How Many Calories Are in One Slice of Jiffy Cornbread?

November 4, 2025 •

5 min read

According to one nutrition database, a standard 1/9th slice of Jiffy cornbread can contain around 237 calories when prepared with milk and egg. However, the exact calorie count for how many calories are in one slice of Jiffy cornbread can vary significantly depending on the recipe modifications and serving size.

Quick Summary

The calories in a single slice of Jiffy cornbread depend on preparation methods and serving size. A typical slice averages over 200 calories, but can be higher or lower depending on ingredients like milk, butter, or sweet additions.

Key Points

Standard Slice Calories: A typical 1/9th slice of Jiffy cornbread prepared with milk and egg contains approximately 237 calories, but can fluctuate based on preparation.
Serving Size Matters: The number of calories per slice is highly dependent on how large or small you cut your portion from the pan.
Ingredient Impact: The type of milk (skim vs. whole), presence of added butter, or mix-ins like cheese significantly affect the final calorie count.
DIY Calculation: The most accurate way to know the exact calories for your specific recipe is to calculate the total calories from all ingredients and divide by the number of slices.
Lighter Options: You can lower the calorie count by using low-fat milk, a non-stick spray instead of butter, and limiting extra sugary or fatty ingredients.

The Core Calorie Count: Understanding the Baseline

Jiffy Corn Muffin Mix is a popular pantry staple, but the calorie information provided on the box often refers to the dry mix or a specific serving size that may not align with a typical square slice from a pan. For a classic preparation using milk and egg, nutritional tracking websites provide a good baseline. For instance, some sites report around 237 calories for a 1/9th share of a pan, while others list 173 calories for a more generic serving. This discrepancy highlights the importance of being precise about what constitutes "one slice." A slice cut into 9 equal squares from a standard pan will be different from a larger, more generous portion.

How Ingredients Impact Calorie Count

When you prepare Jiffy cornbread, the ingredients you add play the most significant role in determining the final calorie count per slice. The standard recipe calls for an egg and milk, but substitutions or additions can dramatically alter the nutritional profile. Understanding these variables is key to managing your caloric intake.

Milk Fat Content

Skim Milk: Using skim milk instead of whole milk will reduce the fat and calorie content. This is one of the simplest ways to make a lighter version without sacrificing much on texture. Whole milk preparations are typically higher in calories.
Whole Milk: The original mix typically assumes whole milk, which contributes a notable amount of calories and fat. If you are baking with whole milk, your calorie count will be on the higher end of the spectrum.

Added Fats and Sweeteners

Butter: Many recipes suggest adding melted butter to the batter or brushing it on top of the finished cornbread. This is a quick way to add significant calories. One tablespoon of butter can add over 100 calories to the entire batch, which is then distributed across each slice.
Sugar and Honey: For a sweeter flavor, some people add extra sugar or honey. Each tablespoon of added sweetener contributes extra carbohydrates and calories that were not in the original mix. For example, a single tablespoon of honey adds approximately 64 calories.

Comparison Table: Calorie Variations

To illustrate the impact of different preparations, here is a comparison table for one slice (assuming a 1/9th serving of a standard 8.5 oz box):


Preparation Method	Key Ingredients	Approximate Calories per Slice
Standard Jiffy Mix	Mix + Egg + Milk	237
With Whole Milk	Mix + Egg + Whole Milk	182 (note: variation in sources)
With Skim Milk	Mix + Egg + Skim Milk	~170 (estimated, lower than whole milk)
With Added Butter	Mix + Egg + Milk + 2 tbsp Butter	~260 (estimated, higher than standard)
With Creamed Corn	Mix + Egg + Milk + Creamed Corn	228 (casserole variation)
With Water and Egg	Mix + Egg + Water	Lower than standard milk recipes

Tips for Modifying Your Jiffy Cornbread

If you are aiming for a lighter cornbread, there are several simple modifications you can make without sacrificing too much flavor or texture. Baking is a science, but with a little practice, you can adapt your recipes to fit your dietary needs.

Substitute Milk: Instead of whole milk, try using a lower-fat milk like skim or 1% milk. Unsweetened almond milk or other non-dairy alternatives can also be used, but may slightly alter the flavor and texture. For every cup of milk you replace, you can save a significant amount of calories.
Use a Fat Substitute: Instead of adding extra melted butter, consider using a non-stick cooking spray for the pan. If you're adding fat to the batter, a small amount of unsweetened applesauce can add moisture while significantly reducing calories and saturated fat.
Mind Your Add-ins: Be cautious with additions like cheese, bacon, or honey. While delicious, they all contribute extra calories. Consider using small amounts or opting for healthier flavor enhancers like a sprinkle of fresh chives or a dash of black pepper.
Consider Slice Size: The simplest way to control calories is to be mindful of your serving size. Cutting the pan into 12 smaller, more modest slices instead of 9 will reduce the calories per piece immediately.

The Best Way to Get an Accurate Count

The most accurate way to determine your cornbread's calorie content is to calculate it yourself. This process involves adding up the calories from each individual ingredient and then dividing that total by the number of slices you cut from the pan. This method accounts for all your specific substitutions and additions.

Calculation Steps:

Find the calories for each component: Look up the calories for the full box of Jiffy mix, the number of eggs used, and the volume of milk or other liquid. For example, an 8.5 oz box of Jiffy mix is approximately 320 calories. A large egg is roughly 70 calories. A cup of whole milk is around 149 calories.
Add up the total calories: Sum the calories from all ingredients used in your specific recipe.
Divide by the number of servings: Determine how many slices you get from your pan and divide the total calorie count by that number. This will give you the most accurate calories per slice.

For example, using the standard recipe of 1 box mix, 1 egg, and 1/3 cup of milk, and cutting into 9 slices: (320 + 70 + ~50) / 9 = ~49 calories per slice, but this does not account for the baked portion. For baked portion, based on H-E-B's data, a single portion might be around 180-200 calories depending on ingredients. Using the 237 calorie estimate for a 1/9th pan from Eat This Much is a reliable average for standard prep.

Conclusion

While a definitive single number for how many calories are in one slice of Jiffy cornbread is elusive, a standard slice prepared with milk and egg likely falls in the 200-240 calorie range. The key takeaway is that your ingredient choices and portion sizes are the most significant factors influencing the final nutritional value. By being aware of your modifications and calculating accurately, you can easily enjoy this classic side dish while staying mindful of your dietary goals. For an alternative that still uses the Jiffy mix, considering baking muffins might give you a better grasp of portion control, though even these can vary.
