Preheat oven to 350 degrees
Place dates in a bowl, and pour the hot water over them.
Allow the dates to soften in the hot water for about 10-15 minutes.
Drain dates and pat dry.
In a food processor mix dates until they are smooth and have no chunks.
Add the flour, egg, egg yolk, vanilla extract, raw honey, coconut oil, cocoa, cinnamon, baking soda, and salt.
Mix until well combined and the mixture is smooth, scraping down the sides as you go, so the ingredients are well incorporated.
Spray an 8x8 inch pan with non-stick cooking spray.
Spread mixture around in the pan, until it is evenly spread.
Place in oven and cook for 20 minutes.
Remove from oven after baking and let cool before cutting in.
