Preheat oven to 325 degrees F. Grease a square glass pan. In a medium bowl, mix ingredients. This will be a thick cookie crust; press onto bottom of pan. Place in oven to pre-bake the crust. Bake for 15 minutes or until lightly golden brown. Remove from oven and set aside to cool.
FILLING:
In a medium bowl, beat the ingredients for the filling until well combined. Pour the mixture evenly over the pre-baked crust and bake again for about 15-20 minutes or until set. Let cool. Store in fridge or freezer in an airtight container.
