Kettle Corn Nutrition: 140 Calories per 28 g in Two Label Examples

For a 28 g serving—roughly 1 ounce—both kettle corn products below list 140 calories. They provide 18–19 g carbohydrate, 7–8 g fat, 2 g fiber and 1 g protein. That is a useful packaged-food reference, not a universal value for every brand, microwave bag or fairground recipe.

The serving weight matters: these two products assign different cup volumes to the same 28 g portion.

Nutrition facts for two packaged kettle corns

These are U.S. label examples checked October 9, 2026. Angie’s figures come from a retailer’s label transcription; SKINNYPOP’s come from the manufacturer’s product page.

Nutrition per labeled serving	Angie’s BOOMCHICKAPOP Sweet & Salty	SKINNYPOP Sweet & Salty
Serving weight	28 g	28 g
Approximate volume	2 cups	2½ cups
Calories	140	140
Total carbohydrate	18 g	19 g
Total fat	8 g	7 g
Saturated fat	0.5 g	0.5 g
Protein	1 g	1 g
Dietary fiber	2 g	2 g
Total sugars	8 g	8 g
Added sugars	8 g	7 g
Sodium	110 mg	110 mg

Added sugars are part of total sugars, not an extra amount to add on. For example, SKINNYPOP’s 8 g total sugars already includes its 7 g added sugars.

Both examples supply some fiber but little protein. SKINNYPOP identifies its popcorn as whole grain, yet its kettle corn still contains added sugar and oil. Read those features together rather than treating “whole grain” as the entire nutritional assessment.

Calories per cup versus calories per gram

Angie’s advertises 70 calories per cup. Dividing SKINNYPOP’s 140-calorie serving by 2½ cups gives 56 calories per cup, calculated from its label.

By weight, however, both labels give the same calorie estimate: 5 calories per gram. Their cup-to-weight conversions differ.

For either of these specific products:

Weighed portion	Calculated calories
14 g	70
28 g	140
42 g	210
56 g	280

These are scaled label estimates, not separately measured portions. Use your own package if its numbers differ.

Is kettle corn higher-calorie than regular popcorn?

Not necessarily. At the same 28 g weight, SKINNYPOP Original lists 150 calories, 10 g fat, 15 g carbohydrate and 0 g added sugar. Its Sweet & Salty kettle corn lists 140 calories, less fat and more carbohydrate, including added sugar.

In this brand-specific comparison, the sweeter product lists slightly fewer calories. “Regular popcorn” is therefore not a reliable calorie shortcut: preparation and oil content matter, and this comparison is with packaged oil-popped popcorn—not plain air-popped corn.

How to log your actual portion

For packaged kettle corn, use:

Portion calories = grams eaten ÷ label serving grams × label calories

Scale carbs, fat, protein and added sugars the same way. If you eat the whole bag, check servings per container rather than assuming the front-of-pack calorie number covers everything. The same arithmetic is explained in our whole-bag calorie guide.

For homemade kettle corn, total the calories from the kernels, oil and sugar used, then divide by the finished edible batch weight to estimate calories per gram. This assumes those ingredients end up in the edible batch; discarded kernels or oil and sugar left in the pan can make that estimate too high.

A fairground portion without a label or recipe cannot be pinned to these packaged examples; weighing it helps define the portion, but the unknown sugar and oil amounts remain.
