Kitchen Equipment You’ll Need

• 8”x8” baking dish
• Parchment paper
• Mixing bowls
• Electric mixer or whisk
• Zester or grater

Ingredients

For the Shortbread:

• 1 1/2 sticks salted butter, room temperature
• 1 1/2 cups all-purpose flour
• 1/3 cup powdered sugar

For the Topping:

• 2 eggs, room temperature
• Juice of 3-4 key limes or regular limes (about 1/4 cup), strained
• 1 1/4 cups granulated sugar
• 1/4 cup all-purpose flour
• 2 teaspoons cornstarch
• 1 teaspoon vanilla extract
• 1/4 teaspoon baking powder
• 1/8 teaspoon salt
• 1 teaspoon key lime zest
• Powdered sugar and/or extra lime zest for garnish

Step-by-Step Instructions

1. Preheat your oven to 350˚F. In a mixing bowl, combine the shortbread ingredients until crumbly. Press the mixture into an 8”x8” baking dish lined with parchment paper, extending it 1/2” up the sides. Bake for 15-20 minutes, or until lightly golden.
2. In another bowl, beat the eggs until foamy. Add the lime juice, granulated sugar, flour, cornstarch, vanilla, baking powder, and salt. Mix until smooth, then stir in the lime zest. Pour this mixture over the warm crust.
3. Return the dish to the oven and bake for 25-28 minutes, or until the center is set and no longer jiggly. Allow to cool in the refrigerator for at least 1 hour before garnishing with powdered sugar and extra lime zest. Cut into 16-25 squares to serve.

Tips for Success

For best results, ensure your butter is at room temperature to achieve a perfectly crumbly shortbread. Be patient and allow the bars to fully chill before slicing to ensure clean, neat squares.

Additional Tips and Variations

If you prefer a sweeter topping, add a bit more sugar. You can also add a hint of coconut to the shortbread for a tropical twist. For those who love extra tartness, increase the lime zest in the topping.
