Soft and chewy chocolate hazelnut brownie bars, made with creamy hazelnut-cocoa spread, flaky sea salt and crunchy hazelnuts.

These dense, rich chocolate hazelnut bars have a short list of ingredients in the recipe (and no flour or dairy), putting the spotlight directly on the main characters.

Chocolate and hazelnuts. Like Bogie and Bacall, they made for each other. The story goes that gianduja, a sweet chocolate-hazelnut paste, was invented by chocolatiers in Turin, after Napoleon blocked the cacao trade in 1806. Hazelnuts helped the scarce chocolate go a lot further.

Hundreds of years later, a pastry chef named Pietro Ferrero came up with the process for manufacturing the thick spread, making it accessible and affordable for the masses.

This recipe is adapted from a nut butter blondie recipe I bookmarked months ago, but when I decided to make it I turned to my favorite spread instead of almond butter.

Tips for success:

  • Use good quality dark chocolate, at least 70% cacao. You’ll need one 3.5 ounce bar for this recipe. Smack the bar on the counter to break it into pieces.
  • If you can’t wait for the brownies to cool at room temperature, pop them in the fridge for about 20 minutes. Use a knife blade dipped in hot water to facilitate slicing.

Chocolate Hazelnut Brownies (Flourless)

This recipe makes a batch of soft, fudgy brownies infused with chocolate hazelnut butter, without flour or dairy.
Yield: 14 servings
Prep Time: 10 minutes
Cook Time: 30 minutes
Total Time: 40 minutes

Ingredients
 

  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup (224 g) chocolate-hazelnut spread
  • cup (42 g) granulated sugar
  • 1 teaspoon baking soda
  • ¼ teaspoon fine sea salt
  • 3 ½ ounces (100 g) dark chocolate, roughly chopped
  • ¼ cup (30 g) toasted hazelnuts, roughly chopped
  • ½ teaspoon flaky sea salt, such as Maldon

Instructions
 

  1. Preheat oven to 325 (160 C) degrees.
  2. Line an 8-inch square baking pan with a piece of parchment paper so that it hangs over two sides — this will make it easier to remove the brownies.
  3. Whisk the eggs in a mixing bowl with the vanilla and chocolate-hazelnut spread until smooth. Stir in the sugar, baking soda, salt and half of the chopped chocolate. Continue stirring until blended.
  4. Scrape the batter into the prepared pan, smoothing it into the corners. Sprinkle the remaining chocolate and the hazelnuts over the top. 
  5. Bake 30 minutes. Remove from the oven and sprinkle the flaky sea salt over the top.
  6. Let cool in the pan completely. Carefully lift the brownies out of the pan and cut into squares (you can chill the baked brownie in the refrigerator for 20 minutes before slicing if you find them too gooey).

Notes

  • I love Nocciolata spread for this recipe— it’s a little harder to find than the plastic supermarket tubs of Nutella, but it doesn’t include palm oil, and it’s not as sugary sweet.
