For the Super Soft Nutella Brownies, cut the butter and chocolate into small pieces, melt together slowly in a saucepan.
Beat the eggs and sugar, then slowly add the chocolate-butter mixture and Nutella. Finally, fold in the flour, baking powder and hazelnuts.
Empty the mixture into a baking pan lined with baking paper or into a baking tray and smooth it out. Bake in the preheated oven at 170°C for about 20 to 25 minutes.
Allow the Super Soft Nutella Brownies to cool slightly and cut into small cubes, sprinkle with a little powdered sugar and serve immediately.
Preparation Tip:
Serve the Super Soft Nutella Brownies with the chocolate sauce and with the mango salad.
