping.
Step 10: Sweeten the Cream
Gradually add confectioners' sugar while continuing to beat the mixture until firm peaks develop. The whipped topping should be thick enough to spread beautifully over your cooled Coconut Sheet Cake, providing a creamy and sweet contrast to the moist cake below.
Step 11: Assemble the Cake
Spread the whipped topping generously over the cooled cake, ensuring an even layer that covers every inch. For an inviting finish, sprinkle sweetened shredded coconut on top. This adds delightful texture and a burst of coconut flavor, making your Coconut Sheet Cake a showstopper!
Step 12: Serve and Enjoy
Slice your Coconut Sheet Cake into generous pieces and serve it at room temperature. Whether it's for a special occasion or a simple treat, the joy it brings to your gatherings will create lasting memories. Enjoy every bite of this tropical delight!

Make Ahead Options
These Coconut Sheet Cake preparations are perfect for busy home cooks wanting to save time! You can make the cake up to 24 hours in advance; simply bake it and allow it to cool completely before refrigerating. To maintain its moisture, wrap the cake tightly in plastic wrap. You can also whip the topping (heavy cream and coconut milk) up to 3 days ahead and store it in an airtight container in the fridge. When you’re ready to serve, frost the chilled cake with the whipped topping and add the toasted shredded coconut—this ensures every slice tastes just as delightful as the day it was baked! Enjoy the ease of meal prep while bringing tropical joy to your gatherings!

Tips for the Best Coconut Sheet Cake
- Use Fresh Ingredients: Ensure your baking powder and baking soda are fresh for the best rise in your Coconut Sheet Cake. Old ingredients can lead to a dense texture.
- Room Temperature Eggs: Always use room temperature eggs to help create a smooth batter and improve the cake's overall texture.
- Don't Overmix: When combining the wet and dry ingredients, mix until just combined. Overmixing can make your cake tough instead of tender.
- Chill the Whipping Cream: For the best whipped topping, chill your bowl and heavy cream beforehand. Cold cream whips better and holds its shape longer.
- Toast the Coconut: For extra flavor, consider toasting the sweetened shredded coconut before using it as a topping. This adds a lovely depth to your Coconut Sheet Cake.

Coconut Sheet Cake Recipe FAQs
Which coconut milk should I use for the Coconut Sheet Cake?
I recommend using full-fat canned coconut milk for this recipe. It not only contributes to the cake's delightful moisture but also enhances the coconut flavor. Avoid using light coconut milk, as it may result in a denser cake with less richness.
How should I store the Coconut Sheet Cake?
To keep your Coconut Sheet Cake fresh, cover it with plastic wrap or place it in an airtight container. It can be stored at room temperature for up to 3 days or in the refrigerator for up to a week. If storing in the fridge, make sure it’s well-sealed to prevent it from absorbing any other odors.
Can I freeze the Coconut Sheet Cake?
Absolutely! To freeze, allow the cake to cool completely, then wrap it tightly in plastic wrap and then in aluminum foil. You can safely freeze it for up to 3 months. When you're ready to enjoy it, simply transfer it to the refrigerator to thaw overnight before serving.
What should I do if my cake sinks in the middle?
If your Coconut Sheet Cake sinks in the middle, it might be due to underbaking or too much mixing. To avoid this, always check for doneness by inserting a toothpick in the center; it should come out clean. Also, be cautious not to overmix the batter, as this can add too much air and lead to sinking.
Is this recipe suitable for those with allergies?
This Coconut Sheet Cake does contain common allergens like eggs and dairy. If you or someone you're serving has allergies, consider using egg substitutes (like flax or applesauce) and plant-based butter and coconut cream to make this recipe suitable for a vegan diet. Always double-check product labels for allergen information before using.
Can I use unsweetened shredded coconut instead of sweetened?
You can definitely use unsweetened shredded coconut; however, you might want to adjust the sugar in the cake slightly to balance the flavors. Unsweetened coconut will still provide texture and a lovely coconut flavor, but the sweetness will be more subtle. If you’re toasting the coconut, watch it carefully to avoid burning!
