How to make key lime cupcakes:

1. First, make the cupcake batter as the box says with the exception of the water. This is where all that flavor comes from.

You are going to substitute ½ cup of the water with ½ cup lime juice. This is the secret to that amazing lime flavor and tangy taste. No one will guess this started with a cake mix!

2. Second, get your muffin pan ready and add the liners. Don’t overfill these or you will have a huge mess.

About half way is best and I use a cookie scoop to make sure they are all equal. Plus, it speeds up the process too.

3. Bake those yummy cupcakes and let cool.

Finally, it is time to make the frosting. 

This will help pass the time while the cupcakes cool. The frosting is really easy but so creamy and decadent.

1. Get a large bowl or use your stand mixer. Mix the butter until it is fluffy and add the lime juice and green food coloring.

2. Second, add the powdered sugar but not all at once. This can get messy so it’s best to add a cup at a time.

3. Once, the sugar and butter are mixed really well, add lime zest and mix again.

Your cupcakes should be cool by now and ready to decorate. You can either use a Wilton throw away bag or a ziploc bag if you don’t have the piping bags. Just cut the corner off and frost each cupcake.

More tasty ideas: 

  • Sprinkle graham cracker crumbs on top.
  • Make mini cupcakes instead of regular size.
  • Garnish with a lime slice on each cupcake.
