Green Key Lime Pie Bars (Printable)

Tangy, creamy bars with fresh key lime zest and a buttery graham cracker base. A refreshing citrus dessert perfect for any occasion.

# 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 to 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

# Directions:

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

# Expert Hints:

01 -
  • The perfect balance of sweet and tangy makes these bars impossibly addictive - I once watched my usually reserved father-in-law eat four in one sitting.
  • The make-ahead nature means you can focus on enjoying your guests rather than frantically plating dessert at the last minute.
02 -
  • Overmixing the filling can incorporate too much air and cause cracks - I learned this the hard way when rushing to make these for a potluck.
  • The bars might look underbaked at 14 minutes, but they continue to set as they cool - pulling them too late makes them rubbery rather than creamy.
03 -
  • For the most vibrant flavor, zest the limes before juicing them - the oils are most potent when the fruit is still intact.
  • Adding that quarter cup of milk to the filling creates a lighter texture that makes these bars distinctly different from traditional key lime pie.
