Ingredients

Ingredients for cake:

1 box White Cake Mix + box ingredients
½ cup Lime Juice

Ingredients for frosting:

1 cup Butter
6 cup Powdered Sugar
6 tbsp Lime Juice
2 tsp Lime Zest
1 drop Green Food Coloring

Instructions

Make the Cupcakes:

Preheat the oven according to the directions on the white cake mix box. Line 24 muffin cups with cupcake liners.
Prepare the cake mix according to the package directions, replacing ½ cup of the required water with ½ cup fresh lime juice.
Divide the batter evenly among the cupcake liners, filling each about halfway full.
Bake for 16–18 minutes, or according to the package directions, until a toothpick inserted into the center comes out clean.
Let the cupcakes cool in the pans briefly, then transfer them to a wire rack to cool completely before frosting.

Make the Frosting:

In a large mixing bowl, beat the softened butter until smooth and creamy.
Add the lime juice and green food coloring. Beat until combined.
Gradually add the powdered sugar, about 1 cup at a time, beating well after each addition.
Add the lime zest and continue beating until the frosting is light and fluffy.
Transfer the frosting to a piping bag or spread it over the completely cooled cupcakes with a knife or spatula.
Serve immediately or store covered until ready to serve.

Notes

Fresh lime juice provides the best flavor and also allows you to use the lime zest in the frosting.

Make sure the cupcakes are completely cool before frosting them.

The Great Value white cake mix requires egg whites, water, and vegetable oil; those box ingredients are included in the estimated recipe cost.

Store leftover cupcakes in an airtight container.
