Arrange an oven rack to the center position. Heat your oven to 350℉. Grease two 8" round cake pans and line the bottoms with a parchment paper rounds. Set aside.
In a large bowl, whisk together the flour, salt, baking powder, and baking soda. Set aside.
2 cups whole wheat flour, 1 tsp table salt, 2 tsp baking powder, 1 tsp baking soda
To a small heat proof bowl, add the chopped dates, chocolate, and cocoa powder. Pour the boiling hot water over. Cover the bowl with a glass plate. Let sit for 5 minutes. This softens the dates and melts the chocolate.
2 cups pitted medjool dates, diced, 2 oz unsweetened chocolate, chopped, ¼ cup cocoa powder, 1 ¼ cup boiling hot water
Transfer the dates and chocolate to a blender, using a rubber spatula to scrape the bowl clean. Add vanilla, apple cider vinegar, avocado oil, and eggs. Blend together until very smooth. Stop and scrape down the sides once or twice to ensure everything gets blended well.
1 TBS vanilla extract, 2 TBS apple cider vinegar, ½ cup avocado oil, 2 whole eggs
Pour the wet ingredients into the bowl with the dry ingredients. Gently fold the dry and the wet ingredients together.
Divide the batter between the two pans.
Bake for 20 minutes, rotating the pans halfway through baking. Cake is done when it's set in the center and the sides are slightly pulling away from the pan.
Let them cool for 10 minutes in the pans, then transfer them to wire racks to cool completely. Frost with your favorite frosting (this Date Sweetened Cream Cheese Frosting pairs perfectly!)
