Hazelnut Brownies

You’ve had Nutella, right? Was your life ever the same afterward? No, it was not. Because you’ve probably put that delicious chocolate hazelnut spread on everything from pretzels to graham crackers to toast. And why wouldn’t you? It’s delicious. I miss it very much in migraine life.

While these aren’t Nutella brownies, they are a wonderful combination of chocolate and hazelnut. I adapted King Arthur Flour’s “On the Fence” brownie recipe, which yields a somewhat cakey, somewhat fudgy treat, by adding a tablespoon of hazelnut liqueur and some chopped toasted hazelnuts to the batter, then topping the baked treats with a hazelnut buttercream and more toasted hazelnuts.


For the brownies

  • 1 cup butter
  • 2 1/4 cups sugar
  • 1 1/4 cups Dutch process cocoa
  • 1 teaspoon salt
  • 1 teaspoon baking powder
  • 1/2 tablespoon vanilla extract
  • 1 tablespoon hazelnut liqueur
  • 4 eggs
  • 1 1/2 cups flour
  • 1 cup chopped toasted hazelnuts

For the frosting

  • 12 tablespoons butter, at room temperature
  • 2 1/2 cups powdered sugar
  • 1/2 tablespoon vanilla extract
  • 2 tablespoons hazelnut liqueur
  • Chopped toasted hazelnuts


Preheat oven to 350 degrees. Lightly grease a 9 x 13 baking tin.

In a large microwave-save bowl, melt butter. Stir in sugar and microwave for another 45-60 seconds, until the mixture is just hot. Stir in cocoa powder, salt, and baking powder, then whisk in eggs, vanilla extract, and hazelnut liqueur. Stir in flour, then chopped hazelnuts. Spread evenly in prepared pan.

Bake for 28-30 minutes, until a cake tester inserted in the center comes out clean. Cool completely before frosting.

To make the frosting, beat butter on medium speed for 1-2 minutes. Add powdered sugar and allow the mixture to incorporate fully; this will take a few minutes. Add vanilla extract and hazelnut liqueur and beat until combined.

Frost brownies and sprinkle with chopped toasted hazelnuts. Cut into two-inch squares; store in an airtight container at room temperature for 2-3 days.
