Instructions
Preheat oven to 350 degrees. Lightly spray a 9 x 13 pan with non-stick cooking spray. If you want a thicker bar, use a 9-inch square pan.
To make the graham cracker crust: in a medium bowl, combine graham cracker crumbs, melted butter, and sugar. Press the graham cracker mixture firmly into baking pan. Firmly press down with hands.
Bake the crust for 7-8 minutes or until lightly golden. Let cool.
Turn oven temperature down to 325 degrees.
To make the filling: whisk together sweetened condensed milk, heavy cream, egg yolks, lime juice, and 2 teaspoons lime zest -- reserving 1 teaspoon of lime zest for garnish. Pour filling over cooled crust.
Place the baking pan into a large pan to make a water bath. Pour enough water into the larger pan to come halfway up the sides of the smaller baking pan. Bake for 19-24 minutes at 325 degrees. The filling is done when it no longer jiggles in the center. Remove from water bath and set it on a rack to cool for 1 hour, then refrigerator until chilled.
To make whipped cream: Beat whipping cream until soft peaks form. Add desired powdered sugar and whip for 30 seconds longer.
Cut the bars into squares and serve chilled with a dollop of whipped cream and fresh lime zest.
