These chocolate hazelnut brownies, aka nutella brownies, are ooey, and gooey, oh so fudgy, and a family favorite! I remembered the half empty jar of Justin’s chocolate hazelnut spread that was getting lonely in the pantry and the perfect gooey brownies recipe was created!

How to make Hazelnut Brownies

Preheat oven to 350°F oven. Line an 8 x 8 square baking pan with parchment paper or foil and spray with cooking spray.

In a small bowl, combine butter and unsweetened chocolate. Heat on HIGH in the microwave for 1 minute. Stir until chocolate is melted. I have a 1000 watt microwave, so you may need to adjust accordingly.

In a large bowl, beat chocolate mixture and sugar together with a hand mixer.

Expert Tips

  • I used Justin’s to make these brownies lactose-free. Nutella and Nocciolata both contain dairy.
  • This recipe can easily be doubled and baked in a 9 x 13-inch baking pan for 30 to 40 minutes.
  • All ovens cook differently so baking time may vary. Check at the lowest time and adjust accordingly.

FAQ’s

How do I know when hazelnut brownies are done baking?

Use a toothpick or a cake tester inserted into the center of the brownies. If it comes out slightly sticky with a few moist crumbs (not wet batter), the brownies are done. Overbaking can result in dry brownies.

How do you store homemade brownies?

Allow the hazelnut brownies to cool completely in the baking pan, then transfer to an airtight container. Place a piece of parchment paper or plastic wrap between layers of brownies to prevent them from sticking together.
Store at room temperature for up to 2 days, or in the refrigerator for up to 4 days. Bring up to room temperature before serving.
