Decoding the Data: Which Cakes Are Sugar-Packed?
Determining what kind of cake has the most sugar is not always a straightforward answer, as the amount can vary wildly by recipe, brand, and preparation. However, nutritional surveys and studies provide clear evidence pointing toward certain types that consistently rank higher than others. A prominent 2018 study conducted by the research group Action on Sugar and published in the British Medical Journal found that Battenberg cakes topped the list for sugar content per 100g, followed closely by other specific varieties.
The Heavy Hitters: Battenberg, Genoa, and Red Velvet
The Action on Sugar survey, which analyzed 381 cakes from UK supermarkets, revealed some interesting findings on cake sugar content.
- Battenberg: This distinctive marzipan-covered cake ranked highest, with an average sugar content of 56.4g per 100g. The high sugar content is largely attributed to the sugary marzipan layer and apricot jam used to bind the pieces. In fact, some individual Battenberg cakes were found to have up to 62g of sugar per 100g.
- Genoa Cake: This rich, fruit-filled cake, with its added dried fruits, contained the second-highest amount of sugar, averaging 45.9g per 100g.
- Red Velvet Cake: A favourite for its rich flavour and striking colour, red velvet came in third with an average of 44.2g of sugar per 100g. This high figure is often driven by the large quantity of cream cheese frosting, which can be exceptionally sugary.
The Role of Frosting and Fillings
While the cake base itself contributes significantly to the total sugar, it is often the additions that push certain varieties into the highest sugar categories. Frosting is a primary culprit. For example, a commercially prepared frosted vanilla cake can contain up to 40g of sugar per single serving, demonstrating how much sweetness the icing layer can add. Similarly, other heavy frostings and fillings, like those in coffee and walnut cake (24.9g per serving), heavily contribute to the overall sugar load.
Factors Increasing Sugar Content
- Dense Icing and Frosting: Buttercream, fondant, and ganache-style icings often contain large amounts of powdered sugar. The thicker the layer, the higher the sugar content.
- Fruit Fillings and Jams: Varieties like Genoa and Battenberg use sugary jams or candied fruits for flavour and texture, which adds to the overall sugar mass.
- Commercially Prepared vs. Homemade: Branded, commercially prepared cakes generally have a slightly higher sugar content than supermarket own-label versions, though the difference is not always significant. Commercial recipes often prioritize shelf life and consistent sweetness, often with more sugar.
- Added Ingredients: Chocolate cake and other flavoured varieties require additional sugar to balance out the bitterness of ingredients like cocoa powder.
Comparison Table: High-Sugar vs. Lower-Sugar Cakes (g per 100g)
| Cake Type (per 100g) | Average Sugar Content | Key Contributing Factors |
|---|---|---|
| Battenberg | 56.4g | Marzipan, jam, processed ingredients |
| Genoa | 45.9g | Dried fruits, sugary base |
| Red Velvet | 44.2g | Cream cheese frosting, sugary base |
| Chocolate Cake Bar | 43.3g | Chocolate, frosting, commercial recipe |
| Blueberry Muffin | 24.6g | Often uses less sugar, fruit provides some sweetness |
| Sponge Cake (Victoria) | 38.1g (variable) | Can range widely depending on filling/icing |
The Spectrum of Sugar: From Battenberg to Blueberry Muffins
It is important to recognize that sugar levels can fluctuate greatly, even within the same category of cake. The Action on Sugar survey found a significant range within Victoria sponge cakes, from as low as 23.4g to as high as 59.2g per 100g. This demonstrates that not all Victoria sponges are created equal and that ingredient ratios and recipes play a crucial role in determining the final sugar count. Factors like the proportion of sugar to flour and the amount of fat and eggs used can affect texture and flavour, which in turn influences the amount of sugar required.
How to Manage Sugar Content in Cakes
For those who love cake but want to be mindful of their sugar intake, there are ways to enjoy a treat without overindulging. Choosing naturally sweetened cakes, adjusting recipes, and opting for smaller portion sizes can all make a difference. Some bakers find success experimenting with alternative sweeteners or relying on the sweetness of fruit.

Lower-Sugar Cake Alternatives
- Angel Food Cake: Known for its light, fluffy texture, this cake uses whipped egg whites and typically has a lower sugar content than its heavily frosted counterparts.
- Fresh Fruit-Based Cakes: Cakes that rely on ripe fruit, such as bananas or berries, for sweetness can use less added sugar.
- Simple Sponge with Light Glaze: Opting for a plain sponge cake with a simple powdered sugar glaze or fresh fruit can drastically cut down on sugar compared to a multi-layered, heavily frosted cake.
- Homemade Cakes: When baking at home, you have full control over the sugar content and can often reduce the amount a recipe calls for, as sugar also serves other functions like tenderizing the batter.
Conclusion
While a definitive single answer to "what kind of cake has the most sugar" is difficult due to recipe variations, the evidence suggests that commercially produced Battenberg cakes, followed by Genoa and Red Velvet, consistently lead the pack in sugar concentration per 100g. The main drivers of high sugar content are heavy frostings, marzipan, and sugary dried fruit inclusions. However, by understanding these factors, you can make more informed choices, whether you're selecting a store-bought dessert or baking your own, and still enjoy a delicious cake while managing sugar intake. The wide variation within cake categories also shows that opting for simpler, homemade versions or those with light glazes can significantly reduce the amount of sugar consumed.
