Equipment

  • 1 9x13 inch baking pan greased
  • 1 Mixing Bowl large
  • 1 Whisk
  • 1 Spatula

Ingredients
  

Dry Ingredients

  • 1 cup all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1/2 teaspoon salt

Wet Ingredients

  • 1 cup unsalted butter melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract

Mix-ins

  • 1 cup chopped hazelnuts
  • 1/2 cup chocolate chips optional

Instructions
 

Preparation

  • Preheat your oven to 350°F. Grease a 9x13 inch baking pan with butter or non-stick spray, and set aside.
  • In a large mixing bowl, whisk together the melted butter and granulated sugar until well combined. Add the eggs one at a time, whisking thoroughly after each addition. Stir in the vanilla extract.
  • In a separate bowl, sift together the flour, cocoa powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
  • Gently fold in the chopped hazelnuts and chocolate chips if using, ensuring they are evenly distributed throughout the batter.

Baking

  • Pour the brownie batter into the prepared baking pan. Use a spatula to spread the batter evenly. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with only a few crumbs attached.
  • Allow the brownies to cool in the pan for 10 minutes before transferring them to a wire rack to cool completely.

Serving

  • Once cooled, cut the brownies into squares and serve on their own or with a scoop of vanilla ice cream for an indulgent dessert.

Storage

  • Store leftover brownies in an airtight container at room temperature for up to 4 days. For longer storage, wrap them tightly and freeze for up to 3 months.
