The Ultimate Cookie Handbook

Ever scratch your head and wonder why a recipe didn’t turn out like the picture?

You see a fabulous cookie recipe on Pinterest. You buy all the ingredients and get to work, making a mess. You’re so excited when the timer goes off… but you end up utterly disappointed when something goes wrong. The cookies look nothing like the picture. They’re too flat, puffy, greasy, crumbly, hard, bland, or just not what they’re supposed to be. You just wasted time and ingredients on something no one wants to eat. You don’t know what went wrong and feel completely frustrated.

We’ve ALL been there.

Imagine instead if you knew exactly how to bake up perfect cookies every time. No guesswork. They look just like the picture and all your friends and family beg you to share the recipe. Imagine that you are able to recreate your Grandma’s secret recipe or the local bakery’s. Imagine that you can create your version of the ultimate cookie, the cookie of your dreams, consistently.

That would be nice, wouldn’t it? It turns out there’s an eBook that can teach you exactly that…

Here’s the scoop…

Like everyone, I’ve had many frustrating batches of failed cookies. I tried following tips I read and while some worked, others didn’t. I simply didn’t understand the science of baking and it was creating inconsistent results. I realized I needed to actually SEE the baking science in action so I could understand it. I published the results of one of my first crazy baking experiments in my Ultimate Guide to Chocolate Chip Cookies post that has been visited by over half a million people since! You can think of The Ultimate Cookie Handbook as my Ultimate Guide blog series on steroids!

As a professional chef and published cookbook author, I know TOO MUCH about cookies and am desperate to share!

I’ve done the hard work for you. I’ve created a detailed and handy valuable resource so you can see how cookie science works alongside actionable tips, tricks, and secrets to answer ALL your cookie baking problems. You can even use this guide to write your own perfect recipes! No more failed cookies. Just FUN in the kitchen.

by George in Quito on The Ultimate Cookie Handbook

I've been following Tessa for a couple of years now, so when she published her book, I got it right away. Tessa does not disappoint! All her directions are simple and to the point. She reminds me a little of Rose Levy Beranbaum as she explains why something happens. Her recipes are a thoroughly enjoyable read, and make baking something to look forward to. You owe it to yourself to get her book.

by Stephanie Prassos on The Ultimate Cookie Handbook

I'm so glad I bought this e-book. It is so straightforward, concise (as can be) yet thorough. I love how Tessa goes through scientific reasoning of ingredients and baking. The layout is perfect and I love the section on how to achieve the type of cookie you like. I love baking chocolate chip cookies and I am looking forward to trying out all her tips and tricks. At first I wasn't too happy it was an ebook (I like hardcopies) but I am printing and binding it to add to all my cookbooks. What a steal.

by Katja on The Ultimate Cookie Handbook

Incredible that someone takes the effort to try out all the combinations how different ingredients and ways of treating the dough will give you a different result.

In this way you really can find your own favorite cookie. Tessa explains very well how small things can change your cookie. So, you also learn about possible mistakes you made.

Also I like that it's an e-book! You've it always with you and it's better for the environment.

The layout and the photos are nice and clear, it's a pleasure to bake with this Handbook!

by Janice Howard on The Ultimate Cookie Handbook

OMG I owe Tessa and her Ultimate Cookie Handbook a thousand thanks for making me the resident Cookie Expert at work! I was pretty OK at making cookies before but now they are all AWESOME and I'm becoming known for my cookies wherever I go. It makes a big difference understanding how the different ingredients work so I can tell even before making recipes now how they're going to come out. Cookies, check! It's really fun to be able to make something that so many people enjoy

by Toni T. on The Ultimate Cookie Handbook

Chocolate Chip Cookies have been my favorite cookie since childhood. I have been collecting recipes for years. What I loved about Tessa's book is that I could see visually what the outcome would be using different ingredients and techniques. I found out by accident that I liked the texture of my cookies when I chilled the dough and baked them off the next day. I'm the kind of person who needs to understand why things turn out the way they do. It has to make sense in my mind. Thank you, Tessa, for considering people like me when you wrote your book. I love the creative aspect of cooking, but I have a deep respect for the scientific part of it as well. I need to know why I succeed or fail.

by Kristin on The Ultimate Cookie Handbook

This book includes wonderful recipes, but it is so much more than that. What I really appreciate is all of the "How To" information. It lists ingredients and their purpose in the recipe. It shows pictures of why your cookies may be turning out a certain way due to your ingredients and how to customize your cookie if you desire. It covers every aspect of making a cookie. The Ultimate Chocolate Chip Recipe is incredible! I absolutely love this book!

by Ada on The Ultimate Cookie Handbook

It's worth EVERY PENNY! This is not your average cookie book with recipes. Yes, she does have yummy recipes. But she literally deconstructs a cookie and gives you the science behind it. Baking soda vs. Baking Powder. How oven rack positioning affects the appearance and the taste. White sugar vs. brown sugar. How to properly measure ingredients (weight vs. volume). This book is chock full of information. It is well organized and written. Thank you so much. I found her randomly on Youtube. Love her videos. I then purchased her ice cream sandwich book (which is also great by the way). This book is pure awesomeness too!!

The Ultimate Cookie Handbook

Do you know what the biggest mistake people make while baking recipes at home? It’s a mistake that’s reflected in so many of the comments, emails, and messages I get from frustrated readers.

The biggest mistake is not treating baking like a science. Luckily you don’t have to understand the complicated chemical reactions involved, but you do have to understand the basics to create beautiful treats consistently.

That’s why I’ve spent months crafting The Ultimate Cookie Handbook so you can become the expert and learn how to bake perfect cookies every time.

Now you have every possible answer to “what went wrong?” or “how do I make my cookies more ________!?” It’s like I’m right there in the kitchen with you! Your cookies no longer have to be a hit-or-miss mystery!

With this handbook, you can become the expert, graduate from cookie culinary school, and finally create your version of every ultimate cookie recipe to delight your friends, family, and your taste buds.

Learn how to create your go-to perfected recipes. Or simply learn how to become fearlessly creative in the kitchen. It is so much more than a cookbook, focusing on giving you a lifetime of knowledge rather than a bunch of variations of the same recipes. In fact, there’s only 16 recipes in this book! But they’re the ones that will end your perfect recipe search.

No, there is no printed version only a digital PDF.

Can I save and share the book among multiple devices? What about giving as a gift?

My goal for this eBook is for you and your family to use and share it just like you would a physical book. You can save it to various computers, smart phones, and tablets in your household. To give as a gift, simply hit one of the buy buttons on this page, then hit the little gift icon on the payment form to allow for gifting.

Are there wheat-free, dairy-free, gluten-free, vegan, low-sugar, etc. recipes?

No. There is ONE “skinny” chocolate chip cookie recipe but beyond that I do not extensively cover dietary restrictions in the book. That would be a book-length topic in itself! I also do not include high-altitude baking information because it is something I have zero experience with.

Is the book only about chocolate chip cookies?

No! The Customization and Troubleshooting chapters can be applied to ANY kind of drop cookie and the Ultimate Recipe chapter includes various cookie recipes, though there is an emphasis on chocolate chip because of its popularity!
