Key Lime Cupcakes

I had a request from one of Shannon's coworkers, to make key lime cupcakes. I remembered making them before on my old blog from a version of this recipe. They worked well then, so I thought I'd make them again.

The cupcake anatomy is basically a yellow cake flavored with lime juice and zest, filled with a sweet and creamy key lime filling and topped with coconut flavored whipped cream. You could really use any kind of topping for these. The recipe suggests meringue, but I think the whipped cream works even better and I'd guess that cream cheese would work well too.

It may be hard to find key limes or key lime juice in your grocery store. I don't think I've ever seen bottled key lime juice, but occasionally our stores will actually carry key limes. They are super tiny limes (around the size of a quarter). I sliced and squeezed quite a few of those little guys before getting a third of a cup, but they smelled really good! If you can find key lime juice, it'll save a lot of time.

These were apparently a big hit at the office. Yay! Shannon said that Adam really liked them, so mission accomplished.


Key Lime Cupcakes
from Cupcakes by the Cake Mix Doctor
makes 24 cupcakes

24 paper liners for cupcake pans (2 1/2-inch size)

CUPCAKES

1 large lime, scrubbed (for 1 teaspoon zest and 2 tablespoons juice)
4 large eggs
1 package (18.25 ounces) plain yellow cake mix
1 package (3.4 ounces) vanilla instant pudding mix
1 1/4 cups water
1/3 cup vegetable oil
1 teaspoon coconut flavoring

FILLING

1 can (14 ounces) sweetened condensed milk
1/3 cup Key lime juice

COCONUT MERINGUE (Coconut Whipped Cream recipe below)

1/4 teaspoon cream of tartar
Reserved 3 large egg whites
1/2 teaspoon coconut flavoring
1/3 cup granulated sugar

1. Place a rack in the center of the oven and preheat the oven to 350 degrees F. Line 24 cupcake cups with paper liners. Set the pans aside.

2. Prepare the cupcake batter: With a citrus zester or fine grater, zest the lime and reserve 1 teaspoon. Cut the lime in half and squeeze the juice over a strainer into a small bowl; you should have 2 tablespoons. Set aside. Separate 3 of the eggs, place the whites in a large clean mixing bowl and the yolks in another mixing bowl.

3. Add the remaining egg, cake mix, pudding mix, water, oil, coconut flavoring and lime zest and juice to the yolks. Blend with an electric mixer on low speed for 30 seconds. Stop the machine and scrape down the sides of the bowl with a rubber spatula. Increase the mixer speed to medium and beat 2 minutes more, scraping down the sides again if needed. The batter should look well blended. Spoon or scoop 1/4 cup batter into each lined cupcake cup, filling it two thirds of the way full. Place the pans in the oven.

4. Bake the cupcakes until they are lightly golden and spring back when lightly pressed with your finger, 18 to 22 minutes. Remove the pans from the oven and place them on wire racks to cool for 5 minutes. Increase the oven heat to 450 degrees F.

5. Run a dinner knife around the edges of the cupcake liners, lift the cupcakes up from the bottoms of the cups using the end of the knife, and pick them out of the cups carefully with your fingertips. Place them on a wire rack to cool for 15 minutes before filling.

6. Meanwhile, prepare the filling: Place the sweetened condensed milk and Key lime juice in a small bowl and stir to combine. Spoon the mixture into a pastry bag fitted with a medium tip. Press the tip 1/4 inch into the top center of each cooked cupcake and squeeze the bag to release about 1 tablespoon filling into the cupcake. Scrape off any excess filling with a rubber spatula. Place the cooled cupcakes nearly side by side on a baking sheet.

7. Prepare the meringue: Add the cream of tartar to the reserved egg whites and beat with an electric mixer on high speed until frothy, 45 seconds. Add the coconut flavoring and 1 tablespoon of the sugar. Continue beating on high, adding 1 tablespoon sugar at a time, until the whites form stiff peaks (if you pull the beaters from the meringue, the meringue should extend from the beaters in straight stiff peaks). Spoon 2 tablespoons meringue onto the top of each cupcake and swirl to spread it just to the edges with a short metal spatula or a spoon. Place the pan in the oven. Bake until the meringue is light nutty brown in color, 5 to 6 minutes. Run a dinner knife around the edges of the cupcake liners, lift the cupcakes up from the bottoms of the cups using the end of the knife, and pick them out of the cups carefully with your fingers. Serve at once, or allow the cupcakes to cool 10 minutes, then serve.

Store these cupcakes, in a cake saver at room temperature, for up to 3 days.

COCONUT WHIPPED CREAM

1 pint heavy whipping cream
3-4 TBL powdered sugar
1-2 tsp coconut extract

Whip cream until almost stiff. Add sugar and coconut extract; beat until cream holds peaks.

These cupcakes sound deliciously tangy! I love key lime!! And gah, that filling must be so fabulous. Anything made with sweetened condensed milk is bound to be amazing. Add a little coconut, and I'm beyond in heaven!

Yum until last year I had never had key lime (why, I have no idea since I live in FL) anything. I now realize I've been missing out.

Terrific photos. Btw, I've purchased key lime juice. I believe the name is Nelly & Joe's and found it in the juice section (not produce one) on the top shelf.Thanks for sharing the recipe as I still have a little less than half a bottle of it leftover. :-)

Oooh. *hypnotized by the cupcakes* LOL Lime is one of my favorite flavors these days, so this is definitely getting saved for the future. :)

Sara said...

I love key lime pie, so I'm sure I'd love these cupcakes! The addition of coconut is a nice touch.

Bobbi said...

just a quick question - you said plain yellow cake mix, from what I can see all the cake mixes already have pudding in them, so do you add another pudding mix? I would love to make these this weekend! They look amazing and sound amazing too!

Tracy said...

Bobbi,
I've had no problem making these with cake mixes that already contain pudding. I've added a box of pudding mix in on top of that and they turn out great. Hope you enjoy them!

Bobbi said...

thanks Tracy, I will definitely be making these this weekend! and yes I found the Nellie and Joe's Key Lime Juice at my local grocery store - woohoo! I also know that Williams Sonoma has key lime juice too - but it is a bit pricey.
