Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan with butter or non-stick spray.

Chop the dates finely and set them aside. If your dates are hard, soak them in warm water for about 5-10 minutes, then drain and chop.

In a bowl, mix together your chopped dates and nuts.

In another bowl, whisk together the flour, sugar, and baking soda until well combined.

In a separate bowl, beat the eggs and then fold them into the dry ingredients.

Gently fold the date and nut mixture into the batter.

Pour the batter into the prepared pan and smooth the top with a spatula.

Bake in the preheated oven for about 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
