Supermarket Serenade

I want to make some kind of chocolate cake/brownie thing but im haven’t got in any eggs or sunflower oil. I have olive oil, flour, sugar, cocoa power, greek yog, soya yog, bicarb, baking powder, butter, peanut butter, nuts, dried fruit.

Could i make anything with these ingredients? I’ve searched over the net and its been pretty hard to find something.

Does any one have a recipe i could use?

Thanks
