Why you’ll love this recipe

These brownies get their deep chocolate flavor from cocoa powder, so there is no chocolate to chop or temper. The result is dense and fudgy, with the paper-thin crackly top people look for in a bakery brownie.

  • One bowl and pantry ingredients.
  • No mixer — a spoon and a little elbow grease.
  • Freezes well for game day or lunchboxes.

The secret to the crackly top

The shiny, crackly crust forms when sugar dissolves in hot butter and eggs, then sets into a thin meringue-like layer on top as the brownies bake. Heating the butter, sugar and cocoa together starts dissolving the sugar, and cold eggs plus a vigorous final beating help build that glossy batter. Baking at a moderate 325°F (165°C) lets the center turn fudgy without the edges drying out. Resist cutting them warm: the center is still soft and settles into its dense, fudgy texture only as it cools completely.

Instructions

  1. Step 1: Prep the pan

    Heat the oven to 325°F (165°C) with a rack in the lower third. Line an 8-inch square metal pan with parchment or foil, leaving an overhang on two sides.

  2. Step 2: Melt butter, sugar and cocoa

    Combine the butter, sugar, cocoa and salt in a heatproof bowl set over a saucepan of barely simmering water. Stir until the butter melts and the mixture is hot to the touch and fairly smooth, about 5 minutes. It will look gritty; that is normal.

  3. Step 3: Add vanilla and eggs

    Remove the bowl from the heat and let it cool until warm, not hot. Stir in the vanilla, then the eggs one at a time, stirring vigorously after each until the batter is thick, shiny and well blended.

  4. Step 4: Add the flour

    Stir in the flour until no streaks remain, then beat vigorously with a wooden spoon or spatula for 40 strokes. Fold in the chips or nuts if using.

    Tip: That brisk final beating is what gives the batter its glossy look and helps form the thin, crackly top.

  5. Step 5: Bake

    Spread the batter evenly in the pan. Bake 20–25 minutes, until a toothpick inserted in the center comes out with moist crumbs but not wet batter.

  6. Step 6: Cool completely and cut

    Cool the brownies completely in the pan on a rack, about 1½ hours. Lift them out with the overhang and cut into 16 squares.

    Tip: For the cleanest edges, chill the cooled slab 30 minutes and cut with a long knife wiped clean between cuts.

Equipment

Tips for the best results

  • Use a metal pan. Glass heats more slowly and can leave the edges overbaked before the center is done.
  • Pull the brownies when a toothpick shows moist crumbs. They keep setting as they cool, and overbaking turns fudgy into cakey.
  • Weigh the flour if you can (60 g). With so little flour, a heavy cup makes a noticeable difference.

Storage, reheating and freezing

Refrigerator
Store airtight at room temperature for up to 3 days or in the fridge for up to 1 week. Chilled brownies are extra dense and fudgy.
Reheating
Warm a brownie in the microwave for 10–15 seconds.
Freezing
Wrap individual brownies or the uncut slab tightly and freeze up to 3 months. Thaw at room temperature.

Frequently asked questions

What makes brownies fudgy instead of cakey?

A high ratio of fat and sugar to flour, no chemical leavening and slight underbaking. This recipe uses only ½ cup flour and no baking powder.

Can I double the recipe?

Yes. Use a 9×13-inch metal pan and start checking at 25 minutes.

Why didn't my brownies get a crackly top?

The sugar was not dissolved enough in the hot butter or the batter was not beaten vigorously at the end. Make sure the butter mixture is hot and give it the full 40 strokes.
