Black Bean Brownies (grain and processed sugar free)

I found a recipe for black bean brownies on the internet which I really liked, but foolishly did not bookmark it or save a copy, and then forgot where I'd found it, and forgot the recipe as well. So this is my attempt at figuring out a recipe for myself, which avoids most of the things which really mess with my health. These are moist and fudgy (at least if you don't overcook them) and delicious. I slice these about 1 inch square and freeze them, otherwise they would disappear extremely fast.

1 ½ cups cooked black beans
16 dates, soaked overnight and drained
2 eggs
4 tbsp cream
4 tbsp honey (or maple syrup)
3 heaping tbsp hazelnut meal
3 tbsp cocoa
½ tsp vanilla essence (optional)
2 tsp baking powder

Preheat oven to 180C and line a small baking dish with baking paper. Combine in the food processor until smooth. Pour into tray and smooth the top. Bake for 30 minutes, slice then leave in tray to cool for a few minutes before turning out.

This recipe is veganisable if you sub maple syrup for the honey, coconut cream or nut milk for the cream, and 2 tbsp flaxseed meal mixed with 5-6 tbsp warm water and left to gel for a few minutes for the eggs.
