Most of us have stared at an almost-empty Nutella jar, wondering whether to save the last bit for toast or eat it straight. Today, you can use up the whole jar to make the richest, fudgiest brownies you’ve ever tried.

Using the whole jar means no waste and extra flavor. Here’s why just three ingredients can make a dessert that tastes like it came from a bakery.

The Ingredients

  • Nutella: Our source of fat, sugar, and cocoa.
  • Eggs: For structure and lift.
  • All-Purpose Flour: To provide the necessary crumb.

The Science Behind the Simplicity

Baking is all about chemistry, and Nutella is already a ready-made emulsion. Since the sugar and hazelnut oils are blended together, you don’t need to cream butter or worry about grainy batter.

The eggs help the brownies rise. When you whisk them into the thick Nutella, they trap air that expands as the brownies bake. The flour adds just enough structure to keep the brownies from turning into a gooey mess, without making them cake-like.

Step-by-Step Instructions

  1. First, preheat your oven to 350°F. Line an 8×8-inch pan with parchment paper, leaving some extra hanging over the sides so you can lift the brownies out easily when they’re done.
  2. Scoop out every bit of Nutella from the jar into a bowl. Add the two eggs and whisk until the mixture is smooth and shiny.
  3. Sift in the flour and gently fold it in with a spatula. Stop as soon as you don’t see any more white streaks. If you mix too much, the brownies will turn out tough.
  4. Spread the batter evenly in your pan and bake for 25 to 30 minutes.
  5. Check with a toothpick—it should come out with a few moist crumbs. If it comes out clean, the brownies are overbaked.

The Baking Pro-Tip

For a classic crinkled top, firmly tap the pan on the counter as soon as you take it out of the oven. This helps create those signature cracks.

Let the brownies cool completely in the pan, so they set properly. If you cut them while they’re still warm, they’ll taste great but won’t hold their shape. A little patience makes all the difference.

Ingredients
  

  • 1 jar Nutella 13 ounce
  • 2 large Eggs
  • ½ cup All-Purpose Flour

Instructions
 

  •  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.

  • 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!
