Fudge brownies are dense, glossy and deeply chocolatey, and this version comes together with one bowl, a whisk and about 15 minutes of hands-on time. The recipe card below has every measurement, and the sections that follow explain each detail so you can bake them with confidence.
Fudge Brownies Ingredients and What Each One Does
Every ingredient in these fudge brownies has a clear job, and all nine are easy to find at any grocery store.
Butter and semisweet chocolate
Half a cup of unsalted butter and four ounces of chopped semisweet chocolate melt together to form the fudgy base of the batter. A chopped bar such as Ghirardelli or Guittard melts a little smoother than chips, though about two-thirds cup of chips equals four ounces.
Unsalted butter lets you control the salt level. The fat from both the butter and the chocolate is what keeps the center soft instead of cakey.
Sugar and eggs
One cup of granulated sugar sweetens the brownies and, once it dissolves into the warm chocolate, helps form the thin shiny crust on top. Two large eggs at room temperature blend in more smoothly than cold ones.
The eggs also give the brownies just enough structure to hold a clean square. Without them the batter would bake into a puddle of chocolate.
Flour, cocoa powder and salt
Only half a cup of all-purpose flour goes into the batter, which is the main reason these fudge brownies stay dense rather than cakey. A quarter cup of unsweetened cocoa powder deepens the chocolate flavor, and Dutch-process cocoa such as Droste gives a darker color while natural cocoa tastes slightly brighter.
A quarter teaspoon of fine sea salt sharpens the chocolate. A teaspoon of pure vanilla extract rounds everything out.
Chocolate chips
Half a cup of semisweet chocolate chips folded in at the end stay soft and slightly molten in the center of each square. They also add little pockets of texture, so every bite has something to hold onto.
How to Make Fudge Brownies Step by Step
Making fudge brownies takes one heatproof bowl, a whisk, an 8 inch square pan and about 15 minutes of hands-on work before the oven does the rest.
Prepare the pan
Heat the oven to 350°F and line an 8 inch square pan with parchment paper, leaving an overhang on two sides. Lightly grease the parchment so the edges release cleanly.
The overhang becomes a pair of handles for lifting the whole slab out later. That makes cutting far easier than trying to pry squares out of the pan.
Melt the butter and chocolate
Place the butter and chopped chocolate in a heatproof bowl set over a saucepan of barely simmering water, without letting the bowl touch the water. Stir until smooth, which takes about 3 minutes.
You can also melt them in the microwave in 20 second bursts, stirring after each one. Let the melted mixture cool for 5 minutes so it is warm rather than hot, because hot chocolate can scramble the eggs.
Whisk in the sugar and eggs
Whisk the sugar into the cooled chocolate mixture until it looks slightly grainy, then whisk in the eggs one at a time. Add the vanilla and keep whisking for about 1 minute, until the batter turns thick and glossy.
That minute of whisking is what builds the shiny, crackly top. Skip it and the surface bakes up dull.
Fold in the dry ingredients
Sift or sprinkle the flour, cocoa powder and salt over the batter, then fold with a spatula until no dry streaks remain. Stop mixing as soon as the streaks disappear, because overmixing builds gluten and makes the brownies tougher.
Fold in the chocolate chips, then scrape the batter into the pan. Spread it into an even layer all the way into the corners.
Bake until the edges are set
Bake for 28 to 32 minutes, until the edges look set and a toothpick inserted in the center comes out with moist crumbs rather than wet batter. The center should still look slightly soft, because it keeps cooking in the hot pan as it cools.
Cool before cutting
Let the brownies cool in the pan for at least 1 hour, then lift them out using the parchment and cut them into 16 squares. For the cleanest edges, chill the slab for 30 minutes first and wipe the knife clean between cuts.
Tips for the Fudgiest Fudge Brownies
A few small habits separate truly fudgy brownies from ones that taste like chocolate cake.
Do not overbake
Pull the pan from the oven while the center still looks a touch underdone. Ovens vary, so start checking at 28 minutes and trust the toothpick over the timer.
