Mix graham cracker crumbs, sugar, and melted butter for the shortbread base. Press into the bottom of a 9-inch springform pan and bake for 10 minutes. Let it cool.
In a food processor, blend avocados, lime juice, sugar, and Norman's Kosher Cholov Yisroel Cream Cheese until smooth. Pour over the cooled crust.
Chill the cheesecake in the refrigerator for at least 4 hours or overnight.
For the lemon curd topping, whisk sugar, butter, eggs, lemon juice, and zest in a saucepan over medium heat until thickened. Let it cool, then spread over the chilled cheesecake.
Refrigerate the cheesecake again for another 2 hours before serving. Enjoy your Avocado Lime Dream Cheesecake!
