Easy Key Lime Cupcakes

Last year a friend of mine brought a delicious Lime Cake to a church gathering and I about died and went to heaven! It was fluffy, delicious, moist, and somehow strangely refreshing! The frosting on top was also AMAZING, and so I did what any friend would do in this instance and I BEGGED her for the recipe. Lucky for me, my friend likes to share, and so the very next day she sent me her recipe.

I was excited to make these for my family party that same weekend, but I wanted to make them into cupcakes since they are more convenient when it comes to feeding a crowd. I looked at the ingredient list for this recipe and I made a shopping list of all the things I would have to buy at the grocery store. The list was quite extensive, so even though I knew she had achieved cake perfection with this recipe, the wheels in my head started turning on how I could replicate this recipe  but make it even easier.

So I did just that.

And you guys.

This lime cupcake recipe is amazing!

What’s The Difference Between Key Limes and Regular Limes

Key limes (which are also called West Indian or Mexican limes) get their name because they were previously only grown domestically in the Florida Keys.  Now regular limes (also called Tahitian or Persian limes) are predominately grown in the U.S.  Key limes have a slightly yellow color while regular limes are green in color.  Key limes also smaller, have more seeds and have a more tart flavor than traditional limes.

How to Make Key Lime Cupcakes

One of the things I love most about this recipe is that it doesn’t call for any strange ingredients, and you might have everything at home right now!

  1. Make your cake mix according to the box EXCEPT substitute half of the required water with lime juice.  For example, if the box require one cup of water, use 1/2 of water and 1/2 cup lime juice.  You’ll also add in the one box of lime jello to the cake mix.
  2. Spray your cupcake pan with cooking spray or use colorful cupcake liners
  3. Fill each cupcake liner about 2/3 full with batter
  4. Cook according to the time and temperature on the cake box
  5. Frost the cupcakes once the cupcakes have completely cooled

Tips for Making Key Lime Cupcakes

  • Whenever I make cupcakes, I always use my large scoop to put the batter into the cupcake liners. Not only is this a more mess-free option, it also ensures your cupcakes come out the same size.
  • When I pull my cupcakes out of the oven, I leave them in the cupcake pans for an additional 5 minutes so they completely finish baking. Then, I let them cool completely on a cooking rack before I frost them.

Can Your Freeze Lime Cupcakes

  • You can store an unfrosted lime cupcakes in an airtight container and they should stay fresh on the counter at room temperature for about a week.  I typically use a large Ziploc storage bag because they’re easy for my kids to open and close.
  • If you don’t plan on eating the cupcakes cake within a week, then you’ll want to store them in the freezer.  Make sure you use a Ziploc freezer bag and then write the date on the outside of the bag so you can remember when you put them in the freezer.  You can keep the cupcakes frozen for about 2 months.
