Wow. I just took a look at my site meter and there are a LOT of people out there visiting in the hopes of catching my Coconut Key Lime Cupcake recipe! I found the idea for this recipe over at Cupcake Bakeshop by Chockylit. She has some amazing cupcake recipes over there.

A long time back, she'd posted some Coconut Lime cupcakes and, in her comments, had made mention of possibly later using coconut milk instead of the lime juice she'd originally tried.

Well, I trundled off to my kitchen and did just that. Plus, a little more. The resulting cupcake was so flippin' yummy I had to chain them up, lest I turn into a little piglet, grunting as I stuffed my face full of islandy goodness.

Then, the next year, I added a little more to the mix... Alcohol. Because, you know, everyone loves an alcoholic cupcake during the summertime. I think it was for a July 4th party and I made some as mini-cupcakes, unfilled. Oh My.

So. Hopefully some of those visitors will come back because, well... it's summer, and now I have cupcake on the brain, and here's the recipe:

First, you want to do your filling. It needs to set up in the fridge and get nice and chilly.

Key Lime Pie Filling
Will fill 48 regular cupcakes with a little more than a teaspoon each / 325° oven

4 large or extra large egg yolks
1 14oz can sweetened condensed milk
½ cup fresh key lime juice (approx. 6 – 8 limes)

2 teaspoons grated lime zest

1. Preheat oven to 325°.
2. Beat the egg yolks until they are thick and turn light yellow.
3. Turn mixer off and add the sweetened condensed milk.
4. Turn speed to low and then add half of the lime juice.
5. Once the juice is incorporated, add the remainder of the juice and mix until blended.
6. Add the grated lime zest and stir in by hand.
7. Pour the mixture into a regular glass pie dish (or any glass dish which will fit inside a larger baking dish/pan).
8. Set dish with mixture into a larger pan. Fill larger pan half full of hot water.
9. Place in oven and bake until custard is just set in the middle, about 13 minutes.
10. Remove from the oven and carefully remove the pie dish.

11. Cover with plastic wrap and refrigerate at least 3-4 hours or overnight.

Now, let's move on to the cupcakes themselves, the stars of the show, the package to contain the yummy goodness of key lime filling...

Coconut Cupcakes
24 regular cupcakes / 350° oven

2 sticks unsalted butter, room temperature
2 cups sugar
4 large eggs, room temperature
2-2/3 cups all-purpose flour
1-teaspoon baking powder
1-teaspoon baking soda
1/4-teaspoon salt
1 cup canned coconut milk (shake can well before opening)
2 teaspoons vanilla

1 cup shredded sweetened coconut

1. Beat butter on high until soft, about 30 seconds.
2. Add sugar. Beat on medium-high until light and fluffy, about 3 minutes.
3. Add eggs one at a time, beating for 30 seconds between each.
4. Whisk together flour, baking powder, and baking soda in a bowl.
5. Measure out milk and vanilla together.
6. Add about a fourth of the flour to the butter/sugar mixture and beat to combine.
7. Add about one third of the milk/vanilla mixture and beat until combined.
8. Repeat above, alternating the flour and milk, ending with the flour mixture.
9. Scoop into cupcake papers, about three-quarters full. (one ice cream scoop does really well)
10. Bake for 20-22 minutes until a cake tester comes out clean.**

** My oven runs hot, but even so… mine only took 13 minutes @ 325 to bake to a perfect pale golden brown. You might want to test one before baking all of them.

Next, while all of your cupcakes are cooling and your filling is chilling, it's time to hit the buttercream!

Coconut-Lime Buttercream Frosting
Enough to lightly frost 24 regular cupcakes

1 stick butter, room temperature
4-5 cups powdered sugar, sifted
1/4 cup canned coconut milk (shake can well before opening)

1-1/2 teaspoon lime zest

1. Beat butter on high for about 30 seconds until soft.
2. Add 1 cup of sugar until incorporated.
3. Add half the milk and the remainder of the sugar and beat until incorporated.

4. Add zest; continue to add milk until you reach the desired consistency.

Note -- Here's where some alcohol can come into play. Either add a few Tablespoons of coconut rum to the mix when you're putting in the milk OR replace some of the coconut milk with the coconut rum. I can't remember which one I did... but I did not use any more than 4 Tablespoons (that I recall - it's very possible I used more because I was tasting the rum as I added... Heh.)

Now, you have filling chilling, cupcakes cooling, and frosting hanging out in the bowl. Let's toast some coconut for the pretty topping. Be careful with this part... it's burns easily!

Toasted Coconut

1. Using either sweetened or fresh grated coconut, place on tin foil lined pan in 325° oven, for about 10 minutes, tossing often to get an even golden color.

Finally, it's time to put together some cupcakes! Though time-intensive, the results really are worth it.

To Assemble:

1. Using a small paring knife, go in at a 45 degree angle a scant 1/3" from the edge and cut out a circle from the top, leaving you with a cone. Flip the top over and cut off the cone. (Chockylit - linked at the top of this post - has some really good picture instructions to do this, I think)
2. Fill the cavity with teaspoon or so of filling. (I used a melon ball scoop, made it very simple)
3. Replace the top.
4. Frost with frosting.

5. Decorate the top with toasted coconut.

To Assemble with Coconut Rum in play:

1. Cut out your cone, as instructed above.
2. Using a spritzer bottle (seriously, I took a little old bottle of spray conditioner and cleaned the hell out of it and then filled it with rum), give the inside of the cupcake a good few sprays of rum.
3. Then, fill the cavity with filling, while singing the lime-in-the-coconut song.
4. Replace the top.
5. Spray MORE rum on it. Set aside. Add a few spritzes to your mouth. Sing louder.
6. Continue until all the cupcakes are done.
7. Spray MORE rum on the tops. I sprayed each top about 5 times. If your spray bottle really spritzes, you might want to do less or just do it until you're sick of hearing yourself sing. I never get tired of hearing myself sing... so I did quite a bit, I'm sure.
8. Now, frost them and decorate with toasted coconut.

Take these gems to a summer BBQ or a heat-wave pool party. You'll be the talk of the town. They're refreshing and islandy and ooooh gimme more! I have to go bake these now.

    They sound lovely! I went back to the trusty Vanilla Chai cupcakes this weekend. I was meant to be making them for people at work but I ate too many so there would not be enough for one each so I had to keep them all.

    Ha ha ha ha. MMMMMMM
