Ingredients

  • 1 cup graham cracker crumbs (92 grams)
  • 1/3 cup macadamia nuts (50 grams), finely chopped
  • 6 tbsp salted butter, melted (85 grams)
  • 1 tbsp granulated sugar (13 grams)
  • 4 ounces cream cheese, softened at room temperature (113 grams)
  • 4 large egg yolks, at room temperature
  • 1 (14 ounce) can sweetened condensed milk
  • 2 tbsp lime zest
  • 1/2 cup + 2 tbsp fresh lime juice (142 grams)
  • 1 tsp vanilla extract
  • 1/2 cup cold heavy cream (120 grams)
  • 1 tbsp powdered sugar (8 grams)
  • 1 tbsp vanilla extract
  • Extra lime zest and/or lime slices for garnish

Instructions

  1. Preheat oven to 350°F. Spray a 9×9-inch baking pan with nonstick spray or line with parchment paper.
  2. Pulse or finely chop the macadamia nuts. Mix graham cracker crumbs, macadamia nuts, melted butter, and granulated sugar in a bowl. Press evenly into the prepared pan and bake for 9 minutes.
  3. Beat the cream cheese until smooth and creamy. Add the egg yolks and mix until combined. Add the sweetened condensed milk, lime zest, lime juice, and 1 teaspoon vanilla extract. Mix until just combined.
  4. Pour the filling over the par-baked crust. Bake for 22–24 minutes, until just set with only slight browning at the edges.
  5. Cool completely at room temperature, then cover and refrigerate for at least 4 hours before serving.
  6. To make the whipped cream, beat the cold heavy cream, powdered sugar, and 1 tablespoon vanilla extract until stiff peaks form.
  7. Slice the chilled bars and top each serving with whipped cream and extra lime zest or lime slices. Serve and enjoy.

Notes

  • Chill the bars for at least 4 hours for the best texture and clean slices.
  • Store leftovers in an airtight container in the refrigerator for 4–5 days.
  • Use freshly squeezed lime juice for the brightest flavor.
  • Do not overmix the whipped cream or it may become grainy.
