Preheat the oven to 350°F (175°C).
Prepare the dates by making a slit down one side and removing the pit.
In a bowl, mix feta cheese, Parmesan cheese, walnuts, olive oil, and black pepper until well combined.
Stuff each date with the cheese mixture, pressing lightly to ensure they are well-filled.
Arrange the stuffed dates on a baking sheet and drizzle with honey.
Bake in the preheated oven for about 15-20 minutes until heated through and slightly golden.
Remove from the oven and let cool briefly before serving.
