Preparation Steps

• Preheat the oven to 350ºF (175°C) and line an 8x8 inch brownie pan with parchment paper.
• Place the eggs in a mixer's bowl and beat for 5 to 8 minutes, or until the eggs have tripled in size and are pale yellow. (If using a handheld mixer, this may take up to 10 minutes on high speed.)
• Warm the Nutella in the microwave for about 60 seconds until it is smooth and runny. Remove and stir well.
• Slowly pour a thin stream of the warm Nutella into the whipped eggs while continuously beating on low speed until the mixture is just combined. Do not overmix.
• Transfer the batter gently into the prepared brownie pan.
• Bake for 30 to 35 minutes, or until a toothpick inserted near the center comes out with moist crumbs attached (not wet batter).
• Remove from the oven and let the brownies cool completely in the pan before attempting to cut.
• Dust with powdered sugar (optional), cut into 9 squares, and serve.
