Preheat oven to 350 degrees. Grease two 8 inch round or square baking pans. Line with parchment.
Combine milk, eggs, and vanilla in a blender or food processor. Add ⅔ cups of cooked quinoa, butter, applesauce and walnut oil. Process until smooth.
Whisk together coconut palm sugar, cocoa, baking powder, baking soda and salt in a medium bowl. Add milk mixture and combine until well blended. Divide between pans and bake for 40 to 45 minutes. (Or, if cooking in individual serving size pans, cook for about 28 minutes) You know the cake is done when a toothpick comes out clean. Remove from oven and allow to cool completely prior to serving.
Frost if desired.
