Nutella Chocolate Brownies

I would say brownies is easy to make but I have not come across a recipe that I really like.  The last time when I bake one, my lover boy told me please not add nuts into brownie again and I knew he wouldn't like dried fruit as well.  I alway believe that when baking chocolate cake or slices, using cocoa powder is not as good as using real chocolate.  And I want to proof that I'm wrong so I'm trying to make one using cocoa powder instead of melted chocolate but I must put in chocolate bits just in case it doesn't work.  When it is all ready to go into the oven, I couldn't stop myself putting some Nutella on top.  I know I have got the idea from somewhere.  Then I find that it is from kitchenbelleicious's Nutella Coconut & Caramel Brownies Although this brownie is made for my son, my husband loves it the most and I've made the boys happy.
