Preheat oven to 350F and lightly oil a 8x8x2" dish with pam.
-1c ground almonds/almond meal (or ground pecans)
-1/2c unsweetened cocoa powder
-1/4c arrowroot powder
-1/2c agave nectar (or 1/4c splenda)
-2 whole omega-3 eggs
-6T walnut oil
Mix well in bowl. Transfer to baking dish and spread out evenly. Bake 20 minutes or until toothpick comes out clean.
Voila...guiltless yum! No flour! No butter! No refined sugar! Tons of fiber, w-3 fatty acids, and antioxidant rich cocoa! Woot! 
Well, guiltless only if you have 1 slice (1/12 of dish using pecans and agave nectar = ~ 200C). I used almonds and splenda, but must have consumed 9/12 today--yikes! 
Damn, didn't take a picture.
Good stuff though.
