Preheat the oven to 350°F. Prepare a 9-inch cake pan by lining the bottom with a round piece of parchment paper and lightly greasing the sides with cooking spray.

After the dates have softened, transfer them with the milk to a blender or food processor and blend for 15 seconds. Add the eggs, oil and vanilla extract and blend again until just combined, about 5-8 seconds.

In a medium bowl, combine flour, baking powder, baking soda, and salt. Pour the date and egg mixture into the dry ingredients and fold together until combined.

Transfer the batter to the prepared cake pan. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Remove from the oven and allow the cake to cool in the pan for about 20 minutes.

Flip the cake out of the pan, peel off the parchment paper, and transfer it to a wire rack.

Slowly pour date syrup over the warm cake, using the back of a spoon to spread it evenly. Enjoy warm or allow to cool completely and store covered at room temperature.