Measure the flour carefully
Spoon the flour into the measuring cup and level it with a knife instead of scooping straight from the bag. Scooping packs in extra flour, and even a couple of extra tablespoons pushes fudge brownies toward cake.
Swap in a different pan
A 9 inch square pan also works, but the brownies bake up thinner, so start checking at 24 minutes. Avoid a 9 by 13 inch pan unless you double the recipe, because the batter will spread too thin and dry out.
Easy variations
Swap the chocolate chips for chopped walnuts or pecans for crunch, or press a pinch of flaky sea salt on top right after the pan comes out of the oven. The recipe card leaves these out, so treat them as optional additions.
Storing and Serving Fudge Brownies
Store cooled fudge brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 7 days. For longer storage, wrap individual squares tightly and freeze them for up to 3 months.
Thaw frozen squares at room temperature for about an hour, or warm one in the microwave for 10 seconds for a just-baked texture. Fudge brownies also taste even richer the next day, so they are a great make-ahead dessert.
Serve them warm with vanilla ice cream, a spoonful of hot fudge sauce or a dusting of powdered sugar. A cold glass of milk or a mug of black coffee is the classic partner.
A Short History of Fudge Brownies
Brownies are an American invention, and the Palmer House Hotel in Chicago is often credited with serving one at the 1893 World’s Columbian Exposition. Early recipes also appeared in the Boston Cooking-School Cook Book by Fannie Farmer in the 1890s.
Those first brownies were usually closer to a bar cookie. The modern fudge brownie, with melted chocolate and a high ratio of fat and sugar to flour, grew out of home bakers chasing a denser, gooier texture.
Today fudge brownies are one of the most baked desserts in American kitchens. They need no special equipment, and they work for bake sales, potlucks and weeknight cravings alike.

Notes
Do not overbake. The center should still look slightly soft when you remove the pan. A 9 inch square pan also works, but the brownies will be thinner, so start checking at 24 minutes. Spoon and level the flour rather than scooping it. Store cooled brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 7 days. Freeze individual squares, wrapped tightly, for up to 3 months. Thaw at room temperature for about 1 hour, or microwave one square for 10 seconds.

Fudge Brownies FAQ
How do you know when fudge brownies are done?
The edges should look set and the center should still look slightly soft. A toothpick inserted in the middle should come out with moist crumbs, not wet batter, usually between 28 and 32 minutes.
Why are my brownies cakey instead of fudgy?
Cakey brownies usually come from too much flour, too much mixing or too long in the oven. Level your flour, fold only until the streaks disappear and pull the pan while the center is still slightly soft.
Can you use chocolate chips instead of a chopped chocolate bar?
Yes, about two-thirds cup of semisweet chips equals four ounces of chopped chocolate. A chopped bar melts a little smoother, but chips still make delicious fudge brownies.
How do you cut fudge brownies into clean squares?
Let the brownies cool for at least 1 hour, then chill the slab for 30 minutes. Lift it out with the parchment and wipe a sharp knife clean between cuts.
How long do fudge brownies last, and can you freeze them?
Fudge brownies keep in an airtight container for up to 3 days at room temperature or up to 7 days in the refrigerator. Wrapped tightly, they freeze well for up to 3 months.
Can you bake fudge brownies in a different size pan?
A 9 inch square pan works well, and the brownies will be a little thinner, so start checking at 24 minutes. A 9 by 13 inch pan needs a doubled batch.
Why This Fudge Brownies Recipe Works
Melting the butter and chocolate together first means the fat is already blended into the batter, so the brownies bake up dense and smooth. There is no baking powder or baking soda in the recipe, which keeps the brownies from puffing up into cake.
Half a cup of flour against a full cup of sugar is a very low ratio, and that is what gives fudge brownies their gooey center. Whisking the sugar and eggs into the warm chocolate, then continuing for a full minute, dissolves the sugar and creates the shiny, crackly top.
Using both cocoa powder and real chocolate layers the flavor. Cocoa brings the deep, slightly bitter backbone, while the semisweet chocolate and chips bring richness and melty pockets.
