Mix all the ingredients together and press into a 10 inch pie plate. Reserve 2 tbsp of the graham crust mixer to use later.
Place in the refrigerator until ready to fill.
For the filling:
Combine the filling ingredients in a saucepan and cook on a medium heat until it boils and thickens, making sure to stir constantly. Continue to mix for 2-3 more minutes until mixture is very thick. You may need to add more cornstarch.
Or you can use the microwave instructions listed above.
Set aside to cool.
*Preheat the oven to 350 degrees
For the Meringue:
In the bowl of a stand mixer fitted with the whisk attachment, beat all the meringue ingredients together until they form stiff peaks.
To Assemble:
Pour the cooled filling into the crust and top with the meringue.
Sprinkle the rest of the crumbs on the top and bake in a 350 degree oven.
Bake until the meringue browns slightly, around 10 minutes but watch it carefully.
