December 4, 2025 •

4 min read

According to nutritional data, a single scoop (around 1/2 cup) of key lime pie ice cream can range from 150 to over 270 calories, depending on the brand and ingredients. This calorie count is influenced by factors such as fat content, sugar levels, and the inclusion of swirls and cookie pieces that make this flavor so distinct.

Quick Summary

Calorie counts for a scoop of key lime pie ice cream vary widely by brand and serving size. Factors like fat, sugar content, and mix-ins influence the total number. Understanding these differences helps in making informed choices.

Key Points

Variable Calorie Count: The number of calories in a scoop of key lime pie ice cream can range significantly, typically from 150 to over 270 calories for a 1/2 cup serving, depending on the brand.
Ingredient Impact: Factors like the fat content from cream, added sugars from condensed milk and syrups, and mix-ins such as graham cracker crust all contribute to the final calorie count.
Serving Size Matters: The size of a "scoop" is inconsistent; using a measuring cup to stick to a 1/2 cup serving size is crucial for accurate calorie counting.
Brand-Specific Information: Brands like Blue Bell (approx. 170 kcal per 1/2 cup) and Ben & Jerry's (approx. 270 kcal per 1/2 cup) have different nutritional profiles, emphasizing the need to check specific product information.
Lighter Options Exist: Healthier alternatives include homemade protein-based ice creams using yogurt or cottage cheese, as well as lower-fat frozen yogurt versions.
Mindful Consumption: Practicing portion control and balancing the treat within a healthy diet are the best ways to enjoy key lime pie ice cream responsibly.

Understanding the Calorie Variability

The number of calories in a scoop of key lime pie ice cream is not a fixed number. It varies significantly based on several factors, including the manufacturer, the size of a "scoop," and the specific ingredients used. A standard serving is often listed as a 1/2 cup, but many scoop shops and home servings are more generous. Commercial brands like Blue Bell might offer a different calorie profile than a specialty brand like Ben & Jerry's, or a small local scoop shop. For instance, a 1/2 cup serving of Blue Bell Key Lime Pie Ice Cream is listed at 170 calories, while a similar size from Ben & Jerry's is 270 calories, and a different brand might come in at 150 calories.

Key Factors Influencing Calorie Count

Fat Content: Full-fat dairy is a major contributor to the calorie count. Brands using richer cream will have a higher fat content and, consequently, more calories per serving.
Sugar and Sweeteners: Ice cream recipes use a combination of sugars and syrups. High-fructose corn syrup and condensed milk, common ingredients in the "pie" swirl, significantly increase the sugar and calorie load.
Mix-ins: The graham cracker crust pieces and whipped cream swirls are a major part of the key lime pie flavor. However, these additions also increase the carbohydrate and fat content, boosting the total calories.
Serving Size: The definition of a "scoop" is inconsistent. A standard measure is 1/2 cup, but a generous hand-scooped portion could be double that, dramatically increasing the total calories consumed.

Calorie Comparison by Brand

To provide a clearer picture, here is a comparison of the calories in a typical 1/2-cup serving of key lime pie flavored ice cream from various brands, based on available nutrition facts.


Brand	Serving Size	Calories (Approx.)	Fat (g)	Sugar (g)
Blue Bell	1/2 cup	170	8	16
Maggie Moo's	1 scoop	190	9	24
Ben & Jerry's	1/2 cup	270	13	20
Perry's Frozen Yogurt	2/3 cup	210	7	N/A
Hershey's Ice Cream	2/3 cup	240	N/A	N/A

Note: Serving sizes may differ slightly depending on the specific product and formulation. Always check the nutrition label on the product packaging for the most accurate information.

Healthier Alternatives and Considerations

For those looking to enjoy the key lime pie flavor with fewer calories, several alternatives exist. Many home cooks are creating their own healthier versions of this popular dessert.

Homemade Protein Ice Cream: Using a blender and protein powder, you can make a high-protein, low-sugar version of key lime pie ice cream. Some recipes utilize Greek yogurt or cottage cheese for a creamy base.
Frozen Yogurt: Opting for a key lime pie frozen yogurt can often reduce the calorie and fat content compared to traditional ice cream. However, still be mindful of sugar content, which can sometimes remain high.
Sorbet or Fruit Ice: A key lime sorbet or fruit ice eliminates the dairy base, resulting in a fat-free dessert. While still high in sugar, it provides a different, lighter experience.
Portion Control: Even with a high-calorie option, managing portion size is key. Stick to the suggested 1/2 cup serving to keep calories in check.

The Role of Ingredients in Calorie Density

The specific ingredients play a critical role in the calorie density of the finished product. A recipe that is primarily cream and sugar will be much more calorie-dense than one made with milk and alternative sweeteners. The addition of graham cracker pieces, condensed milk swirls, and other high-sugar additions can push a seemingly modest serving into the higher calorie ranges. Understanding the ingredient list is the best way to predict a flavor's nutritional impact.

Conclusion: Navigating Your Dessert Choice

The calorie content of a scoop of key lime pie ice cream is not uniform and depends heavily on the brand, portion size, and recipe. With commercial brands varying widely—from around 170 calories to over 270 calories per standard serving—it's essential to check the nutritional information. For those seeking a lower-calorie option, making a homemade protein-based version or choosing a frozen yogurt alternative can be a good choice. Ultimately, enjoying this classic flavor is about balancing indulgence with mindful portion control to fit your dietary goals.

How to enjoy key lime pie ice cream mindfully

Read Labels: Always check the nutrition facts, especially the serving size, before scooping.
Measure Portions: Use a measuring cup instead of free-scooping to ensure accurate portion control.
Balance with a Healthy Diet: Enjoy this treat as an occasional indulgence, balanced by nutrient-dense foods in your regular diet.
Explore Alternatives: If calories are a major concern, try homemade high-protein versions or lighter frozen yogurt options.
Focus on the Experience: Savor the flavor and texture of every bite to feel more satisfied with a smaller portion.
