Preheat your oven to 350°F (175°C).
Grease and line an 8-inch square baking dish with parchment paper.
Place the chopped dates in a bowl and pour the boiling water over them. Stir in the baking soda and let it sit for 10 minutes until the dates are soft.
In a large bowl, whisk together the flour, baking powder, ground ginger, ground cinnamon, ground nutmeg, ground cloves, and salt.
In another bowl, mix the light brown sugar, granulated sugar, melted dairy-free butter, vanilla extract, and plant-based milk until smooth.
Add the softened dates along with the soaking liquid to the wet ingredients and blend with an immersion blender until smooth.
Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
Pour the batter into the prepared baking dish and spread it evenly.
Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes.
