Black bean brownies

This recipe is converted from the Healthy Hybrid.  Similar concept to the magic bean chocolate cake which uses red kidney beans in place of flour.  I have yet to try it but thought I'd post anyway

Ingredients

2 cup cooked black beans, drained of all liquid - could use a can.
2/3 cup rapadura sugar or sweetner of choice
1/3 cup raw cacao powder, cocoa, or carob powder
2 tbsp coconut oil, or butter
3 eggs,
1 1/2 tbsp vanilla extract
1/4 tsp sea salt
walnuts (optional)

Do

1.  Preheat oven to 180 degrees and prepare a rectangular slice pan/ dish (grease or line with baking paper) 

2.  Blend ingredients other than walnuts together with 20 seconds sp 5 or until well blended
3.  Pour into greased 8"x8" pan. top with walnuts for decoration if you'd like

4.   Bake in the oven maybe 15 minutes. When the top starts to crack, they're golden and cooked.
