Blue Ribbon Recipe

These semi-homemade cupcakes are tender and moist with a tropical feeling that tastes like summer. The coconut cupcake flavor is subtle and pairs well with the pureed mango. Inside is a rich filling that's sweet and tart from key lime juice. The creamy frosting has mango puree and key lime juice to add to the tropical feel and bring all the elements together. They'd be perfect for a pool party or summer barbecue. They take a little time but are worth the effort.

How To Make mango key lime cupcakes

Test Kitchen Tips
We used two (2) 10oz bags of frozen mango, defrosted, for this recipe. We recommend storing these in the fridge. There will be more frosting than is needed. Feel free to cut the recipe in half. We did and used 1/4 cup of mango puree. If you can't find coconut cake mix, use a white cake mix and add 1 1/2 teaspoons of coconut extract.
  • Filling ingredients in a saucepan.
    1
    For the custard filling, in a medium saucepan combine all ingredients. Whisk over medium/high heat until the mixture thickens.
  • Transfer filling to a bowl and cover in plastic wrap.
    2
    Transfer to a small bowl. Cover with plastic wrap, with the wrap touching the custard. Chill for 3 - 4 hours.
  • Puree the mango.
    3
    For the cake, puree the mangos in a food processor or blender. Preheat oven to 350 degrees F.
  • Combine cake mix, sugar, and flour.
    4
    Mix the cake mix, sugar, and flour in a large bowl.
  • Add water, sour cream, oil, mango, and eggs.
    5
    Add in the wet ingredients - water, sour cream, oil, mango, and eggs. Beat on low until mixed. Then beat on medium/high for 2 minutes.
  • Line cupcake tin with paper cups and fill 2/3 way full.
    6
    Line cupcake pan with paper cups and fill 2/3 way full with batter. Turn oven down to 325 degrees and bake for about 25 - 35 minutes or until a toothpick comes out clean.
  • Cool the cupcakes.
    7
    Cool cupcakes for 10 minutes and then transfer them to a cooling rack. Cool completely.
  • Combine butter, shortening, vanilla, lime juice, and mango for the frosting.
    8
    For the frosting, combine butter, shortening, vanilla, lime juice, and mango in a large mixing bowl. Beat on high for 5 minutes.
  • Slowly add powdered sugar.
    9
    Turn the mixer to low. Add the powdered sugar, little by little, until the mixture becomes thick and creamy and there are no lumps. Add more or less powdered sugar as needed for the desired consistency.
  • Hollow out the center of the cupcakes.
    10
    Once the cupcakes are cool, hollow out the center of the cupcakes.
  • Pipe filling into the cupcakes.
    11
    Load the filling into a piping bag or resealable plastic bag and fill the center of each cupcake with the chilled filling.
  • Frost the cupcakes and decorate.
    12
    Place frosting in a piping bag with whatever tip you like and frost away. Garnish with key lime zest, key lime slice, or sprinkles.
