Sweet Loren’s: Loren Castle. How A Recipe Makeover Built a National Cookie Brand
How I Built This with Guy Raz
October 19, 2026
Loren Castle started baking cookies after surviving cancer in her early twenties. Five years later, Sweet Loren’s refrigerated cookie dough was generating just $350,000 a year. But instead of giving up, she listened to customers, and reinvented the dough without gluten, dairy, eggs or nuts.

Our presenting sponsor today is Anthropic, the team behind Claude. Every founder on this show started with a hard question. Not the marketing plan, the 2 AM kind. Is this idea any good? Am I the one to build it? Should I quit my job? Anthropic got built the same way. A public benefit corporation founded on one hard question. How do we make sure AI goes well for people?
So, they asked over 100,000 people, their hopes and their fears, and are publishing what they find, even the uncomfortable parts. Me?
I've got my own hard question about AI. Here it is. If everyone has access to something that can help them write the business plan, build the prototype, analyze the market, maybe even come up with the idea, what separates the people who actually build something from everyone else?
I don't have a clean answer yet, so I've been sitting with it, with Claude. There's hope in hard questions. Ask yours at claude.ai/h i b t. We get support from US Bank. A question I love asking founders. What's the one decision you almost didn't make, the one that changed everything? Because it's never the obvious stuff. It's never, I decided to start a company. It's the small, boring, Tuesday afternoon decision you barely remember making until you realize it's the reason everything after it either worked or didn't. Say you're 18 months in. Business is growing. You've got expenses coming from Six Directions, gas for the van, office supplies, your phone bill, team lunches that are actually client meetings. And you're putting it all on whatever card you grabbed in year one. You're not thinking about it. Why would you? You've got bigger problems. But here's the thing. Path A, you keep going like that. End of the year, you're sorting through statements, trying to figure out what went where. You've left hundreds, maybe thousands on the table and rewards you never earned. Money that could have gone back into the business. Path B, you pause and get the US. Bank Triple Cash Rewards Visa Business Card. Now, you're earning 3% cash back on gas and EV charging, office supply stores, cell phone service and restaurants. You pick up an extra $750 cash back as a bonus. And you've got a low APR in purchases and balance transfers for 12 months while you're scaling.
Same business, same expenses, two completely different outcomes based on one small decision.

I'm talking every day in my apartment. I would just test different types of potato starch and tapioca starch, you know, in different proportions of it. So honestly, it was just so much playing around. I tried to hire food scientists to help me because I thought like that would be the easy solve.
And the food always tasted like a science project.

Welcome to How I Built This, a show about innovators, entrepreneurs, idealists, and the stories behind the movements they built.
I'm Guy Raz and on the show today, how Loren Castle made cookie dough taste good, even without gluten, dairy, and eggs, and then grew that into Sweet Loren's, a brand that sold in more than 30,000 stores.
A lot of founders think that to build a great brand, you've got to come up with a totally original idea. But the fact is, a lot of really great products and brands built around them are simply more creative versions of what's already out there in the market. For example, Graza Olive Oil. The founders realized most people have no idea how to choose olive oil. So they made it simple. Three oils for three different uses. Two for cooking and one for drizzling on salad or tomatoes. They packaged it up in a fun, squeezy bottle, and it's become a national brand in less than four years. In fact, we really should do an episode on it. Anyway, today's story is precisely about taking on a category that wasn't very innovative. Refrigerated cookie dough. And for most of the past few decades, it was dominated and probably still is by tubes of Nestle Toll House. So when Loren Castle decided to start selling her own brand of refrigerated cookie dough, she saw an opportunity not only to offer up an alternative to the usual brands, but eventually to make it gluten, allergen, and dairy-free and vegan. Which sounds like a buzzkill for a cookie. I mean, you kind of want all those things in a cookie, right? But what if you could take all of those things out, the gluten, the dairy, the allergens, and actually make the cookie dough taste good? That was how, over many, many years, Loren was able to grow Sweet Loren into a national brand that's now sold in more than 30,000 stores across the country. And the thing is, Loren used to sell cookie dough that wasn't gluten and allergen free. But when she launched it as an option, it quickly outsold all her other cookies. So she pivoted and turned Sweet Loren's into a brand entirely aligned with consumers looking for an allergen-free cookie that didn't taste like cardboard.
