Birthday Wishes ... & Struggles: KidLit Confections Allergy-safe Cupcakes

Some of the people I love most have birthdays in September, and so this is a good month to share one of my favorite, most ambitious recipes: Chocolate Cake! ... How is chocolate cake ambitious? Well, this isn't just any chocolate cake. It's allergy-safe for all of the top food allergies, but you'd never know it's not "regular" cake.

(The recipe, including a link to the index of printable PDF files, can be found at the bottom of this post.)

I've had this recipe in the queue to share as an official #KidLitConfections recipe for nearly a year, but I couldn't quite settle on which book to share it with. Because there are so many delicious books that pair well with chocolate cake! How do you pick just one?

So I didn't pick just one. Instead, here are three great books to enjoy with your cake!

The Book:

BIRTHDAY BASH by Blair Northen Williamson and Taylor Woolley

Description from the Publisher:

Set sail for fun, friendship, and a splash of self-awareness with Kiko and his crew!

For fans of Grumpy Monkey and Don't Let the Pigeon Drive the Bus! comes Birthday Bash, an uptight mouse with a party to plan.

A laugh-out-loud adventure that teaches kids how to handle big emotions and find creative solutions!

Kiko the Mouse is determined to host the perfect birthday party aboard his houseboat.

But when a buzzing bug crashes his cupcake preparations, Kiko's frustration leads to a chaotic chain of mishaps--boat holes, gushing leaks, and sinking party plans!

Can Kiko, with the help of his clever friends, keep his cool long enough to patch things up?

Or will his over-the-top reaction sink his party?

Packed with hilarious antics and relatable lessons, Birthday Bash is perfect for kids ages 4-8.

With its vibrant illustrations and playful storytelling, Birthday Bash helps children identify their feelings, laugh at life's messes, and discover that sometimes, even uninvited guests become unexpected friends.

My Thoughts:

Kiko wants everything about his birthday party to be perfect. Especially his gourmet cupcakes. But when a bug tries to sample the treats too, Kiko isn't having it!

After all, a bug in a treat is no fun to eat!

But when his zealous attempts to oust the uninvited guest destroy not just his party but his houseboat as well, Kiko has to work quickly with his friends to fix the mess.

This is a cute story about working together and asking for help when needed. And about letting go of the little annoyances that threaten our idea of what "perfect" is. A story about learning to let it go before the situation gets out of hand (or walking it back to fix things after it did get out of hand).

Also, the illustrations are bright and colorful and the characters are just so cute!! This book is an easy one to read over and over again. Perfect for anyone who sometimes experiences Big Emotions.

Also: BIRTHDAY BASH was published in September 2025, so this month is its book birthday! That makes it extra-perfect to celebrate with some yummy cupcakes!!

The Book:

PAISLEY'S BIG BIRTHDAY by Heather Pierce Stigall and Natallia Bushuyeva

Description from the Publisher:

A sweet story about having patience as we grow. For everyone ages 4 years and up.

Paisley’s birthday is today, right? Then why doesn’t she feel any older? She still has trouble reading, still has trouble jumping in the Hopstacle Course, and is still in Bunnygarten. When will she finally be big?

My Thoughts:

Paisley is excited! Today is her birthday. Which means she is a big girl!! 

Except... Mom says she still has to go to Bunnygarten. No Big Bunny School until next fall. 

And when she tries to read the big words or finish the whole Hopstacle course without help... Paisley stutters and flops. 

Maybe she's not a big girl yet after all? 

This is such a real and relatable emotion! When we hit those life milestones (like birthdays or anniversaries), it can be a bit frustrating to realize "Hey, I don't feel any different than I did yesterday." And sometimes in our frustration with how far we still have to go, we forget to notice how far we've already come. 

Reading this book reminded me of how one of my daughters absolutely sobbed as she was getting close to her third birthday because she didn't know how to read yet. She had heard stories about her big sister learning how to read at age three, so she thought she was so far behind!! But we all have our own race to run. We all have our own strengths and struggles. Arbitrary milestones aren't as important as we sometimes think they are.

The soft, gentle illustration style of this picture book gives it an added layer of coziness, reminding readers to relax and settle in, and to go a bit easier on themselves.

The Book:

THE SECRET BOOKSTORE SLEUTH SOCIETY by Lindsay Currie

Description from the Publisher:

"Currie crafts an enthralling series launch in this locked-room murder mystery... a gripping and expertly cultivated suspense novel." -- Publishers Weekly, STARRED review

In this exciting series starter, four best friends are trapped in a book-themed inn during an ice storm and they must use each of their special skills, as well as a few tips from an armchair-detective grandma, to figure out who killed one of the regular customers. From #1 New York Times bestselling author of The Mystery of Locked Rooms comes a thrilling murder mystery.

Merrick McGee has been having a tough time. When her Grandma Ida gets sick and moves in, the family can't afford to keep sending Merrick to her beloved private school. So, she spends most of her time in the small room at the back of the bookstore/inn her mother works at being homeschooled, bored out of her mind, and lonely for her best friends.

