Best Brownies without flour

I made these brownies for a friend who has stopped eating flour.  I received so many great complements on them.

Brownie Ingredients:
2 cups cooked quinoa, loosely packed
1/3 cup milk
4 eggs
1 teaspoon vanilla
3/4 cup butter, melted and slightly cooled
1 1/2 cups white sugar
1 cup unsweetened cocoa powder
1 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon fine sea salt



Preheat the oven to 350 degrees. Grease one 9x13 pan.

Combine the milk, eggs and vanilla in the blender or food processor and pulse a few times to combine. Add the cooked quinoa and the butter and puree until completely smooth. Stop the machine as needed to scrape the sides and make sure everything is well mixed. This will be a thick and creamy consistency once the quinoa is pureed. (You should not see any little beads of quinoa in the pureed mixture.) Whisk together the dry ingredients in a mixing bowl and add the contents from the blender. Stir until well combined.

Put the batter in the cake pan and bake on a center oven rack for 28-30 minutes, until a toothpick inserted comes out clean. Remove the cake from the oven and let cool.  I just let it cool in the pan.  I also frosted them with a basic frosting recipe which I will have to post at a later time.
