For the most luscious texture, use high-quality, full-fat ricotta and cream cheese. Do not rush the draining of the ricotta; this step is crucial for achieving the right consistency. Feel free to experiment with other nuts, such as almonds or walnuts, in the crust and garnish. A touch of honey or maple syrup can be added to the filling for an extra layer of sweetness. The bars can be stored in the freezer for up to a week, making them perfect for make-ahead entertaining.
