Ingredients

Scale
  • 1 cup (227g) unsalted butter
  • 1 1/4 cups (250g) granulated sugar
  • 1/4 cup (50g) brown sugar
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • 3/4 cup (95g) all-purpose flour
  • 1/2 cup (50g) unsweetened cocoa powder
  • 1 tbsp espresso powder
  • 1/2 tsp salt
  • Flaky sea salt, for sprinkling on top
  • Optional: 1/2 cup chopped walnuts or chocolate chips

Instructions

  1. Brown the butter in a medium saucepan over medium heat for 5-7 minutes, whisking gently until it turns golden-brown and smells nutty. Remove from heat and let cool slightly.
  2. In a large bowl, whisk together granulated sugar and brown sugar. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract until smooth and glossy.
  3. Slowly pour the slightly cooled brown butter into the sugar-egg mixture, whisking continuously to combine.
  4. In a separate bowl, sift together flour, cocoa powder, espresso powder, and salt.
  5. Gently fold the dry ingredients into the wet mixture using a spatula until no flour streaks remain. Do not overmix.
  6. Line an 8×8 inch baking pan with parchment paper, leaving an overhang for easy removal. Pour the batter in and smooth the top.
  7. Bake at 350°F (175°C) for 25-30 minutes. Check at 25 minutes; edges should be set and center slightly soft with moist crumbs on a toothpick.
  8. Immediately after baking, sprinkle flaky sea salt evenly over the surface.
  9. Let brownies cool completely in the pan on a cooling rack for at least 1 hour.
  10. Use the parchment overhang to lift brownies out of the pan, slice into squares, and serve.

Notes

Use a light-colored pan to brown butter to better monitor color changes. Do not overmix batter to avoid tough brownies. Sprinkle flaky sea salt immediately after baking for best adherence and flavor contrast. Let brownies cool completely for fudgy texture and clean cuts. Optional add-ins include chopped nuts or chocolate chips. For gluten-free, substitute flour with a 1:1 gluten-free baking blend containing xanthan gum. For dairy-free, use vegan butter or coconut oil and flax eggs.
