Have you ever heard of Thunder Cake?

If you have a child who is nervous about thunderstorms, this sweet story and recipe activity can help turn fear into a cozy memory.

The picture book Thunder Cake by Patricia Polacco is a wonderful way to talk about storms, bravery, and family traditions. Even better — it includes a chocolate cake recipe you can make together while a storm rolls in.

My Love of Thunderstorms

When I was growing up in southern Florida, thunderstorms were a daily summer event. The rain was warm, the drops were huge, and the lightning shows were incredible.

I loved running outside to dance in the rain and splash through the giant puddles afterward. Florida storms can be powerful and beautiful at the same time.

But not every child feels that way.

Some kids are frightened by thunder and lightning. A comforting story and a hands-on activity can be a wonderful way to help them feel a little braver.

There are many kids who have a fear of thunderstorms. Some of my kids have feared storms at times. If you have a child who is afraid of thunderstorms, read on!

About the Book Thunder Cake

In Thunder Cake, a young girl becomes frightened as a storm approaches. Instead of letting fear take over, her grandmother (babushka) gives her a mission: they must bake a Thunder Cake before the storm arrives.

As the storm gets closer, they gather ingredients around the farm:

• Eggs from the chickens

• Milk from the cow

• Chocolate, flour, and sugar from the pantry

Along the way, Grandma teaches her to count the seconds between lightning and thunder to determine how far away the storm is.

Each number represents about one mile of distance.

The storm slowly approaches as they gather ingredients and prepare the cake. By the time it goes into the oven, the girl realizes she has done something brave — she came out from hiding and faced the storm.

Soon they are sitting by the window together, enjoying cake while the thunder rolls outside.

It’s a beautiful story about courage, comfort, and family.

A Simple Science Tie-In

You can also turn this story into a quick science lesson. When lightning flashes, count the seconds until you hear thunder. Every five seconds equals about one mile away.

Kids love testing this during storms, and it makes the experience feel less mysterious and scary.
