Key Lime Fudge
Using a medium-sized heat-safe mixing bowl, add the white baking chips and the sweetened condensed milk. Heat in the microwave for 45 seconds, stir and continue heating for 15-second intervals until the mixture is smooth.
Add the lime zest and the key lime juice. Stir until the mixture is smooth.
Evenly spread the fudge over the graham crust. Evenly sprinkle the 1 teaspoon of reserved lime zest on top of the fudge. Loosely cover and chill in the refrigerator for 2 hours to set.
Grasp the edges of the parchment paper and lift the fudge out of the pan onto a cutting board.
Carefully slice the fudge into 36 (1½-inch x 1½-inch) squares. Keep the fudge refrigerated until you are ready to serve.
If you need to crush your graham crackers, you can toss them in the food processor or crush them in a Ziploc with a rolling pin until they are fine crumbs.
Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your crust as the suggested baking time approaches.
If you are using fresh-squeezed key lime juice, be sure to strain the juice before adding it to the fudge.
If you prefer, you can also sprinkle a ½ teaspoon of crushed graham crackers on top of the key lime pie fudge along with the lime zest.
