Description

Discover the secrets behind Katharine Hepburn’s legendary brownies, a timeless recipe that delivers the perfect fudgy texture. With just a few simple ingredients and no-fuss techniques, these brownies are rich, indulgent, and utterly irresistible. Whether you’re a baking novice or a seasoned pro, this recipe is a must-try for anyone who loves chocolatey, melt-in-your-mouth treats.


Ingredients

Scale
  • ½ cup (1 stick) unsalted butter
  • 2 ounces unsweetened chocolate, chopped
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ¼ cup all-purpose flour
  • ¼ teaspoon salt
  • ½ cup chopped nuts (optional, such as walnuts or pecans)

Instructions

  1. Preheat the Oven: Preheat your oven to 325°F (165°C). Grease an 8-inch square baking pan or line it with parchment paper.
  2. Melt Chocolate and Butter: In a medium saucepan, melt the butter and unsweetened chocolate over low heat, stirring until smooth. Remove from heat and let cool slightly.
  3. Mix Wet Ingredients: Stir in the sugar until well combined. Add the eggs one at a time, mixing thoroughly after each addition. Stir in the vanilla extract.
  4. Add Dry Ingredients: Gently fold in the flour and salt until just combined. Avoid overmixing. If using, stir in the chopped nuts.
  5. Bake: Pour the batter into the prepared pan and spread it evenly. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
  6. Cool and Serve: Let the brownies cool completely in the pan before cutting into squares.

Notes

  • For Extra Fudgy Brownies: Underbake slightly by checking at the 25-minute mark.
  • Storage: Store in an airtight container at room temperature for up to 3 days or freeze for longer storage.
  • Customizations: Try adding espresso powder, nut butter swirls, or a sprinkle of sea salt for creative variations.
