Variations Ideas

• Frosting – We love the key lime buttercream frosting, but you can also make a Homemade Cream Cheese Frosting. Add Key Lime Juice and Key Lime Zest for delicious flavor. These cupcakes would also be delicious with a Cream Cheese Glaze.

How to Make Key Lime Cupcakes

Step 1 – Whisk the cupcake batter as the box says with the exception of the water. This is where all that flavor comes from.

Step 2 – Second, get your muffin pan ready and add the liners. Don’t overfill these or you will have a huge mess. Bake those yummy cupcakes and let cool.

Step 3 – Get a large bowl or use the bowl of a stand mixer. Mix the butter until it is fluffy and add the lime juice and green food coloring. You can also use an electric mixer on medium speed to mix the ingredients.

Step 4 – Add the powdered sugar but not all at once. This can get messy so it’s best to add a cup at a time. Once, the sugar and butter are mixed really well, add lime zest and mix again.

• Step 5 – 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.
