Ingredients

1 1/2 cups graham cracker crumbs

1/3 cup granulated sugar

1/2 cup unsalted butter, melted

1 cup sweetened condensed milk

1/4 cup brown sugar

2 tablespoons butter

1 1/2 cups white chocolate chips

1/2 cup heavy cream

1/4 cup fresh key lime juice

1 tablespoon key lime zest

4 oz cream cheese, softened

Extra lime zest for garnish (optional)

Lime slices or twists for garnish (optional)

Instructions

  1. Preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
  2. In a bowl, combine the graham cracker crumbs, granulated sugar, and melted butter until the mixture resembles wet sand.
  3. Press the crust mixture firmly into the prepared pan and bake for 8 to 10 minutes. Allow the crust to cool completely.
  4. In a saucepan over medium heat, combine the sweetened condensed milk, brown sugar, and butter. Stir continuously until smooth, glossy, and slightly thickened.
  5. Pour the middle layer over the cooled crust and spread evenly. Let it cool.
  6. Heat the heavy cream until hot but not boiling. Pour it over the white chocolate chips and let sit for 1 minute before stirring until smooth.
  7. Add the softened cream cheese, key lime juice, and key lime zest to the white chocolate mixture and stir until creamy and smooth.
  8. Pour the white chocolate key lime mixture over the middle layer and spread evenly to the edges of the pan.
  9. Refrigerate for at least 4 hours or overnight until fully set.
  10. Lift the bars from the pan using the parchment paper, slice into squares, and garnish with extra lime zest or lime slices before serving.

Notes

Regular lime juice can be substituted for key lime juice if needed.

For extra texture, add chopped macadamia nuts or pecans to the crust.

Toasted coconut makes a delicious tropical topping.

Store bars in an airtight container in the refrigerator for up to 4 days.

Freeze bars for up to 2 months with parchment paper between layers.

For clean slices, chill thoroughly and wipe the knife clean between cuts.
