Easy One-Bowl Brownies

This easy brownie recipe is everything a brownie should be - chewy, dense, melt-in-your mouth chocolatey. One bowl, one sheet of foil, one pan, done.
Yield: 24 brownies

Ingredients

  • 4 ounces unsweetened chocolate I like the Ghiradelli 60% or 100% cacao unsweetened chocolate bars; broken into smaller pieces
  • 3/4 cup unsalted butter 1.5 sticks
  • 1 3/4 cups sugar 400 g
  • 3 eggs
  • 1 teaspoon pure vanilla extract
  • 1 cup all-purpose flour 130 g
  • 1 teaspoon fine-grain sea salt

Optional add-ins

  • 1 cup chopped pecans optional; raw or toasted are both good
  • 1 cup chocolate chips I use semisweet

Instructions

  • Preheat oven to 350 degrees Fahrenheit (175° C).
  • Line a 9x13 pan with piece of foil long enough to extend over the ends of the pan, and grease the foil and the rest of the pan. I have also used parchment paper which is great for its non-stick properties.
  • In a large microwaveable bowl, add the butter and the chocolate (break the chocolate into pieces).
  • Microwave for about a minute at half power, removing and stirring to judge how much the chocolate has melted, then continue in 15 second increments after that. It usually takes me about a minute and a half to completely melt the chocolate.
  • Stir in the sugar. Give the mixture a quick poke to make sure it's room temp; if not, let it cool for a few minutes, then whisk in the eggs, vanilla, and salt.
  • Stir in the flour, and if using, the pecans and/or chocolate chips. Mix well.
  • Spread the batter into the pan.
  • Bake for 30 - 40 minutes, until shiny on top, slightly lifted away from the sides of the pan, and a toothpick inserted in the center comes out crumby, not wet.
  • Let cool for 20-30 minutes, then remove the brownies from the pan with the foil or parchment "handles."
  • Cut into squares, and enjoy!
  • Store in an air-tight container at room temp.

Notes
