Ingredients
- For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup (2 sticks) unsalted butter, melted
- 1 cup coconut milk (full-fat, canned)
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 teaspoon coconut extract
- 1 cup shredded sweetened coconut
- For the Frosting:
- 1 cup (2 sticks) unsalted butter, softened
- 6 cups powdered sugar
- 1/2 cup coconut milk (full-fat, canned)
- 1 teaspoon vanilla extract
- 1/2 teaspoon coconut extract
- 1 cup shredded sweetened coconut, for topping

Instructions
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. You can also line the pan with parchment paper, leaving an overhang for easy removal.
- Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking soda, baking powder, and salt.
- Add Wet Ingredients: Add the melted butter, coconut milk, eggs, vanilla extract, and coconut extract to the dry ingredients. Mix until just combined. Be careful not to overmix.
- Fold in Coconut: Gently fold in the shredded coconut.
- Bake: Pour the batter into the prepared baking pan and spread evenly. Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
- Cool: Let the cake cool in the pan for 10-15 minutes before inverting it onto a wire rack to cool completely.
- Make the Frosting: While the cake is cooling, prepare the frosting. In a large bowl, beat the softened butter with an electric mixer until light and fluffy.
- Add Powdered Sugar and Coconut Milk: Gradually add the powdered sugar, alternating with the coconut milk, beating until smooth and creamy.
- Flavor the Frosting: Stir in the vanilla extract and coconut extract.
- Frost the Cake: Once the cake is completely cool, frost it with the coconut frosting.
- Garnish: Sprinkle the remaining shredded coconut over the top of the frosted cake.
- Slice and Serve: Slice the cake into squares and serve. Enjoy!
Tips for Success
Follow these tips to ensure your coconut sheet cake turns out perfectly every time:
- Use Full-Fat Coconut Milk: Full-fat coconut milk provides the richest flavor and the most moisture for the cake and frosting.
- Don’t Overmix the Batter: Overmixing can develop the gluten in the flour, resulting in a tough cake. Mix until just combined.
- Use Room Temperature Eggs: Room temperature eggs emulsify better, creating a smoother batter.
- Cool the Cake Completely: Frosting a warm cake will cause the frosting to melt. Make sure the cake is completely cool before frosting.
- Adjust Sweetness to Taste: If you prefer a less sweet frosting, you can reduce the amount of powdered sugar slightly.
- Toast the Coconut: For an even more intense coconut flavor, lightly toast the shredded coconut before adding it to the batter and using it as a topping. To toast, spread the coconut on a baking sheet and bake at 350°F (175°C) for 5-7 minutes, or until lightly golden, watching carefully to prevent burning.
- Add a Glaze (Optional): For an extra layer of coconut flavor, consider adding a coconut glaze after the cake has cooled slightly, before frosting. A simple glaze can be made with powdered sugar and coconut milk.
Storage Instructions
Store leftover coconut sheet cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. The cake will stay moistest when stored at room temperature. You can also freeze the cake for up to 2 months. Wrap the cake tightly in plastic wrap and then in foil before freezing. Thaw the cake overnight in the refrigerator before serving.

FAQ
Here are some frequently asked questions about this coconut sheet cake recipe:
- Can I use unsweetened coconut? Yes, you can use unsweetened coconut, but the cake and frosting will be less sweet. You may want to add a little extra sugar to the batter or frosting to compensate.
- Can I use a different type of milk? While coconut milk is essential for the coconut flavor, you can substitute regular milk or buttermilk for the coconut milk in the cake batter if needed. However, the coconut flavor will be less pronounced.
- Can I make this cake gluten-free? Yes, you can substitute a gluten-free all-purpose flour blend for the regular flour. Be sure to use a blend that contains xanthan gum for best results.
- Can I add nuts? Yes, chopped nuts like macadamia nuts or pecans would be a delicious addition to this cake. Add about 1/2 cup of chopped nuts to the batter along with the coconut.
- My cake is dry, what did I do wrong? Overbaking is the most common cause of dry cake. Be sure to check the cake for doneness at the minimum baking time and remove it from the oven as soon as a wooden skewer inserted into the center comes out clean.
