How to Make Mango Key Lime Cupcakes
-
Preheat the oven to 350°F (175°C) and line a 12-cup muffin pan with paper liners. This step ensures your cupcakes bake evenly and don’t stick to the pan.
-
Combine in a large bowl the coconut cake mix, all-purpose flour, sugar, water, sour cream, vegetable oil, eggs, and pureed mango. Mix until the batter is smooth and well-combined—this should take just a couple of minutes.
-
Fill each cupcake liner two-thirds full with the batter, making sure they’re all evenly distributed for perfect rising. Bake for 18-22 minutes, or until a toothpick inserted comes out clean. Let them cool completely.
-
Whisk together in a saucepan the sweetened condensed milk, whole or 2% milk, key lime juice, lime zest, and vanilla pudding mix. Cook over medium heat until thickened, stirring often. Once thick, remove from heat and allow to cool completely before filling the cupcakes.
-
Beat the butter and vegetable shortening in a mixing bowl until creamy. Add in the vanilla extract, fresh key lime juice, and pureed mango. Gradually mix in the powdered sugar until the frosting is smooth and fluffy.
-
Pipe the frosting generously onto each cupcake. Be artistic and have fun with it! Garnish with lime zest, a slice of key lime, and a sprinkle of colorful sprinkles to make them pop.
-
Chill the cupcakes for at least 20 minutes before serving. This enhances their flavors and texture, making each bite even more delicious!
Optional: Garnish with additional sprinkles for an extra pop of color.

For the custard filling, make it up to 3 days ahead, refrigerating it in a sealed container to keep it fresh and creamy. The frosting can also be made in advance and stored separately, so all you need to do is pipe it on when you’re ready to serve! Just remember to chill the cupcakes for at least 20 minutes before serving to ensure that burst of tropical flavor shines through. With these prep tips, you’ll have a delightful tropical treat ready with minimal effort!
How to Store and Freeze Mango Key Lime Cupcakes
Room Temperature: Keep the cupcakes in an airtight container for up to 2 days at room temperature to maintain their freshness and flavor.
Fridge: If you have leftovers, store the cupcakes in the refrigerator for up to 5 days. Make sure they are tightly wrapped or sealed to prevent them from drying out.
Freezer: For longer storage, freeze the Mango Key Lime Cupcakes without frosting for up to 3 months. Wrap each cupcake individually in plastic wrap, then place them in a freezer-safe bag.
Reheating: Thaw the frozen cupcakes in the fridge overnight, then enjoy them chilled or bring them back to room temperature before frosting and serving.
Chef's Helpful Tips
- When making Mango Key Lime Cupcakes, ensure your ingredients are at room temperature for a smoother batter and better incorporation.
- Avoid overmixing the batter to prevent dense cupcakes; mix just until the ingredients are combined for a lighter consistency.
- For the custard filling, allow the mixture to cool completely before filling the cupcakes to maintain structure and prevent sogginess.
- Monitor the cupcakes closely while baking, as oven temperatures can vary; start checking for doneness at the 18-minute mark to avoid overbaking.
Mango Key Lime Cupcakes Recipe FAQs
How do I choose ripe mangoes for this recipe?
Absolutely! When selecting mangoes, look for ones that give slightly to pressure, indicating they are ripe. Their skin should have a vibrant color with little to no dark spots. A ripe mango will also have a sweet, fruity aroma at the stem end. If they’re not quite ripe, you can let them sit at room temperature for a day or two to reach the perfect softness.
How should I store leftover Mango Key Lime Cupcakes?
To maintain the delightful taste and moistness of your cupcakes, store them in an airtight container. At room temperature, they will stay fresh for up to 2 days. If you want to keep them longer, refrigerate them for up to 5 days—just ensure they’re well-wrapped to prevent drying out.
Can I freeze the Mango Key Lime Cupcakes?
Very! You can freeze the un-frosted cupcakes for up to 3 months. Start by wrapping each cupcake individually in plastic wrap to prevent freezer burn, then place them in a freezer-safe bag. When you’re ready to enjoy them, thaw the cupcakes in the fridge overnight and allow them to come to room temperature before frosting.
What if my cupcakes don’t rise properly?
If your cupcakes don’t rise as expected, it might be due to expired baking powder or not mixing the batter enough. Make sure your ingredients, especially the baking powder, are fresh, and mix until just combined to avoid overloading the batter with air. If they still don’t rise, check your oven temperature with a thermometer, as it might be running too low or high.
Are these cupcakes suitable for those with allergies?
For those with dietary restrictions, you can make adjustments! Substitute all-purpose flour with a gluten-free blend, and for a dairy-free option, use almond or coconut milk in place of regular milk and sour cream. Always tailor your selection based on the specific allergies of your guests, as some may still react to coconut or other alternatives.
How can I make these cupcakes vegan?
To veganize the Mango Key Lime Cupcakes, replace the eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water equals one egg). Use a plant-based butter substitute and vegan sour cream or a blend of silken tofu and lemon juice as replacements. This way, you can still enjoy the vibrant flavors while accommodating vegan diets!