But when an ice storm hits their town, and fate brings her friends together to ride out the storm at the inn with her, she's stoked to finally be able to spend time with the people she loves the most. Until... the unthinkable happens, and someone is found dead--facedown in a birthday cake sitting right at Merrick's own desk.

With the storm picking up the police remove the body and suggest the victim died of old age. But to Merrick it seems more like a murder. Luckily, she and her friends love solving mysteries, and with the suspects all under the same roof, and her friends eager to crack the case--the Secret Bookstore Sleuth Society is born! As the club begins to investigate, more questions come to light, and Merrick soon realizes her own grandmother may be the key to solving the case...

My Thoughts:

Merrick hates that she's home schooled (working every day from her mom's bookstore in a book-themed inn) now that her sick grandma has moved in and they can no longer afford her fancy private school. She's afraid her friends will move on and forget all about her. And nothing's worse, when you're in middle school, than being forgotten!

But when an ice storm hits trapping Merrick and her friends inside the inn for the night (along with their mothers, Merrick's grandma and aunt, the owner of the inn, a couple of employees and a few guests--one of whom is found dead at Merrick's school desk!!), the Secret Bookstore Sleuth Society is born.

Someone has murdered Daniel (an old man who frequents the bookstore, and who Merrick calls "Pipey" because he always carried a tobacco pipe in his pocket). The murderer is still there too, trapped at the inn by the storm, just like Merrick and her friends. And it's up to them to catch the culprit. The police think Daniel died of natural causes so they aren't investigating anything. The Secret Bookstore Sleuth Society will have to solve the case and catch the villain before the storm breaks and a murderer escapes with zero consequences.

Part Nancy Drew, part Scooby-doo, this book is a fun cozy mystery perfectly suited to the middle grade crowd. It has all the angst of first crushes and family drama that makes it super-relatable at that age, and there was just enough puzzle and mystery to keep you turning pages without getting too intense for the audience.

I can't wait to read more books centered around this group!

The Recipe:

This is a recipe I came up with for my daughter's friend when, shortly before her 16th birthday, she discovered that she was allergic to all eight of the most common food allergens, plus gluten. And how can you have a birthday cake that actually tastes good when you have to follow a diet that's free from gluten, dairy, eggs, peanuts, tree nuts, soy, fish, shellfish, and sesame? (Okay, the fish and shellfish are generally not found in birthday cakes... though you'd be surprised how often you see "may contain shellfish..." on ingredient labels!) After much trial and error (and more errors than I'd like to admit), this recipe took shape. Chocolate cake (or cupcakes) good enough that even my "I won't eat gluten free things" friends didn't know they weren't eating "the real thing!

Each of the books in this group has a bit of a "birthday gone horribly wrong" element to it, just like the fear that threatened to ruin Brit's sweet 16. But no matter how frustrating, scary, or disappointing life gets... with a little persistence and creativity, you can always find a way to have your cake and eat it too!

Brit's Allergy-safe Chocolate Cake

 2 c. gluten-free all-purpose flour*

1 ½ c. sugar

2 Tbsp cornstarch*

1 c. cocoa powder*

1 Tbsp. baking powder*

2 tsp. baking soda

1 tsp. salt

½ c. canola oil

1 ¾ c. oat milk

1 Tbsp. vanilla extract

First, check the ingredient lists and labels on ALL of your ingredients! You’d be surprised how many things have hidden dairy, wheat, nuts, or soy (including gluten-free flour, baking powder, baking soda, cornstarch, cocoa powder, oat milk, etc.) I always check labels, even if I've previously checked for that brand, because things sometimes change and you can never be too safe! (Life is not easy when you’re on a restricted diet!)

In a large bowl, combine flour, sugar, cornstarch, cocoa powder, baking powder, baking soda, and salt.

Warm oat milk in the microwave just until small bubbles form (not a full boil). Add oil and vanilla to the oat milk, then pour into the dry ingredients.

Mix just enough to combine.

Pour a few drops of canola oil into a 13x9-inch glass cake pan and use a clean paper towel to spread the oil. (Cooking spray usually contains soy lecithin, so that’s not usually the best option for greasing the pan.) Or line muffin cups with paper or silicone liners.

Spread batter in the prepared pan and bake in a preheated 350F oven for 30-35 minutes for cake or 25-28 minutes for cupcakes, until a cake tester inserted into the center comes out clean.

Dust warm cake with powdered sugar. Or let it cool completely and frost with icing of your choice.

* I used King Arthur brand flour, Argo brand cornstarch, Hershey’s Special Dark Cocoa Powder, and my local store-brand baking powder and baking soda, which were both safe options.

 

This recipe, originally created for Brit Mason, pairs well with BIRTHDAY BASH by Blair Northen Williamson and Taylor Woolley, PAISLEY'S BIG BIRTHDAY by Heather Pierce Stigall and Natallia Bushuyeva, and THE SECRET BOOKSTORE SLEUTH SOCIETY by Lindsay Currie
