No, I Can’t Believe It’s Not Butter is not real butter. It’s a vegetable oil spread made primarily from water and a blend of soybean, palm kernel, and palm oils. The ingredient list contains no dairy fat, no cream, and no milk of any kind. The name is marketing wordplay, designed to suggest the taste is close enough to fool you, but the product itself is an entirely different food.
What It Actually Is
The full ingredient list for the Original version reads: water, soybean oil, palm kernel oil, palm oil, salt, soy lecithin, natural flavors, lactic acid, and added vitamins (E, D2, A, and B12), plus beta carotene for color. Water is the first ingredient, meaning it makes up the largest share by weight. Real butter, by contrast, is at least 80% milk fat churned from cream.
Technically, I Can’t Believe It’s Not Butter isn’t even margarine. Under federal standards, a product must contain at least 80% fat to be labeled margarine. Because this spread falls below that threshold, it’s classified as a “vegetable oil spread.” That’s why you’ll see that term on the packaging rather than the word margarine.
How It Compares to Butter Nutritionally
Calorie-wise, the two are surprisingly close. A tablespoon of regular butter has about 102 calories and 11.5 grams of total fat, with 7 grams of that being saturated fat. Plant-based spreads in the same category land around 100 calories and 11 grams of total fat per tablespoon, but roughly half the saturated fat (about 3.5 grams). The brand itself claims 70% less saturated fat than dairy butter.
One thing the spread offers that butter doesn’t is omega-3 ALA from its soybean oil. A single serving of the Original provides 375 milligrams, covering about 23% of the recommended daily value. It also comes fortified with vitamins A, B12, D2, and E. Butter naturally contains vitamins A and D but typically in smaller amounts, and it lacks B12 fortification.
Does It Contain Any Dairy at All?
The brand’s own FAQ confirms that both the Original and Light tubs contain no dairy ingredients. Earlier formulations of the product did include whey or other milk derivatives, which created confusion that still lingers today. The current recipe is dairy-free. If you’re vegan or lactose intolerant, the Original and Light versions are safe, though it’s always worth checking the label on newer or specialty versions since formulations can change.
How It Performs in Cooking and Baking
You can swap it onto toast or into a pan for everyday cooking without much trouble. Where it gets tricky is baking. Because the spread contains more water and less fat than butter, it changes how doughs and batters behave. Cookies tend to spread thinner and come out flatter. Frostings can turn soft or weepy instead of holding their shape. Pastries that rely on cold butter for flaky layers, like pie crust or croissants, won’t get the same lift or texture.
The Light version is especially poor for cooking. It has even more water and less fat, and it contains gelatin, which causes it to burn quickly in a hot pan. If you’re frying eggs or sautéing vegetables, stick with the Original or use actual cooking oil. For baking recipes where butter is a structural ingredient, not just a flavoring, real butter will give better results.
Is the Spread Healthier Than Butter?
The main health advantage comes down to the type of fat. Butter is high in saturated fat, which raises cholesterol and contributes to inflammation. Plant-based oils contain more unsaturated fat, which has the opposite effect on cardiovascular health. A large study published by Harvard Health found that participants with the highest butter intake were 15% more likely to die over the course of the study compared to those who ate the least. Replacing butter with plant-based oil was linked to up to a 17% lower risk of premature death from cancer or cardiovascular disease. Swapping even a small amount, less than a tablespoon per day, showed measurable benefit.
That said, “healthier than butter” doesn’t mean health food. The spread still contains palm kernel and palm oils, which are higher in saturated fat than other plant oils like olive or canola. It’s a processed product, and whole food fat sources like olive oil, nuts, and avocado remain better choices when you have the option. The spread’s real niche is as a convenient, lower-saturated-fat alternative for people who want something that tastes and behaves like butter on bread or in simple cooking.
Original vs. Light
The Original has more fat and delivers 23% of your daily omega-3 ALA per serving. The Light version cuts calories and fat further but drops the omega-3 content to about 10% of the daily value. Both are dairy-free. The Light version’s higher water content makes it less versatile in the kitchen, particularly for frying or any recipe that depends on fat for structure. For most people, the Original is the more practical choice unless you’re specifically trying to reduce fat intake on toast or steamed vegetables.
