You know that feeling when you're scrolling through Instagram or TikTok and you see a cookie that looks so perfect it actually looks fake? That's Sarah Fennel. She’s the creative force behind Broma Bakery, and honestly, she’s spent years basically perfecting the science of the bake. But her chocolate chip cookies? They’re a whole different beast. People lose their minds over them.
It’s not just about the sugar.
Everyone has a "best" recipe. Your grandma. The back of the Toll House bag. That one fancy bakery down the street that charges six dollars for a puck of dough. But the Sarah Fennel chocolate chip cookies—specifically her "Best Chocolate Chip Cookies" version—hit a very specific nerve in the baking community because they tackle the texture problem that plagues most home bakers.
The Science of the "Broma" Texture
If you’ve ever baked a cookie that came out like a cakey disk, you know the pain. It’s disappointing. Sarah’s approach is fundamentally about moisture control and fat state. Most recipes tell you to cream room temperature butter with sugar. It's standard. It’s fine. But Sarah often leans into browned butter or very specific temperature targets to ensure that the cookie doesn't just rise—it ripples.
The ripples are the thing.
You see those concentric circles of golden-brown goodness around the edges? That’s not an accident. It’s a result of the dough spreading and setting at different intervals. When you use her specific ratio of brown sugar to granulated sugar—usually leaning heavily on the brown—you get a high moisture content that leads to that sought-after "chew."
Brown Butter is the Secret Sauce
If you aren't browning your butter, are you even making a gourmet cookie? Sarah Fennel’s recipes almost always advocate for this step. When you melt butter and cook it until the milk solids toast, you’re removing water and adding a nutty, toasted flavor profile that raw butter just can't touch.
It smells like heaven.

But there’s a catch. When you brown butter, you lose volume because the water evaporates. A lot of people mess up the Sarah Fennel chocolate chip cookies because they forget to account for that lost moisture. You have to be precise. If the recipe calls for a cup of browned butter, you usually need to start with slightly more than a cup of raw butter to hit the mark after the sizzle stops.
Why the Pan Bang Matters
We have to talk about Sarah Kieffer for a second, because the "pan-banging" technique became a viral sensation that Sarah Fennel also utilizes to great effect. The idea is simple: halfway through baking, you lift the pan and drop it against the oven rack.
Thud.
The air escapes. The cookie collapses. The edges push out. You do this every few minutes for the remainder of the bake. What you’re left with is a cookie that has a crispy, thin outer ring and a soft, molten-adjacent center. It’s a textural masterpiece. Sarah Fennel’s version of the chocolate chip cookie often incorporates this structural manipulation to ensure you don't end up with a domed, bready cookie. Nobody wants a bready chocolate chip cookie.
Salt, Chocolate, and the Quality Gap
Cheap chocolate ruins good dough. It's a hard truth.
In many of her tutorials, Sarah emphasizes using chopped chocolate bars rather than standard chips. Why? Because chips are engineered to hold their shape. They have stabilizers. They don't melt into those beautiful, shimmering pools of cocoa. When you chop a high-quality bar (think Guittard or Valrhona), you get "chocolate dust" that streaks through the dough and large chunks that create those iconic pockets of goo.
Then, there’s the salt.

A heavy hand with flaky sea salt (Maldon is the gold standard here) is non-negotiable. The salt cuts through the richness of the brown butter and the sweetness of the sugar. Without it, the cookie is just sweet. With it, the cookie is complex. It’s sophisticated.
The Chilling Requirement
Patience is the worst part of baking.
You’ve got the dough. It tastes amazing. You want to bake it now. But if you follow the Broma Bakery philosophy, you know the "rest" is where the magic happens. Chilling the dough for at least 24 hours allows the flour to fully hydrate. It also chills the fat, which means the cookies won't spread into a singular giant pancake the second they hit the heat.
The flavors also deepen. It’s like a soup or a stew—it’s better the next day. The sugars break down, the vanilla intensifies, and the result is a deeper, more toffee-like flavor.
Common Mistakes People Make with Sarah Fennel’s Recipe
Even with a perfect roadmap, things go sideways. One of the biggest issues is the "scoop and sweep" method for flour. If you’re using a measuring cup to scoop flour directly out of the bag, you’re packing it down. You’re likely using 20% more flour than the recipe intends.
Use a scale.
Sarah, like most professional bakers, provides measurements in grams. A gram is a gram. A "cup" is a lie. If you want your Sarah Fennel chocolate chip cookies to look like her photos, you have to weigh your ingredients.

Another pitfall? Oven temperature. Most home ovens are liars. They say 350°F, but they’re actually 325°F or 375°F. An oven thermometer costs ten dollars and will save your baking life. If the oven is too cold, the butter melts before the structure sets, and you get a grease puddle. Too hot, and the outside burns before the middle is even warm.
The Ingredient Breakdown
Let’s look at what’s actually inside these things. It’s not magic; it’s chemistry.
- Dark Brown Sugar: This is the MVP. It contains more molasses than light brown sugar, which leads to a softer, more acidic environment for the baking soda to react with.
- Egg Yolks: Some of Fennel’s most popular iterations call for an extra egg yolk. Why? Fat. Yolks add richness and a "fudgy" texture without the drying effect of the extra egg white.
- Vanilla Paste: While extract is fine, paste gives you those little black specks and a more concentrated punch.
- Bread Flour vs. All-Purpose: Occasionally, high-protein flour is swapped in to provide more "chew." It creates more gluten, which holds onto those air bubbles and gives the cookie some bite.
How to Get the "Look"
Google Discover loves a beautiful cookie. To get that aesthetic, you need to do the "scoop and tuck."
When you portion out your dough, don't just plop it down. Roll it into a tall cylinder rather than a perfect sphere. As it bakes, the height forces it to flow outward in a more controlled way, creating those ridges. And here’s a pro tip: as soon as the cookies come out of the oven, take a large circular cookie cutter or a glass, place it over the cookie, and "scoot" it in a circular motion.
This rounds out the edges. It makes them perfectly symmetrical. It pushes any stray bits of dough back into the center, making the cookie thicker and more professional-looking.
Actionable Steps for Your Next Batch
If you’re ready to tackle the Sarah Fennel chocolate chip cookies, don’t just wing it. Baking is a game of inches.
- Buy a Kitchen Scale: Seriously. Stop measuring by volume.
- Brown the Butter the Night Before: Let it solidify back to a soft paste. This gives you the flavor of browned butter with the structural integrity of softened butter.
- Invest in Good Chocolate: Skip the bag of semi-sweet chips. Get two bars of 60% or 70% dark chocolate and chop them by hand.
- The 24-Hour Rule: Make the dough on Friday. Bake it on Saturday. The difference in flavor is massive.
- Salt it Late: Don’t just put salt in the dough. Hit the tops with flaky salt the second they come out of the oven so the crystals stick to the melting chocolate.
The reality is that Sarah Fennel’s recipes work because they don't skip steps. They respect the ingredients. They understand that a cookie isn't just a snack; it's a balance of fat, sugar, and flour that requires a little bit of patience and a lot of high-quality chocolate. Follow the grams, watch the oven, and bang that pan. You’ll never go back to the box mix again.
