How Many Calories In A Iced Lemon Pound Cake?

Introducing Iced Lemon Pound Cake

Iced lemon pound cake is a moist, rich cake made with lemon juice and zest mixed into the batter. It is a variation on traditional pound cake that incorporates citrus flavors. After baking, the cake is iced or glazed with a tangy lemon icing or glaze to complement the lemon taste in the cake.

Lemon pound cake is a popular cake variety. The combination of buttery vanilla cake with bright, fresh lemon makes it a crowd-pleasing dessert. It is often served at parties, potlucks, and other gatherings. Iced lemon pound cake is also commonly found at bakeries and coffee shops.

Counting Calories

Calories are a unit of energy. Specifically, calories with a capital C refer to kilocalories, or kcal. One calorie is the amount of energy needed to raise the temperature of 1 kilogram of water by 1°C (1). So a Calorie, or kilocalorie, is 1000 times larger than a calorie. The kcal is the most suitable unit of measurement for food and beverages because there is a large amount of energy stored in their molecules (2, exact_sources)

When we eat food, we take in calories that our bodies can use for energy and functioning. The calories in food provide us with fuel for physical activity and other metabolic processes. Consuming more calories than our bodies burn off through exercise and daily living causes weight gain over time. Burning more calories than we ingest leads to weight loss (3, exact_sources).

Understanding calories is important for maintaining a healthy weight and nutrition. Tracking calories can help ensure you get enough fuel without consuming excess energy. Calorie needs vary based on age, gender, and activity level (1, exact_sources).

Calories in Cake Ingredients

The main ingredients in an iced lemon pound cake and their approximate calorie counts per 100g are:

  • Flour – 364 calories (Source)
  • Sugar – 387 calories (Source)
  • Butter – 717 calories (Source)
  • Eggs – 143 calories (Source)
  • Lemon juice – 29 calories (Source)
  • lemon pound cake is a rich, indulgent cake that should be eaten in moderation as part of a balanced diet.

  • Lemon zest – 17 calories (Source)

By combining the calories from each ingredient, we can estimate the total calories in an iced lemon pound cake.

Calories in Icing

The icing is one of the main contributors of calories in a lemon pound cake. Traditional lemon pound cake recipes call for either a lemon glaze or lemon frosting on top of the cake.

A standard lemon glaze made with powdered sugar, lemon juice and zest contains approximately 50 calories per tablespoon. So a cake iced with 1/2 cup of lemon glaze would add about 200 calories from just the icing alone.

Similarly, lemon frostings like Pillsbury’s Creamy Supreme Lemon Frosting contain around 140 calories per 2 tablespoons. A frosted cake with 1 cup of lemon frosting could have over 500 calories just from the frosting.

In summary, traditional lemon icings and frostings can contribute 200-500+ calories to an iced lemon pound cake depending on the amount used.

Standard Serving Size

The typical serving size for iced lemon pound cake is around one slice. A slice or single serving is generally between 100-150 grams in weight.

For example, Hostess iced lemon pound cake labels its slices as 105 grams each. Meanwhile, Starbucks’ iced lemon loaf considers a single serving to be 126 grams.

So in most cases, you can expect a single slice or standard serving of iced lemon pound cake to weigh somewhere between 100-150 grams or 3-5 ounces.

Calories per Serving

A standard serving size of iced lemon pound cake is generally one slice, which weighs around 4.4 ounces or 125 grams. According to CalorieKing, there are approximately 470 calories in one 4.4 ounce slice of iced lemon pound cake.

This serving size and calorie count is consistent across most major nutrition sources. For example, according to EatThisMuch, one slice (4 oz) of lemon pound cake with icing contains approximately 540 calories.

So in summary, a standard serving of around 4 ounces of iced lemon pound cake contains 470-540 calories.

Calorie Ranges

Calorie counts for iced lemon pound cake can vary quite a bit depending on the specific recipe, ingredients, and bakery. Here are some typical calorie ranges per slice:

  • Homemade recipes: 300-500 calories
  • Bakery slices: 350-550 calories
  • Pre-packaged slices: 400-600 calories

For example, a slice of iced lemon pound cake from Starbucks contains around 470 calories. Meanwhile, a supermarket bakery slice may have 380 calories. The calorie differences come from factors like the amount of icing, oil, eggs, and lemon extract used.

In general, homemade cakes tend to be on the lower end of the calorie range since they use less icing and modest amounts of ingredients. Bakery and pre-packaged cakes may be larger or more decadent, pushing the calories upward.

Ways to Reduce Calories

There are several ways to lower the calorie count in iced lemon pound cake while keeping it tasty:

  • Use egg whites instead of whole eggs. Two egg whites have about 34 calories compared to 160 for two whole eggs.
  • Replace butter with lower calorie substitutions like unsweetened applesauce or mashed banana. This can save around 100 calories per 1/4 cup.
  • Swap out all-purpose flour for a lower calorie alternative like almond flour or whole wheat flour.
  • Reduce the amount of sugar. Try using a lower calorie sweetener like stevia or monk fruit.
  • Substitute Greek yogurt for sour cream in the icing. Plain Greek yogurt has fewer calories and higher protein.
  • Use reduced fat cream cheese in the icing instead of full fat. This saves around 50 calories per ounce.
  • Cut back on icing thickness. A thinner layer means less calories per slice.
  • Bake cake layers in mini or cupcake pans. The smaller size equals fewer calories per serving.

With smart substitutions and smaller portions, it’s possible to enjoy iced lemon pound cake while reducing the calorie count by 30% or more per slice.

Health Impact

While iced lemon pound cake can be a tasty treat, it is high in calories, sugar, and fat, so it should be enjoyed in moderation as part of an overall balanced diet. One slice of iced lemon pound cake from Starbucks contains around 470 calories, 63g of carbohydrates, 18g of fat, and 37g of sugar (source).

Consuming foods high in refined carbohydrates like cake can cause spikes in blood sugar and insulin levels, which may negatively impact energy levels and appetite control. The American Heart Association recommends limiting added sugar intake to no more than 36 grams per day for men and 25 grams per day for women (source). One serving of iced lemon pound cake exceeds this daily limit.

While the cake provides some calcium and iron, it lacks other essential nutrients like fiber, protein, and healthy fats. Overconsumption may contribute to weight gain and associated health risks. However, enjoying cake occasionally as part of a balanced diet is unlikely to have significant negative effects for most healthy individuals.

Those looking to reduce the calorie and sugar content could opt for a smaller portion, share with others, or replace half the cake with fresh fruit. Overall, moderation and variety are key when incorporating sweeter baked goods into a nutritious diet.


Iced lemon pound cake is a delicious and refreshing dessert, but like many cakes and desserts, it does contain a significant amount of calories. In this article, we learned that a standard serving size of iced lemon pound cake (around 1 slice) contains 250-350 calories on average. The key ingredients that contribute to these calories are the butter, sugar, eggs, and flour in the pound cake itself, along with the sweet icing topping.

While iced lemon pound cake is high in calories, there are some simple ways to reduce the calorie count if you want a lighter dessert option. Using less butter and sugar when baking, and opting for a lighter icing or fruit topping rather than heavy icing can help lower the calories per slice. As with any dessert food, moderation and portion control is also key.

Overall, while iced lemon pound cake does contain a high amount of calories, it can still be enjoyed in moderation as part of an otherwise balanced diet and active lifestyle. Tracking serving sizes carefully and being mindful of ingredients can help keep the calorie count reasonable.
