How Many Calories Are in One Slice of Crepe Cake? A Comprehensive Nutritional Guide

November 7, 2025 •

4 min read

The calorie count for a single slice of crepe cake can range dramatically, from fewer than 200 to over 600 kcal, depending heavily on the specific recipe and portion size. Consequently, the answer to how many calories are in one slice of crepe cake is not straightforward and requires a closer look at the ingredients.

Quick Summary

The calorie count for a slice of crepe cake is not uniform, as it's determined by the richness of the filling, butter content, and sugar used. The slice's size and whether it's homemade or store-bought also significantly impact its total nutritional value.

Key Points

Significant Calorie Variation: The number of calories in a crepe cake slice varies dramatically, from under 200 to over 600 kcal, depending on the recipe and portion size.
Rich Fillings Add Most Calories: Fillings containing heavy cream, cream cheese, or condensed milk are the most significant contributors to the overall calorie count.
Homemade Offers Control: Making your own crepe cake allows you to control ingredients and portion sizes, enabling lower-calorie modifications like using skim milk or less sugar.
Portion Size Matters: Because slices are not standardized, the total calorie count for the cake must be divided by the number of servings to get an accurate per-slice estimate.
Recipe-Specific Variations: Different recipes for the same type of crepe cake can have wildly different calorie counts due to ingredient and quantity variations.
Homemade Calculation is Possible: For homemade crepe cakes, you can calculate the calories by summing all ingredient calories and dividing by the number of servings.
Consider Added Sugars and Fats: Be mindful of toppings like chocolate, glazes, and extra butter, as these can quickly add significant calories.

Understanding Crepe Cake Calories

A crepe cake, or mille crêpe, is an elegant layered dessert made from dozens of thin crepes stacked with a rich filling, typically a pastry cream or mousse. The individual crepes themselves are relatively low in calories, but the total cake is a different story. The calorie count becomes substantial due to the filling and the total number of layers. A key takeaway is that different recipes, ingredients, and portion sizes lead to a wide spectrum of caloric values. For instance, a Thai Tea Crepe Cake has been reported to contain 396 kcal per slice, while another chocolate crepe cake recipe lists 601 kcal per serving.

The Impact of Ingredients on Calorie Count

To understand the caloric makeup of a crepe cake, consider the key components. Each ingredient contributes a certain amount of energy, and some are more calorically dense than others. Here’s how common ingredients influence the final number:

Filling: The most significant factor. Rich fillings made with heavy cream, cream cheese, condensed milk, and high amounts of sugar contribute the most calories. For example, a slice with a rich condensed milk and cream cheese filling will be far more caloric than one with a lighter whipped cream or fruit-based filling.
Crepe Batter: While thin, the crepes add up. Ingredients like eggs, butter, flour, and milk form the batter. The type of milk (whole vs. skim) and the amount of butter used play a role.
Add-ins and Toppings: Ingredients like chocolate, tea powders (like matcha), fruit, and glazes can further increase the calorie density.

Factors Influencing Crepe Cake Calories

Homemade vs. Store-Bought Crepe Cakes

When you make a crepe cake at home, you have full control over the ingredients, which allows for healthier modifications. Store-bought or restaurant versions, especially those from specialty bakeries, often prioritize flavor and richness, resulting in a higher calorie count per slice. Homemade recipes can be adapted by using skim milk, reducing sugar, and opting for lighter fillings, but this isn't possible when purchasing pre-made cakes.

Portion Size and Slice Dimensions

Serving size is not standardized. What one recipe calls a serving might differ greatly from another, or from what's served at a restaurant. A recipe specifying 8 servings will yield larger, more caloric slices than one that yields 12 or more servings from the same size cake. Therefore, it’s essential to consider the cake's total calories and divide by the number of servings to get an accurate per-slice estimate.

How to Calculate Calories for a Homemade Crepe Cake

For those who bake their own, determining the calorie count is straightforward. You will need to:

List all ingredients and their exact quantities.
Use a reliable nutrition calculator or app (like the one mentioned by Verywell Fit) to get the total calories for the entire recipe.
Divide the total calories by the number of slices you plan to cut. For example, if a full cake is 4,970 calories and you cut 10 slices, each slice is 497 calories.

Calorie Comparison: Different Crepe Cakes

The table below illustrates how different types of crepe cakes can vary significantly in their caloric content, based on available recipe data. The key factors affecting the number are the ingredients and portion size.


Type of Crepe Cake	Calories Per Slice (approx.)	Recipe Source/Flavor Profile	Key Calorie-Increasing Factors
Strawberry Crepe Cake	292 kcal	User-submitted recipe (Calforlife)	Lighter filling, fruit
Crepe Cake (Natasha's Kitchen)	346 kcal	All-purpose flour, cream filling	Standard flour and cream
Matcha Mille Crêpe Cake	396 kcal	Instagram Post	Matcha powder, cream, sugar
Crepe Cake (Simply Quinoa)	442 kcal	Simply Quinoa recipe	Higher-fat ingredients, smaller serving size assumed
Crepe Cake (The Spruce Eats)	497 kcal	Rich cream cheese filling	Rich filling, standard recipe
Chocolate Crepe Cake	601 kcal	Anna Banana recipe	High amounts of butter, rich chocolate cream
OREO Base Crepe Cake	820 kcal	Mondelez recipe	OREO base, rich filling and toppings

Conclusion

In short, there is no single answer for how many calories are in one slice of crepe cake. The calorie count depends entirely on the recipe, the quality of ingredients, the type of filling, and the final size of the slice. While some versions can be moderately low in calories, particularly with careful ingredient selection, many popular recipes and store-bought versions are very high in fat and sugar, leading to a much higher calorie count. Therefore, calorie counters should always check specific nutritional information for their chosen recipe or product, or use a reliable recipe calculator when baking at home. Knowing the ingredients and portion size is key to making informed dietary choices.

Frequently Asked Questions

There is no single average, as calories vary widely based on the recipe and ingredients. Estimates from different recipes range from approximately 290 kcal for a lighter version to over 600 kcal for a richer, chocolate-heavy cake.

The filling is often the biggest factor determining the calorie count. Rich fillings with ingredients like heavy whipping cream, condensed milk, and cream cheese add significantly more calories than lighter options, such as a plain whipped cream or fruit-based filling.

Homemade versions offer more control over ingredients, allowing for potentially healthier choices like using lower-fat milk, less sugar, and lighter fillings. Store-bought cakes often use high-fat and high-sugar ingredients for a richer flavor profile, resulting in a higher calorie count.

To reduce calories, consider using skim milk instead of whole milk, opting for a lighter filling like low-fat Greek yogurt, or reducing the amount of sugar. You can also incorporate more fruit for natural sweetness and bulk.

Yes, portion size is critical. A cake cut into 8 large slices will have a much higher calorie count per slice than the same cake cut into 12 smaller slices. Always clarify the serving size when comparing calories.

Both butter and sugar are calorically dense. Using generous amounts of melted butter in the crepe batter or a high amount of sugar in the filling can dramatically increase the total calorie count of the cake. Reducing these ingredients is a key strategy for a lower-calorie dessert.

A single plain crepe is relatively low in calories (around 90-150 kcal for a 10-inch crepe). A crepe cake, however, contains many layers of these crepes plus a high-calorie filling, so the final per-slice count is much higher.
