  • ¼ cup unsalted butter
  • ¼ cup canola oil
  • 4 oz. semisweet chocolate chopped
  • ½ cup brown sugar lightly packed
  • ½ cup granulated sugar
  • 2 large eggs at room temperature
  • 2 tsp. vanilla extract
  • cup + 2 TBSP flour
  • cup cocoa powder
  • ½ tsp. salt
  • 1 tsp. espresso powder
  • 3 oz. dark chocolate chunks


  • Preheat oven to 350 degrees. Line a 9x9 baking pan with parchment paper, spray with baking spray and set aside.
  • In a large glass mixing bowl combine the butter, oil, and chopped chocolate. Microwave in 30 second bursts, stirring after each round, until chocolate is fully melted and smooth (about 1 minute).
  • Whisk in sugars until smooth, thick, and glossy, about 2 minutes. Whisk in the eggs and vanilla until thick, about 1 minute more. Sift the flour, cocoa powder, salt, and espresso powder into bowl, then scatter 2 ounces of the dark chocolate chunks over top. Gently fold dry ingredients into batter, being sure to leave no streaks of flour behind.
  • Pour batter into prepared pan, top with remaining chocolate chunks, and bake in preheated oven for 18 - 20 minutes, or until a toothpick inserted into the center of the pan comes out with just a few crumbs on it.
  • Cool brownies completely to room temperature before slicing and serving.
