Ingredients

For the Cupcakes:

Cooking spray
4 1/2 ounces flour (approximately 1 cup)
3 tablespoons potato starch (or corn starch)
1 teaspoon baking powder
1/2 teaspoon salt
3/4 cup sugar
2 tablespoons butter, softened
1 large egg
1 large egg white
2/3 cup skim milk
2 tablespoons sweetened flaked coconut
1/2 teaspoon vanilla extract

For the Frosting:

3 tablespoons butter, softened
1 teaspoon half-and-half (you can also use fat-free half-and-half)
1/2 teaspoon grated lime rind
1 tablespoon fresh lime juice
4 3/4 ounces powdered sugar, sifted (approximately 1 1/3 cups)

Equipment Needed

12-cup muffin tin
Muffin cup liners
Small bowl
Large bowl
Electric mixer
Measuring cups and spoons
Whisk
Rubber spatula
Sifter (for powdered sugar)

Instructions

Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Prepare a 12-cup muffin tin by placing two muffin cup liners in each cup for added support and ease of removal. Generously coat the liners with cooking spray to prevent the cupcakes from sticking.
Prepare the dry ingredients. In a small bowl, carefully measure and combine 4 1/2 ounces (approximately 1 cup) of flour, 3 tablespoons of potato starch (or corn starch as a substitute), 1 teaspoon of baking powder, and 1/2 teaspoon of salt. Whisk these ingredients together thoroughly to ensure they are evenly distributed, which will help create a uniform texture in your cupcakes.
Cream together the butter and sugar. In a large bowl, combine 3/4 cup of sugar and 2 tablespoons of softened butter. Using an electric mixer set to medium speed, beat the sugar and butter until the mixture is well blended. Continue mixing until the consistency resembles damp sand, ensuring there are no large clumps of butter remaining. This step is crucial for creating a light and airy cupcake.
Incorporate the eggs. Add 1 large egg to the sugar and butter mixture and beat well until fully incorporated. Then, add 1 large egg white and beat again until the mixture is smooth and homogenous. Adding the egg and egg white one at a time and beating well after each addition ensures that the ingredients are properly emulsified, contributing to the cupcake’s structure and moisture.
Combine wet and dry ingredients. Gradually add the flour mixture and skim milk to the batter alternately, beginning and ending with the flour mixture. This method helps prevent overmixing, which can result in tough cupcakes. Fold in 2 tablespoons of sweetened flaked coconut and 1/2 teaspoon of vanilla extract. Gently fold until just combined, being careful not to overmix. Overmixing develops the gluten in the flour, leading to a denser, less tender cupcake.
Fill and bake the cupcakes. Using a spoon or an ice cream scoop, evenly distribute the cupcake batter into the prepared muffin cups. Fill each cup approximately two-thirds full to allow room for the cupcakes to rise during baking. Bake at 350 degrees Fahrenheit (175 degrees Celsius) for 18 minutes, or until the surface springs back up when lightly touched in the center. A toothpick inserted into the center should come out clean or with a few moist crumbs.
Cool the cupcakes. Once baked, remove the muffin tin from the oven and let the cupcakes cool in the tin for a few minutes before transferring them to a wire rack to cool completely. Cooling the cupcakes completely before frosting prevents the frosting from melting and ensures a clean and professional finish.
Prepare the frosting. While the cupcakes are cooling, prepare the lime buttercream frosting. In a medium bowl, combine 3 tablespoons of softened butter, 1 teaspoon of half-and-half (or fat-free half-and-half), 1/2 teaspoon of grated lime rind, and 1 tablespoon of fresh lime juice. Beat with an electric mixer at medium speed until the mixture is smooth and well combined.
Add the powdered sugar. Gradually add 4 3/4 ounces (approximately 1 1/3 cups) of sifted powdered sugar to the butter mixture. Beat until the frosting is smooth, light, and fluffy. Sifting the powdered sugar before adding it to the frosting ensures that there are no lumps, resulting in a silky smooth texture.
Frost the cupcakes. Once the cupcakes are completely cool, spread approximately 2 1/2 teaspoons of lime buttercream frosting onto each cupcake. You can use a knife, spatula, or piping bag to apply the frosting, depending on your desired presentation.

Expert Tips & Tricks

Room Temperature Ingredients: Using room-temperature butter, eggs, and milk ensures that the ingredients blend together smoothly and evenly, creating a more consistent batter and a better final product.
Don’t Overmix: Overmixing the batter develops the gluten in the flour, which can result in tough cupcakes. Mix the wet and dry ingredients until just combined.
Even Baking: To ensure even baking, rotate the muffin tin halfway through the baking time. This helps to distribute the heat more evenly and prevents the cupcakes from browning unevenly.
Lime Zest Power: For a more intense lime flavor, gently rub the lime zest with the sugar before adding the butter. This releases the oils in the zest and intensifies the flavor.
Make-Ahead Frosting: The lime buttercream frosting can be made ahead of time and stored in the refrigerator for up to 3 days. Allow it to come to room temperature and rewhip before using.

Serving & Storage Suggestions

These Coconut Cupcakes with Lime Buttercream Frosting are best served at room temperature. To enhance the presentation, consider garnishing the cupcakes with a sprinkle of extra flaked coconut or a thin slice of lime.

Storage:

Room Temperature: Frosted cupcakes can be stored at room temperature in an airtight container for up to 2 days.
Refrigerator: For longer storage, store the cupcakes in an airtight container in the refrigerator for up to 5 days. Allow them to come to room temperature before serving.
Freezer: Unfrosted cupcakes can be frozen for up to 2 months. Wrap them individually in plastic wrap and then place them in a freezer-safe bag or container. Thaw completely before frosting. Frosted cupcakes are not recommended for freezing, as the frosting may become watery upon thawing.

Dairy-Free: Use a dairy-free butter substitute and non-dairy milk such as almond, soy, or oat milk in both the cupcakes and the frosting.
Coconut Milk: Substitute the skim milk with full-fat coconut milk for a richer coconut flavor.
Lime Infusion: Infuse the skim milk with lime zest by heating it gently with the zest and allowing it to steep for 30 minutes before using in the recipe.
Tropical Twist: Add a tablespoon of rum extract to the batter for a more tropical flavor.

FAQs (Frequently Asked Questions)

Q: Can I use all-purpose flour instead of potato starch or corn starch?

A: While you can, the potato or corn starch helps to create a lighter, more tender cupcake. If substituting, use the same amount (3 tablespoons) of all-purpose flour.

Q: My frosting is too thin. What can I do?

A: Gradually add more sifted powdered sugar, one tablespoon at a time, until the frosting reaches your desired consistency.

Q: Can I use bottled lime juice instead of fresh?

A: Fresh lime juice provides a brighter, more vibrant flavor. However, if necessary, you can use bottled lime juice. Adjust the amount to taste.

Q: How do I prevent the cupcakes from sticking to the liners?

A: Ensure the liners are thoroughly coated with cooking spray. You can also use parchment paper liners for easier removal.

Q: Can I add more coconut to the cupcakes?

A: Yes, you can increase the amount of sweetened flaked coconut to 1/4 cup for a more pronounced coconut flavor.
