Ingredients:
For the Lime Curd:
- 3 eggs
- ¾ cup sugar
- ¼ teaspoon salt
- ½ cup lime juice
- 1 tablespoon lime zest
- ¾ cup unsalted butter
- Neon green food coloring (or green and yellow food coloring)
For the Cupcakes:
- 6 tablespoons unsalted butter, softened
- ¾ cup sugar
- ⅓ cup egg whites (about 3 egg’s worth)
- ⅓ cup vanilla Greek yogurt
- ⅓ cup milk
- ¼ cup lime juice
- 1 teaspoon vanilla extract
- 2 teaspoons lime zest
- Green food coloring
- 1 ½ cups flour
- 2 teaspoons baking powder
- ½ teaspoon salt
For the Frosting:
- 1 cup unsalted butter, softened
- 1 teaspoon vanilla extract
- 1 teaspoon salt
- 4 cups powdered sugar
- 3-4 tablespoons milk
- Neon green food coloring (or green and yellow food coloring)

Directions:
Prepare the Lime Curd: Start by making the lime curd, as it needs time to chill and set. In a small saucepan, combine the eggs, sugar, salt, lime juice, and lime zest. Whisk until smooth. Heat over medium heat until the mixture begins to bubble. Stir constantly until the mixture thickens, then remove from heat. Strain the curd mixture into a medium-sized bowl to remove zest and any cooked egg pieces. Add butter and food coloring, whisk until smooth, then cover with plastic wrap touching the curd’s surface. Chill in the fridge for about an hour to set.

Prepare the Cupcakes: Preheat your oven to 350 degrees Fahrenheit and line your cupcake pan(s) with cupcake liners. In a stand mixer, cream together softened butter and granulated sugar. Add egg whites and mix until light and fluffy. Add vanilla, lime zest, food coloring, yogurt, milk, and lime juice, mixing until combined. Gradually add salt, baking powder, and flour, mixing until well combined. Divide the batter equally among the cupcake liners (about ½-⅔ full) and bake for 14-16 minutes, or until a toothpick inserted in the center comes out clean. Allow cupcakes to cool completely.

Prepare the Frosting: In the stand mixer, combine softened butter, salt, and vanilla. Cream until smooth. Add about half of the powdered sugar and half of the milk, mixing on low until combined. Add the remaining powdered sugar and mix until smooth. If the frosting appears dry, add the remaining milk and mix again. Add your desired food coloring and mix thoroughly.

Assemble the Cupcakes: Once cupcakes have cooled and the lime curd has set, it’s time to decorate. Transfer the frosting to a piping bag (or ziplock bag) fitted with a large round tip, and set aside. Transfer the lime curd to another piping bag (or ziplock bag), and set aside. Using a small ice cream scoop or teaspoon, scoop out the center of each cupcake. Cut a hole in the tip of the lime curd bag and carefully pipe enough curd into each cupcake to fill it without overflowing. Gently replace the reserved cupcake piece on top of the lime curd to cover it and give the frosting something to grab onto. With the frosting bag, start on the outside edge of the cupcake and squeeze the frosting carefully to go around the cupcake and then spiral inwards and up to cover the curd and create a mound. Repeat with the remaining cupcakes.

Instructions
Directions:
- Begin by making the lime curd. It needs to chill in the refrigerator in order to set.
- In a small sauce pan, combine the eggs, sugar, salt, lime juice and zest. Whisk until smooth.
- Heat over medium until the mixture begins to bubble. Then stir constantly until the mixture thickens. Remove from the heat.
- Set out a medium sized bowl and strain the curd mixture – this should capture most of the lime zest and any potential cooked egg pieces.
- Add in the butter and food coloring and whisk until the butter has melted and the mixture is smooth. Cover with plastic wrap so that it is touching the top of the curd to prevent a film from forming during the chill time. Allow to cool in the fridge for about an hour in order to set up.
- While making the curd and/or during the chill time, make the cupcakes.
- For the cupcakes: preheat the oven to 350 degrees and line your cupcake pan(s), set aside.
- In the bowl of a stand mixer, cream together the softed butter and granulated sugar.
- Add in the egg whites and continue to mix on medium speed for an additional 2 minutes or until light and fluffy looking.
- Add in the vanilla, lime zest, food coloring, yogurt, milk and lime juice. Mix until combined.
- Finally, combine with the salt, baking powder and flour. Mix on low speed for about a minute and then medium speed for another minute until thoroughly combined. Stop and scrape the sides if needed and mix again.
- Divide equally among the cupcake liners – fill each cavity about ½-⅔ full. Bake for approximately 14-16 minutes or until a toothpick inserting in the center of one cupcake comes out clean. Allow to cool completely before decorating.
- For the frosting: in the bowl of a stand mixer, combine the softened butter, salt and vanilla. Cream until smooth.
- Add in approximately half of the powdered sugar and half of the milk. Mix on low speed until combined. Add in the remaining powdered sugar and mix until smooth.
- Bump up the speed and mix for an additional minute until the frosting is light and fluffy – should be a stiff consistency – do not add the remaining milk unless the frosting still looks dry at this point. Mix again.
- Add in your desired food coloring and mix thoroughly.
- To assemble: Once the cupcakes have cooled and the curd has set up, it’s time to decorate. Transfer the frosting to a piping bag (or ziploc bag) fitted with a large round tip (or just a hole cut in the end), set aside. Transfer the lime curd to a piping bag (or ziploc bag), set aside.
- Using a small ice cream scoop or teaspoon, scoop out the center of each cupcake. Cut a hole in the tip of the lime curd bag and carefully pipe enough in the void of each cupcake to fill but not overflow. Gently replace the reserved cupcake piece on top of the lime curd to cover the curd and give the frosting something to grab on to.
- With the frosting bag, begin on the outside edge of the cupcake and squeeze the frosting carefully to go around the cupcake and then spiral inwards and up to cover the curd and create a mound. Repeat with the remaining cupcakes.
