Nutella brownie - Eggless brownie cake - Eggless nutella brownie - Eggless baking

Both of my kids are addicted to Nutella. They love to eat it. My kids were asking for nutella cake for quite some time. I tried Eggless Nutella Chocolate Cake. To them the chocolate powder in it overpowered nutella taste. So they wanted nutella cake. For my first son birthday I was planning to bake chocolate cake with chocolate frosting. but he asked for nutella brownie without any nuts. Birthday boy wins. I followed recipe from here. They enjoyed it till last bit
