Step 1

Heat oven to 350°F and spray the bottom of 9x9-inch baking dish.

In a bowl combine crust ingredients and stir until well combined and crumbly, then press it into the bottom of baking dish and bake for 20 minutes, remove from the oven and let it cool completely.

Mix cream cheese and powdered sugar until smooth and creamy. Fold in 1 cup whipped topping and 1/2 teaspoon vanilla and spread over cooled crust. Set in the fridge.

In medium sauce pan stir together sugar and corn starch, stir in key lime juice and slightly beaten egg yolks, add butter and bring mixture to a very controlled simmer over medium-low heat stirring almost constantly until thickened. It should be able to coat the back of a metal spoon. Remove from heat, cover with plastic foil and refrigerate for at least 2 hours.

When key lime custard is cooled completely, add a few drops green food coloring and mix it well. Stir in 1 1/2 cups whipped topping and spread onto cheesecake layer.

Top with 1 cup whipped topping and sprinkle chopped nuts. Set in the fridge for at least 4-5 hours or overnight. You can place it in the freezer and serve like frozen dessert (It defrosts fairly quickly).
