Coconut Cupcakes with Buttercream Frosting are tender, full of coconut flavor and have the most amazing lime flavored buttercream ever! Needless to say, these cupcakes are at the top of my list of favorites!
I loved these cupcakes so much, that after we switched over to a Kety lifestyle, I remade them into a keto version! If you are interested in Keto recipes, then be sure to try my recipe for Keto Coconut Cupcakes!
Cooking Light Recipe - Family Favorite
I originally found the original Coconut Cupcake recipe in a Cooking Light magazine. One ingredient out of the norm in this recipe is potato starch. This is not something I normally keep on hand so I looked for a substitute and found you can easily substitute cornstarch. And, your cupcakes will still turn out light and delicious.
I am completely and totally enamored with coconut and lime. I love flavors separately, but I really love them combined. That makes these cupcakes the number one favorite (non-chocolate recipe) on my list!
FAQ about this Coconut Cupcake Recipe
Can I use coconut extract in place of the vanilla extract?
You can use any flavor that may compliment your cupcake and the lime buttercream frosting.
What is potato starch and why is it used in this recipe?
Potato starch is very similar to cornstarch. It can be used as a thickener and adds moistness to baked goods. Cornstarch can be used in place of potato starch.
Can I substitute unsweetened coconut in place of sweetened coconut?
Sweetened coconut is just that, coconut with added sweetener. It is moister than unsweetened coconut. Having said that, you can substitute. You can expect the cupcake to have a little less sweetness to it but it shouldn't affect the final product.
Tips for making Coconut Cupcakes with Lime Buttercream Frosting
- Coconut can have long strands. Since you are using only 2 tablespoons of coconut, I recommend chopping it before measuring it. This way you don't have long "string like" pieces of coconut in your cupcake.
- For an actual coconut flavor, substitute coconut extract in place of vanilla in the cupcake portion of the recipe.
- When making the frosting, be sure your butter is at room temperature. If it's too hard, it will not cream well with the powdered sugar.
- If your frosting doesn't have enough lime flavor, you can always add another tablespoon of lime juice. You may need to add a little more powdered sugar if you do so to make sure the frosting is of spreading consistency.
Bonus tip: Do you want MORE lime flavor? Zest a little extra lime rind and sprinkle it on top of the coconut cupcakes. It not only adds flavor but makes it look prettier in presentation also.
