Preheat the oven to 350°F. Line an 8x8 inch baking pan with parchment paper.

Beat the eggs in a mixing bowl until foamy, about 5-8 minutes.

Warm the Nutella in the microwave for 60 seconds, then stir until smooth.

Pour the warm Nutella into the beaten eggs gradually, mixing well until thoroughly combined.

Transfer the batter to the prepared baking pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

Allow the brownies to cool completely before cutting into squares.

Cut into bars and serve. Optionally dust with powdered sugar or add toppings of choice.
