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.
07 - Bake for 14 minutes, or until center is set but still slightly jiggly.

09 - Lift bars out using parchment overhang. Cut into 16 squares. Garnish with whipped cream and lime zest if desired. Serve chilled.

# Expert Tips:

01 -
  • The graham cracker crust has this magical sweet-salty thing happening that makes your taste buds do a little happy dance with each bite.
  • You can make these a day ahead which means less stress when youre hosting friends for dinner and need a showstopping dessert that looks like it took way more effort than it actually did.
02 -
  • Overmixing the filling after adding the lime juice can cause the mixture to become too thick too quickly, so use gentle folding motions toward the end.
  • Chilling these bars overnight rather than just two hours creates a flavor that's dramatically more complex, as the lime has time to fully infuse into every molecule.
03 -
  • Line your pan with parchment paper in both directions for handles that make removing the entire dessert effortless before cutting, a trick I only learned after years of struggling with broken bars.
  • When measuring sticky condensed milk, spray your measuring cup with cooking spray first so it slides right out without losing a drop of that precious ingredient.
