What is an atomic cake made of?

Atomic cake is a beloved dessert in many households across the United States. It’s a multi-layered dessert that features banana cake, chocolate cake, and yellow cake, all stacked together with layers of filling, frosting, and fresh fruit. This iconic dessert has become synonymous with family gatherings, celebrations, and holidays. But, what do we know about the origins of atomic cake, and what is it made of?

In this blog post, we’ll delve into the different components that make up an atomic cake and explore the history behind this dessert.

History of Atomic Cake

Atomic cake has been around for many decades, and it’s timeline can be traced back to the early 1900s. It gained popularity in the 1940s and 1950s when it was a popular dessert served at bakeries, diners, and restaurants. The name ‘atomic’ is believed to be a nod to the atomic bomb, which was a significant cultural reference at the time. It’s not hard to imagine how the multiple layers and colors of an atomic cake might suggest a connection to the structure of an atomic bomb.

Atomic cake gained popularity among the middle class in the mid-20th century as a way to celebrate special events like holidays and birthdays. It was particularly popular in Midwestern states like Wisconsin, Minnesota, and Iowa, where it was even served at state fairs. Today, it remains part of the region’s cultural heritage.

What’s in an Atomic Cake?

An atomic cake is a three-layered cake that combines banana, chocolate, and yellow cake, each one separated by a layer of filling or frosting. There are variations in the frosting and filling used, but in general, you can expect to find:

Base Layer

The bottom layer of atomic cake is typically banana-flavored cake. This cake is baked first, cooled, and then sliced to form the base of the cake. Banana cake is used as a base because it’s tender, moist, and creates a sturdy base for the rest of the layers.

Bavarian Cream

Bavarian cream is a rich, creamy custard that is often used as a filling in cakes, pastries, and pies. It’s lighter than traditional custard and has a smooth, silky texture. For atomic cake, a layer of Bavarian cream is spread over the banana cake. The Bavarian cream is typically a combination of milk, sugar, vanilla, and egg yolks, cooked over low heat until thickened. It’s left to cool before being spread on the cake.

Chocolate Cake

The middle layer of an atomic cake is a rich, chocolate cake. The chocolate cake layer is prepared next and spread with strawberry glaze, followed by sliced strawberries and whipped cream. The chocolate cake layer should be rich and moist, with a deep cocoa flavor.

Yellow Cake

The top layer of the atomic cake consists of yellow cake, baked to perfection. Once it cools, it’s topped with a layer of fudge, which acts as another layer of frosting. The yellow cake layer is studded with additional whipped cream, sliced fruits, and more frosting. The yellow cake should be airy and moist, with a slightly sweet flavor.


Atomic cake is a classic dessert that has been enjoyed by generations over the years. It combines multiple layers of cake, frosting, and fresh fruits in a decadent and flavorful sweet treat. Whether you’re from the Midwest or other parts of the United States, there’s a good chance that you have come across an atomic cake at some point in your life. Now that you know the components that make up an atomic cake, why not try making it at home and indulge in this timeless dessert tradition?


Where did Atomic Cake come from?

Atomic cake is a unique dessert that has its roots in the Midwest United States, specifically Chicago. The cake is a hefty product of many layers of buttercream, cake, and confectionery that are gathered together to make a delicious and eye-catching dessert. There is no definitive answer as to where Atomic cake first originated from, but it is believed to have been around since the 1950s when Chicago bakers began producing the cake.

Many bakeries in the South Side of Chicago including Weber’s Bakery and Tuzik’s Bakery have carried on the tradition of producing Atomic Cakes for over half a century. It is worth noting that Atomic cake’s name may have been influenced by the Cold War era when nuclear bombs were becoming prevalent in pop culture, and the cake’s height and explosion of flavors may have inspired its unique name.

Atomic cakes are typically made with seven layers of cake with fillings of buttercream, mousse, cherry, and banana. The icing is usually made with whipped cream and a variety of frosting flavors. The cake’s many layers are the hallmark of an Atomic cake, making it distinctive from other cakes.

The origin of Atomic Cake is somewhat elusive, and while nobody knows precisely who created them in the first place, their uniqueness and popularity have persevered over the years. Atomic cakes are a beloved treat in Chicago, and their reputation has spread widely across the United States. They continue to be a distinctive dessert, favored by people of all ages and backgrounds.

What was the Atomic Cake controversy?

The Atomic Cake controversy refers to a minor scandal that emerged in late 1946 over the celebration of Operation Crossroads, a series of nuclear weapons tests conducted by the United States in the Pacific Ocean. In August of that year, after the successful detonation of two bombs on Bikini Atoll, the team behind the tests was disbanded, and a few weeks later, a party was held to commemorate the event.

At this party, an “atomic cake” was presented and served to the guests, including Vice Admiral William H. P. Blandy and his wife. The cake was shaped like a mushroom cloud and had frosting that resembled the radioactive fallout. A photo was taken of the Blandys cutting the cake with a ceremonial sword, and it was published in several newspapers and magazines.

However, some people were offended by the cake and saw it as insensitive and tasteless, given the deadly consequences of the nuclear weapons tested in Operation Crossroads. The Women’s Action Committee, a civil rights organization, called for an apology from Vice Admiral Blandy and accused him of trivializing the nuclear tests and their impact on human life.

In response, Blandy defended the cake as a harmless and light-hearted way of celebrating the end of the test program. He argued that the cake had not been intended to mock the victims of nuclear weapons or minimize the seriousness of the tests.

The controversy eventually subsided, but it highlighted the growing concerns about the dangers of nuclear weapons and the need for greater awareness of their destructive power. The Atomic Cake incident also demonstrated the power of images and the media to shape public perceptions of sensitive issues, even when the intention behind them was innocuous.

Is cake super unhealthy?

Cake, like many other sweet treats, can be excessively rich in sugar, fat, and calories. That being said, there are many different types of cake, and some are healthier than others. For example, some types of cake contain healthier ingredients like whole grains, fresh fruit, and nuts while others are high in trans fats, refined flour, and added sugars.

The combination of high levels of sugar and fat can have several negative impacts on your health. Consuming too much sugar can cause weight gain, tooth decay, and increase your risk of developing chronic diseases such as Type 2 Diabetes and heart disease. The high levels of trans fats found in many commercially-made cakes can also contribute to the development of heart disease and increase your “bad” cholesterol levels.

However, if you enjoy cake in moderation and make smarter choices about the type of cake you consume, it need not always be a harmful food. Avoiding refrigerated and pre-packaged cakes can help in reducing the intake of the trans-fats, while choosing cakes made with natural ingredients, fresh fruits, and whole wheat flour can be healthier cake options. Additionally, smaller portions and occasional indulgences can also help in minimizing the damage that cakes can do to your health.

While cake can be a delicious dessert, it can be unhealthy when consumed in excess and when made with less healthy ingredients. It is essential to pay consideration to your overall dietary habits and choose healthier cake options, in appropriate portion sizes, as part of a balanced and varied diet to minimize the potential harmful effects of cake on your health.
