If you’ve spent any time on the food side of Instagram or TikTok lately, you’ve probably seen a slab of brownies so fudgy they look illegal. That’s the Sarah Fennel effect. The woman behind the massive digital brand Broma Bakery didn't just wake up one day with a bestselling cookbook titled Sweet Tooth; she spent over a decade grinding in a niche that many people thought was oversaturated.
She's real.
Most "influencer" cookbooks feel like a collection of ghostwritten recipes and stock photos, but Sweet Tooth by Sarah Fennel hit the New York Times Best Sellers list because it actually solves the problems home bakers face. You know the ones. Your cookies spread too thin. Your cake is dry. Your frosting tastes like straight sticks of butter. Sarah basically took the intimidation factor of professional pastry and dragged it down to earth, using a conversational tone that feels more like a text from a friend than a lecture from a chef.
The Long Road to Sweet Tooth and Sarah Fennel’s Rise
Let’s be honest: the "overnight success" narrative is almost always a lie. Sarah started Broma Bakery way back in 2010. She was a college student at the University of Michigan, feeling a bit lost, and used a blog as a creative outlet. Back then, food blogging wasn't a career path. It was a hobby for people who liked taking blurry photos of their lunch.
She didn't have a culinary degree.
That’s actually her secret weapon. Because she taught herself how to bake, she understands why a recipe fails for a normal person. She spent years testing the science of fats, sugars, and flours in a standard home kitchen, not a commercial lab. When she talks about the importance of room-temperature eggs, it’s not because a textbook told her to; it’s because she ruined a dozen batches of buttercream finding out the hard way.
By the time the Sweet Tooth cookbook was announced, she had already built a massive community. People didn't just want recipes; they wanted her specific aesthetic—moody lighting, messy-but-perfect drips of chocolate, and a genuine obsession with high-quality vanilla.
Why the Sweet Tooth Recipes Actually Work
There is a specific science to why people are obsessed with Sarah's recipes. Most baking books focus on "perfection." Sarah focuses on "indulgence."

Take her famous "Best Brownies in the World." If you look at the analytics of what people search for regarding Sweet Tooth Sarah Fennel, it’s almost always those brownies. Why? Because she cracks the code on the crinkly top. It’s not magic. It’s about dissolving the sugar into the butter and eggs properly to create that meringue-like crust.
What makes her approach different:
- She prioritizes texture over everything.
- The recipes use "accessible luxury" ingredients—stuff you find at a normal grocery store but used in higher ratios.
- Her instructions are written for people who get distracted.
- She focuses heavily on the "why" so you can troubleshoot in real-time.
Honestly, it’s refreshing. We’ve all tried those Pinterest recipes that look like a million bucks but taste like cardboard. Sarah’s stuff is the opposite. It’s messy, it’s heavy on the salt to balance the sugar, and it’s designed to be shared.
The Business of Broma: More Than Just Sugar
It is a massive mistake to look at Sarah Fennel and just see a baker. She is a powerhouse of a businesswoman. Beyond the Sweet Tooth book, she founded Foodtography School.
Think about that for a second.
She realized that thousands of people wanted to do what she did, but they didn't know how to make food look appetizing on a smartphone screen. She monetized her skill set by teaching the technical side of photography—composition, lighting, and editing. She turned a food blog into an educational tech company.
This is likely why her cookbook launch was so successful. She understands the "visual hunger" of the modern consumer. We eat with our eyes first, and Sarah is a master of the visual hook. Whether it's a 15-second reel of a caramel drizzle or a high-res photo of a lemon loaf, she knows how to stop the scroll.
Dealing With the "Health" Critique
In an era of keto, paleo, and sugar-free everything, a book literally named Sweet Tooth is a bold move. Sarah has been vocal about her philosophy: eat the real thing.

She isn't interested in "healthy swaps" that leave you unsatisfied. If you want a cookie, eat a damn cookie. Just make sure it’s the best cookie you’ve ever had. This leans into the "Intuitive Eating" movement that has gained massive traction over the last few years. By removing the guilt from dessert, she’s actually built a deeper level of trust with her audience.
There’s no "skinny" version of her recipes. There is just the delicious version.
Technical Mastery Without the Ego
One thing you'll notice in Sweet Tooth is the lack of "chef-speak." You won't find overly complicated French terms just for the sake of sounding fancy. Instead, she’ll describe a texture as "pillowy" or "cloud-like."
But don't let the casual language fool you. The ratios are precise. Baking is chemistry, and Sarah treats it as such. She’s documented her testing process extensively—sometimes making 20 versions of a single cake to ensure the crumb is exactly right.
Surprising Facts About the Book's Development:
- She shot almost all the photography herself, which is rare for major-label cookbooks.
- The book includes "Small Batch" sections, acknowledging that not everyone wants 24 cupcakes sitting on their counter.
- It took years to finalize because she refused to include "filler" recipes.
How to Get the Most Out of Sarah Fennel’s Recipes
If you’ve just picked up a copy of the book or you’re browsing Broma Bakery for the first time, don’t just jump into the most complex layer cake.
Start with the basics.
Her chocolate chip cookie recipe is a masterclass in browning butter. If you’ve never browned butter before, it’ll change your life. It adds a nutty, toasted depth that makes a standard cookie taste like it came from a high-end bistro.

Also, buy a kitchen scale. Sarah is a huge advocate for weighing ingredients in grams. A "cup" of flour can vary by 20-30% depending on how tightly you pack it. If you want your bake to look like hers, you have to measure like she does.
The Future of the Brand
Where does she go from here? With Sweet Tooth cementing her status as a titan in the lifestyle and cooking space, the brand is likely to expand into kitchenware or perhaps more television appearances. She’s already a staple on morning shows, but her real strength remains her direct connection to her followers.
She responds to comments. She shares her failures. She shows the "behind the scenes" of a messy kitchen that hasn't been cleaned in three days.
That authenticity is why Sarah Fennel isn't just another food blogger. She’s a brand that people actually trust. In a world of AI-generated recipes and fake "perfection," her obsession with real butter and real sugar feels like a relief.
Actionable Steps for Aspiring Bakers
To truly master the Sweet Tooth style of baking, you need to change your mindset. It’s not about following a set of instructions; it’s about understanding the ingredients.
- Invest in a Digital Scale: Stop using measuring cups for flour. It’s the number one reason bakes fail. Weighing your ingredients ensures consistency every single time.
- Temperature Matters: If a recipe says "room temperature," it’s not a suggestion. Cold eggs will break an emulsion. Cold butter won't cream properly with sugar. Give yourself an hour of prep time to let everything sit out.
- Don't Fear Salt: Sarah uses more salt in her desserts than most. This isn't to make them salty; it’s to amplify the cocoa and vanilla notes. Use high-quality flaky sea salt for finishing.
- Watch the Visuals: Before you bake a specific recipe from the book, check Sarah’s social media for a video of that same item. Seeing the "vibe" of the batter or the dough helps you know if you're on the right track.
- Start with the Brownies: If you want an immediate win, the brownie recipe is foolproof and provides that instant gratification that keeps you motivated to try harder recipes.
Baking is supposed to be fun, not a chore. Sarah Fennel’s entire career is proof that if you focus on the joy of the process (and a lot of high-quality chocolate), the results will follow. Every kitchen has a few "fail" stories, but with the right guidance, those become the lessons that lead to your own "best ever" moment.
