Preheat oven to 325°F.

Lightly grease a 13x9x2-inch baking pan.

Transfer the mixture to the prepared pan and pat down evenly with your hands.

Pour the sweetened condensed milk over the top to cover, using a spatula to spread if necessary.

Bake for 30-35 minutes, or until lightly golden. Do not under cook or they will likely crumble when cut.

Cool to room temperature, cover tightly with plastic wrap, and allow to set overnight before cutting and serving.
