Chocolate brownie paleo style

This chocolate brownie cake was the result of experimenting from ingredients I had to hand.  I don't think quantities are too critical.

Ingredients

12 soft, dried figs
600g sweet potatoes
3 tbsp peanut butter
2 tbsp cocoa powder
1 tbsp agave syrup
1 tsp baking powder
handful cocoa nibs
1 egg

Peel, cop and boil the sweet potatoes until soft, then drain and mash.
Blend the figs in a food processor.
Mix all the ingredients in a bowl.  Grease and line 2 1lb loaf tins.  Put half of the mixture in each.
Bake at 170 degrees C for 25 mins or until firm.
