Ultimate Fudgy Brownies (Crinkly Top, Fudgy Center)
Equipment
- 9×13-inch baking pan
- Parchment paper
- Large Mixing Bowl
- Whisk
- Spatula
- Sifter For cocoa and flour
Ingredients
- 1 cup unsalted butter melted
- 2 cups granulated sugar
- 4 large eggs
- 1 tsp vanilla extract
- ¾ cup unsweetened cocoa powder
- 1 cup all-purpose flour
- ½ tsp salt
- 1 cup chocolate chips optional
Instructions
- Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
- Mix wet ingredients: In a large bowl, whisk melted butter and sugar until well combined. Add eggs one at a time, whisking well after each addition. Stir in vanilla.

- Serve: Cut into 16 squares and enjoy.

For the science behind the crinkly top, King Arthur Baking explains how dissolving sugar in eggs creates that signature glossy crust.
Instructions
- Preheat oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper.
- Mix wet ingredients: In a large bowl, whisk melted butter and sugar until combined. Add eggs one at a time, whisking well after each. Stir in vanilla.
- Add dry ingredients: Sift in cocoa powder, flour, and salt. Fold gently until just combined – do not overmix.
- Add chocolate chips: Fold in chocolate chips if using.
- Bake: Pour batter into prepared pan. Bake for 25-30 minutes. A toothpick inserted should come out with moist crumbs, not wet batter.

- Slice: Use a hot knife for clean cuts (dip in hot water, wipe clean between slices).
For the best texture, Serious Eats recommends resting the batter for 20 minutes before baking to enhance the shiny crust.
