Green Key Lime Pie Bars (Print version)

Tangy, creamy bars combining refreshing key lime with a luscious green hue atop buttery graham cracker crust.

# What you'll need:

→ Crust

01 - 1½ cups graham cracker crumbs
02 - ⅓ cup granulated sugar
03 - 6 tablespoons unsalted butter, melted
04 - Pinch of salt

→ Filling

05 - 4 large egg yolks
06 - 1 can (14 ounces) sweetened condensed milk
07 - ½ cup key lime juice, fresh or bottled
08 - 2 teaspoons key lime zest
09 - 2–3 drops green food coloring, optional
10 - ¼ cup whole milk or half-and-half

→ Garnish

11 - Whipped cream, optional
12 - Additional lime zest or thin lime slices, optional

# How to make it:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving overhang for easy removal.
02 - In a medium bowl, combine graham cracker crumbs, sugar, melted butter, and salt. Mix until texture resembles wet sand.
03 - Press crust mixture firmly and evenly into bottom of prepared pan. Bake for 8 minutes. Remove from oven and let cool slightly.
04 - Whisk egg yolks in a large bowl until slightly thickened, about 1 minute. Add sweetened condensed milk and whisk until smooth.
05 - Stir in key lime juice, zest, food coloring if using, and milk. Mix until fully combined and creamy.
06 - Pour filling over cooled crust and spread evenly. Bake for 14 minutes, or until center is set but still slightly jiggly.
07 - Let cool to room temperature, then refrigerate for at least 2 hours until fully chilled and set.
08 - Lift bars out using parchment overhang. Cut into 16 squares. Garnish with whipped cream and lime zest if desired. Serve chilled.

# Expert suggestions:

01 -
  • The filling strikes that perfect balance between tart and sweet that makes your taste buds dance with each bite.
  • You can make these a day ahead, which means less stress when youre hosting friends for dinner or bringing dessert to a gathering.
02 -
  • Chilling these bars overnight rather than just the minimum two hours dramatically improves both flavor and texture, as the lime notes develop and deepen with time.
  • Adding that quarter cup of milk to the filling makes these bars distinctly creamier than traditional key lime pie, a discovery I made by accident when trying to stretch the filling for a larger pan.
03 -
  • Allow your eggs to come to room temperature before separating, as theyll separate more cleanly and the yolks will whip to a better volume for a silkier filling.
  • If you want to amplify the lime flavor without adding more acidity, rub the lime zest into the granulated sugar with your fingertips before adding it to the crust mixture, releasing the aromatic oils throughout the entire dessert.
