Fudgy vs Cakey Brownies: Cocoa or Chocolate, Pan Size and How to Tell When They Are Done

Fudgy brownies have a higher ratio of fat (butter and chocolate) to flour, usually no chemical leavener, and are baked until a toothpick shows moist crumbs rather than coming out clean. Cakey brownies have more flour, often a little baking powder and milk, and are baked until set like a cake. The standard fudgy recipe below bakes in an 8 x 8-inch pan at 350°F (180°C) for about 20–25 minutes.

Weights follow King Arthur Baking’s ingredient weight chart: 120 g per cup of flour, 42 g per half cup of cocoa and 113 g per stick of butter.

Fudgy cocoa brownies (8 x 8-inch pan, 16 squares)

Ingredients

• 1/2 cup (1 stick, 113 g) unsalted butter
• 1 cup (198 g) granulated sugar
• 1/2 cup (42 g) unsweetened cocoa powder, natural or Dutch-process
• 1/4 teaspoon table salt
• 2 large eggs, cold or at room temperature
• 1 teaspoon vanilla extract
• 1/2 cup (60 g) all-purpose flour
• Optional: 1/2 cup (85 g) chocolate chips or 1/2 cup (57 g) chopped walnuts

Method

1. Heat the oven to 350°F (180°C; 160°C fan; gas mark 4). Line an 8 x 8-inch metal pan with parchment, leaving an overhang to lift the brownies out.
2. Melt the butter in a saucepan over low heat or in the microwave. Off the heat, whisk in the sugar, cocoa and salt. The mixture will be grainy and warm, not hot.
3. Whisk in the eggs one at a time, then the vanilla, and whisk vigorously for about 1 minute until the batter is glossy and thick. This step helps create the shiny, crackly top.
4. Fold in the flour until no dry streaks remain, then the chips or nuts.
5. Spread evenly in the pan and bake 20–25 minutes. Start checking at 18 minutes.
6. They are done when the edges look set and slightly pulling from the pan, the center no longer looks wet and jiggly, and a toothpick inserted 1 inch from the edge comes out with moist crumbs but no raw batter.
7. Cool completely in the pan on a rack, at least 1 hour, before cutting. Fudgy brownies finish setting as they cool; cutting them warm makes them gooey and ragged.

What makes brownies fudgy, chewy or cakey

King Arthur Baking describes fudgy brownies as having a higher fat-to-flour ratio and typically no leavener, and notes that adding flour to a fudgy recipe makes it cakier. To turn the recipe above cakey, increase the flour to 3/4 cup plus 2 tablespoons (105 g), add 1/2 teaspoon baking powder and 1/4 cup (57 g) milk, and bake until a toothpick comes out clean.

Cocoa or melted chocolate?

• Cocoa powder is concentrated chocolate solids with most of the cocoa butter removed. It gives intense flavor and lets butter supply the fat, which makes the recipe simple and predictable.
• Melted unsweetened or bittersweet chocolate contributes cocoa butter, which sets firm at room temperature. That gives a denser, more truffle-like bite. Bars with sugar change the sugar balance, so use a recipe written for chocolate rather than swapping by eye.
• Both is common in rich brownies: cocoa for depth and chocolate for texture.

Because these brownies have no baking soda, natural and Dutch-process cocoa are interchangeable here. Dutch-process gives a darker, smoother flavor; natural gives a sharper one. Cocoa matters more for leavened bakes; see double chocolate muffins for an example.

Pan size conversions

Brownie thickness, and therefore bake time, depends on pan area. Use the table to scale.

Glass pans heat more slowly and hold heat longer; lower the oven to 325°F (165°C) and expect a few extra minutes. Dark metal browns edges faster. More pan math is in cake pan size conversions.

Doneness: the hardest part

Brownies keep cooking from residual heat after they leave the oven, so fudgy ones should come out when they still look slightly underdone in the very center. A toothpick can mislead: the crackly top can wipe it clean, while a melted chocolate chip can look like raw batter. Test in a few spots away from chips, about 1 inch in from the edge. An instant-read thermometer helps; King Arthur’s chewy brownie recipe, for example, gives about 220°F in the center for fully baked brownies that slice cleanly once cool.

Storing

Store cooled brownies covered at room temperature, ideally uncut or in large pieces, which stay moist longer. Brownies with cream cheese swirls or perishable toppings need the refrigerator. Brownies freeze well wrapped tightly; thaw at room temperature.

Food safety and allergens

Do not lick the bowl or eat raw brownie batter: it contains raw flour and raw eggs, which the FDA says can carry harmful bacteria until baked. This recipe contains wheat (gluten), eggs and milk, and possibly tree nuts and soy (in chocolate). Allergy-friendly versions need certified ingredients and care with cross-contact; follow your doctor’s or dietitian’s advice.

Bottom line

For fudgy brownies, keep the flour low and the fat high, skip the leavener, whisk the batter until glossy and pull the pan when a toothpick shows moist crumbs. For cakey brownies, add flour, baking powder and a little milk and bake until clean.

FAQ

Why didn’t my brownies get a shiny top?

The crackly top forms when sugar dissolves into warm butter and eggs are whisked in well. Use warm melted butter and whisk vigorously after adding the eggs.

Why are my brownies greasy?

Butter too hot when the eggs went in, or an underbaked pan. Let the butter cool slightly and bake until the center is set.

How do I cut clean squares?

Cool completely, or chill briefly, then cut with a long sharp knife wiped clean between cuts.

Can I double the recipe?

Yes. Bake it in a 9 x 13-inch pan and start checking a few minutes earlier than the longest time listed.
