It's a really cute story with beautiful illustrations. The fact that Paul can draw at this level with only 10% eyesight is incredible and shows that nothing is impossible with enough determination and heart.

Absolutely adorable little story! The illustrations are incredible! I follow Paul (and Matthew of course) on TikTok, & watching him create these beautiful drawings while dealing with 90% vision loss is amazing. He was born with Retinitis Pigmentosa which is incurable, but it doesn’t stop him from following his dreams and doing what he loves. If you are ever in need of a laugh or a smile, look them up. You won’t regret it! Plus, you might get to see Mr Maple who is simply adorable. Hoping he gets his own book soon!

Pringle and Finn make special cakes, and each one has a secret ingredient. The secret ingredient tends to be just what the party guests need.

From courageous crocodiles to patient sloths, this book has a lot of fun characters, all crafted with a cozy art style. The ending is sweet and satisfying, perfect for a book about cakes.

I really enjoyed this sequel to “The Pengrooms.” Perfect choice for Pride Month and a book children I watch really enjoyed. So happy for them making a change to their lives. The illustrations are still super cute. Definitely hope there would be another book with the penguin family.

When Paul first posted on TikTok the video of his book being “banned” and returned by a bookseller, I immediately ordered a copy for our family. I’ve been growing our 3-year-old’s library, and I try to include as much as I can that fosters empathy, inclusivity and diversity. As a cishet white person, I think it’s important for her to see that not all families look like ours, and that’s okay! Well, after over three months of waiting, the book FINALLY made it! (Did I mention it sold out?!) Let’s just say it was an instant hit! The illustrations are darling, the story is sweet, and the message is simple: love.

Another adorable cake-themed adventure featuring Pringle and Finn. In this one, the penguin couple delivers various birthday cakes to their animal friends until it's time for a very special birthday cake and a new addition to the family.

Sweet artwork with lovely details. A gentle story that makes for a soothing read.

These two are so cute and I love getting little glimpses into their lives.

i bought this specifically because i loved the concept of an inclusive children’s book that highlights and normalizes all types of families. the target audience is kids who have 2 moms, 2 dads, etc. Paul has lost 90% of his vision and yet still managed to draw such beautiful illustrations. i love watching Paul, Maple (his guide dog) and Matthew’s tiktoks. when he posted the video talking about the bookstore that wanted to return the 100 copies they ordered because the content “didn’t adhere to their policies”, i knew i needed a copy for myself. this book was SO sweet and adorable. 5 stars

Youtube’s algorithm suggested a video of the author talking about how this book had been banned by a bookstore. So of course I read it, and I have to say, it is so cute. Among the cuter children’s books I’ve read. It’s about two penguins who bake and deliver cakes for birthdays. It is LGBTQ friendly, which I suppose is why it got banned, but honestly, it’s just a cute children’s book with a good message.

This was a super sweet story with love and creativity strongly represented. The sloth family made me grin extra too but what blows my mind is that Paul illustrated this book too. He has lost nearly all of his vision due to a eye condition yet has these amazing detailed illustrations throughout. I've seen videos where he explains the creative and resourceful ways he utilizes to view art. Now I want to know more about how he creates art.

This one was super cute as well!!

I absolutely love how paul can bring the characters to life. And make the cakes super personalized

This time, they’re making birthday cakes. At each delivery, they learn how to do something by tapping into a certain quality (known as the secret ingredient)

Until the last delivery is a BIRTH day cake!! 🥺❤️

Absolutely amazing book. We read this with the girlscouts and the representation from this book really helped a few of the kids move past their insecurities of their home lives. Getting a copy for my cousins when I can, but it is definetly worth the read.

Happy Pride!

A sweet story for children. The story is simple, sweet and the illustrations is nice and colorful.

The most surprising thing is the illustrator is legally blind.

Nice for him to realize his dream.

Disclaimer: this is a review bomb as a response to the intolerant people who banned this book because it violates their "policy". How does this book harm anyone honestly???

Nicely drawn and with a nice message about accepting different types of families, but the central conceit of the special ingredients doesn't really work, so the book doesn't flow.

The Secret Ingredient is LGBTQ friendly that got banned from a bookstore which is the reason I bought it. However it's just a cute children's book with a great message and gorgeous illustrations.
