Preheat oven to 350 F and prepare a 9x13 inch loaf pan with parchment paper and non-stick spray.
Place all crust ingredients into a food processor and pulse until combined. Press the crust evenly into the bottom of the prepared pan. Bake for 12-15 minutes.
All the while, prepare your filling by whisking all filling ingredients together until smooth. Remove crust and pour the filling over the crust while it's still hot.
Reduce heat to 325F and continue baking for another 15-20 minutes. The filling should still be giggly but solid to the touch.
Let cool completely before cutting into squares and serving. Best if chilled before serving.
