One kilogram (1000g) of plain sponge cake contains 2,890 calories, a kilogram with icing has 3,020 calories, and a kilogram of vanilla sponge cake contains 4,400 calories.

A single serving of sponge cake (370g) contains 983 calories, while a Hostess Twinkie (38g) has 130 calories, and one Lady M Signature Mille Crêpes slice (118g) has 360 calories.

The nutritional upsides of sponge cake are linked to the high proportion of eggs used in the batter. A review of these limited potential advantages is available here.

• Provides High-Quality Protein: Eggs are a primary ingredient, making sponge cake a source of complete protein which is essential for muscle repair and building tissues. A study by Layman, D. K., & Rodriguez, N. R. (2009), "Egg protein as a source of power, strength, and energy," details the role of egg protein in muscle synthesis and overall health.
• Contains Choline for Brain Health: Egg yolks are one of the best dietary sources of choline, a nutrient that is vital for brain development, memory, and neurotransmitter synthesis. A study by Zeisel, S. H., & da Costa, K. A. (2009), "Choline: an essential nutrient for public health," confirms that choline is a critical nutrient for cognitive function throughout life.
• Supplies Selenium: Eggs provide a significant amount of selenium, a trace mineral that functions as a powerful antioxidant and is essential for thyroid hormone metabolism and immune function. A large slice of sponge cake (100g) can provide 26% of the Daily Value for selenium.

The dessert's simple composition presents several health concerns, mainly related to its high sugar and refined flour content. An analysis of these health risks is provided here.

• High in Sugar and Refined Flour: Sponge cake is made with a large amount of sugar and refined white flour, a combination that can cause a rapid increase in blood sugar levels. A scientific statement from the American Heart Association by Johnson, R. K., et al. (2009), "Dietary sugars intake and cardiovascular health," recommends strict limits on added sugar, linking high consumption to an increased risk of obesity and heart disease. A healthier alternative is a hard-boiled egg. A suggested amount is to limit consumption to one small, plain slice on an infrequent basis.
• Low in Fiber and Micronutrients: The use of refined white flour means the cake has very little dietary fiber, vitamins, or minerals, making the dessert a source of "empty calories." A review by Ludwig, D. S., et al. (2018), "Dietary carbohydrates: role of quality and quantity in chronic disease," connects diets high in refined carbohydrates and low in fiber to a greater risk of metabolic diseases.

No, sponge cakes are not a healthy food because the high concentration of sugar and refined flour negates any benefits from the eggs. The cake's impact on metabolic health is negative. The high glycemic index of the cake's ingredients can lead to sharp fluctuations in blood sugar. A study by Brand-Miller, J. C., et al. (2002), "Glycemic index and obesity," found that high-glycemic-index diets may promote overeating and increase the risk of obesity. For dental health, the high sugar content is a primary risk factor for tooth decay. A study by Touger-Decker, R., & van Loveren, C. (2003), "Sugars and dental caries," affirms the direct relationship between the frequency of sugar consumption and the risk of developing dental caries. For liver health, the high sugar content, particularly fructose (from sucrose), can be converted into fat by the liver, potentially contributing to non-alcoholic fatty liver disease over time. A review by Tappy, L., & Lê, K. A. (2010), "Metabolic effects of fructose and the worldwide increase in obesity," explains this metabolic pathway.

No, sponge cake is not a healthy food. The cake is composed almost entirely of refined flour, sugar, and eggs, providing a high number of calories with very few nutrients like fiber, vitamins, or minerals. Such foods are considered sources of "empty calories" and can displace more nutritious foods from the diet. A review by Popkin, B. M., et al. (2012), "Global nutrition transition and the pandemic of obesity in developing countries," discusses how a shift toward energy-dense, nutrient-poor foods is a major driver of the global obesity epidemic. The high sugar content is another primary concern. A meta-analysis by Malik, V. S., et al. (2006), "Intake of sugar-sweetened beverages and weight gain: a systematic review," found clear evidence linking the consumption of sugary items to weight gain. The lack of fiber and low fat content also makes sponge cake less satiating than other foods. 

The ingredients used for fat and leavening determine the calorie count of a sponge cake. A Victoria Sponge has the highest calorie value at 410 calories per 100 grams, a consequence of its high butter content. An Angel Food Cake contains the lowest calorie value at 257 calories per 100 grams, a direct result of having no fat from egg yolks or butter. Chiffon and Genoise cakes fall in between, with the oil in Chiffon cake making the cake higher in calories than a Genoise made with a smaller amount of butter.

Yes, a plain sponge cake is lower in calories compared to most other types of cakes. A plain sponge cake contains around 289 calories per 100 grams. This is because the cake's structure and volume come from whipped eggs rather than large amounts of fat. In contrast, a traditional butter cake or pound cake, which relies on a high proportion of butter for its dense texture, contains around 390 calories per 100 grams. A rich chocolate fudge cake can have over 450 calories per 100 grams, and a dense cheesecake can have over 320 calories per 100 grams. The lower fat content is the primary reason for the sponge cake's lower calorie count.

A sponge cake is served only as a dessert or as a component in a sweet dish. The cake's light, sweet, and delicate character makes the baked good incompatible with savory main courses. A sponge cake is conventionally presented after a meal, either on its own or as the foundation for other desserts.

A slice of cake becomes high in calories when the portion size is large or when the cake is made with high-fat and high-sugar ingredients like buttercream, cream cheese frosting, or dense fillings. A small, plain slice of sponge cake (38g) has only 110 calories. A slice becomes high-calorie when it exceeds 400 calories. A medium slice of vanilla sponge cake (75g) has 330 calories, while a large slice (100g) has 440 calories. Restaurant desserts, like a slice of Godiva Chocolate Cheesecake from The Cheesecake Factory, can exceed 1,300 calories, which is exceptionally high.

The history of sponge cake begins in the Renaissance, with early recipes appearing in both England and Spain. These first cakes, known as sponge biscuits, were thin, crisp, and cookie-like. The creation of the modern, light, and airy sponge cake is credited to Italian pastry chefs in the mid-18th century. The recipe, known as Pan di Spagna ("Spanish bread"), was developed in the kitchens of the Genoese aristocracy. The key innovation was the technique of whipping whole eggs with sugar over heat for a long period to create a stable foam that would act as the sole leavening agent. This method produced a light yet sturdy cake that was unlike anything before. The recipe spread to France, where the cake became known as Genoise, and to England, where the invention of baking powder in the 1840s led to the development of the Victoria Sponge, a simpler version that used chemical leavening.
