Ingredients

  • 3/4 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup unsweetened Dutch-processed cocoa powder
  • 3/4 cup (12 tablespoons) unsalted butter
  • 2 tablespoons vegetable oil
  • 1 1/2 cups sugar (divided)
  • 1 teaspoon pure vanilla extract
  • 2 large eggs plus 1 egg yolk
  • 2/3 cup semi-sweet chocolate chips
  • 1/2 to 1 cup add-ins (e.g., M&M's, nuts, or roughly chopped cookies)

Instructions

  • Preheat oven to 350°F (175°C). Line an 8x8 or 9x9 inch baking pan with parchment paper and lightly spray with non-stick baking spray.
  • Sift flour, salt, and cocoa powder into a bowl. Set aside.
  • In a saucepan over medium heat, combine butter, oil, and 1/2 cup sugar. Stir until melted and sugar dissolves. Remove from heat.
  • In a separate bowl, whisk 2 eggs, 1 egg yolk, and remaining 1 cup sugar until smooth. Add vanilla extract.
  • Slowly add warm butter-oil-sugar mixture to egg mixture, whisking constantly.
  • Add dry ingredients and fold until just combined, avoiding overmixing.
  • Fold in chocolate chips and 1/2 to 1 cup of add-ins.
  • Pour batter into prepared pan and smooth the top.
  • Bake 30 minutes (9-inch) or 40 minutes (8-inch) until edges firm and top looks crackly but center is still glossy.
  • Remove from oven and cool completely in pan before cutting.

Notes

Cool brownies completely (at least 1 hour) for clean slices. Store in an airtight container at room temperature up to 2 days. Adjust add-ins based on preference (e.g., toffee bits, dried fruit, or candy pieces).
