Preheat your oven to 350°F. Line an 8×8-inch pan with parchment paper. Leaving a little “overhang” on the sides makes it easy to lift the whole block out later.
Scrape every last bit of the Nutella jar into a bowl. Whisk in the two eggs until the mixture is glossy and looks like liquid silk.
1 jar Nutella , 2 large Eggs
Sift in your flour. Use a spatula to gently fold it in. Stop immediately when the white streaks disappear. Over-mixing leads to tough, bready brownies.
½ cup All-Purpose Flour
Spread the batter evenly into your pan. Bake for 25–30 minutes.
A toothpick should come out with a few moist crumbs. If it’s clean, they’re overdone!
Notes
The Baking Pro-Tip
To get that iconic crinkled top, give the pan a firm “thud” on the counter the second you pull it out of the oven. This collapses the air pockets and creates those beautiful cracks.Wait for it: These brownies are high in healthy fats from the hazelnuts. They must cool completely in the pan to set. If you cut them while hot, they’ll be delicious, but they won’t hold their shape. Patience is the final ingredient!
