Place the Nutella and eggs in a medium bowl and whisk until smooth and well blended. Add the flour and whisk until blended.
Pour batter into a 9 x 9 baking pan lined with parchment paper.
Bake about 10-12 minutes until a knife inserted comes out almost clean with just a few crumbs clinging.
While the brownies are baking, make the crunch. First microwave the nutella in a glass bowl for about 30 seconds to one minute to make it easier to mix. Add in the cereal and mix thoroughly until cereal is covered with nutella.
Once brownies are out of the oven, spread the crunch evenly on top of the brownies.
Let brownies cool completely and set before serving.
