Granola, Muesli and Flake Cereal Compared

Published Updated 15 min read

Bestsellers for Granola & Muesli

Granola is rolled oats baked with sweeteners, oil, nuts and fruit into crunchy clusters, muesli is an unbaked loose mix of grains, fruit, nuts and seeds, and flake cereal is cooked grain pressed thin and toasted. Here is what we carry on our shelves by type and how to compare Nutrition Facts labels.

Because these cereals are processed differently, they vary in texture, how they absorb milk, and how much food fits in a cup.

Granola vs Muesli vs Corn Flakes: The Short Answer

Comparing a 1-cup bowl of each cereal shows what label servings hide. One cup of our Open Nature Nut Honey Granola has 480 calories and 22 g added sugars, while 1 cup of Bob's Red Mill Old Country Style Muesli has 560 calories and 0 g added sugars. One cup of our Signature SELECT Corn Flakes has 100 calories and 2 g added sugars, meaning a cup of granola delivers nearly five times the calories and eleven times the added sugar of corn flakes.

Pick corn flakes when you want a light, crisp bowl with a larger portion. Choose an unsweetened muesli such as Bob's Red Mill for whole grains, nuts and dried fruit with no added sugar. Use granola as a crunchy yogurt topping or pour a smaller half-cup serving with milk.

What Granola Is Made Of

To make granola, rolled oats are mixed with sweeteners, dried fruit, nuts and oil, spread onto a pan, baked and broken into chunks. While the differences among steel-cut, rolled and instant oats come from how much the oat groat is cut, steamed or flattened, rolled oats give granola its flat base. When oats and nuts are tossed with liquid sweeteners and oil, every flake gets coated. As the pan bakes and cools, the sugars concentrate and harden into a glaze that binds the oats, seeds and nuts into crunchy clusters.

The ingredient list on our Open Nature Nut Honey Granola starts with whole rolled oats, cane sugar, whole rolled wheat and expeller pressed canola oil. Ingredients are listed in descending order by weight, so seeing cane sugar and canola oil in the first four spots tells you the glaze is a big part of the recipe.

Our O Organics Oats & Honey Granola starts with organic whole rolled oats, organic cane sugar and organic crisp brown rice, and later lists canola oil, molasses and honey. The puffed rice adds lightness to the clusters, while the sugars and honey form the coating. A ⅔-cup serving has 290 calories, 5 g fiber, 12 g total sugars and 11 g added sugars, meaning only 1 gram of sugar occurs naturally in the oats and brown rice.

What Muesli Is and How to Eat It

Muesli is an unbaked, loose mixture of grains, dried fruit, nuts and seeds with no sugar glaze holding it in clusters. Bob's Red Mill Old Country Style Muesli blends whole grain wheat, rolled oats, raisins, almonds and walnuts with dates, sunflower seeds, whole grain rye, barley, whole grain triticale and flaxseed, without sugar, honey, syrup or oil. Its sweetness comes from raisins and dates, and its fats come from the seeds, nuts and grains. We also carry Bob's Red Mill Fruit & Seed Muesli and Alpen Swiss Style Muesli No Sugar Added.

Muesli is safe to eat raw because commercial rolled oats are steamed before they are flattened. Steaming inactivates the natural enzymes in whole oats that would otherwise break down fats and turn the oat oils rancid.

Pour cold milk over muesli and eat it immediately for chewy grains and crisp nuts, or mix ¼ cup muesli with ½ cup yogurt, milk or fruit juice for 5 to 10 minutes to soften. You can also soak it overnight with yogurt and grated apple so dense grains like rye, barley and triticale hydrate into a creamy bowl.

Keep soaked muesli refrigerated overnight, as North Carolina Cooperative Extension notes that room-temperature liquid lets Bacillus cereus bacteria on grains multiply and make toxins that cause vomiting, diarrhea and stomach pains. For a hot bowl, cook muesli like oatmeal with water on the stove or water or milk in the microwave.

Flake Cereals, From Corn Flakes to Bran Flakes

Flake cereals are made from cooked grain pressed thin between rollers and toasted. Because thin toasted flakes trap plenty of air in a cup, a serving fills much more of your bowl.

Our own Signature SELECT Corn Flakes lists milled corn, sugar, salt and molasses as its first four ingredients and gives you a 1½-cup serving. We also carry our Signature SELECT Bran Flakes and Nature's Path Organic Heritage Flakes, which blends wheat, oats, spelt, barley, millet and quinoa into a sturdy flake that stays crisp in milk.

If you want flakes and granola in one bowl, try our Signature SELECT Raisin Bran with Crunchy Granola or our Signature SELECT Oats & More with Almonds.

Read the Serving Size Before Comparing Labels

The six labels in our table use servings from ¼ cup to 1½ cups, so check the serving line before comparing calories, fiber or sugars. Seeing 140 calories on one box and 150 calories on another looks similar until you notice the 140-calorie muesli is ¼ cup and the 150-calorie corn flakes fill 1½ cups, a six-fold difference in volume. Serving sizes are set by weight, so a cup of dense granola holds far more food than a cup of light flakes.

Bob's Red Mill Old Country Style Muesli is the only cereal in our table with 0 g added sugars, though its ¼-cup serving is also the smallest by volume. By contrast, our Open Nature Maple Pecan Granola lists 15 g total sugars and 15 g added sugars for ⅔ cup. Total sugars include natural fruit sugars from raisins and dates, while the indented added sugars line counts sweeteners put in during processing, such as cane sugar, honey, molasses and syrups. The FDA Daily Value for added sugars is 50 grams based on a 2,000-calorie diet, so 15 grams of added sugars in our Maple Pecan Granola equal 30 percent of the Daily Value, while the muesli has 0 percent.

Measuring out a full 1-cup bowl of each cereal shows how these numbers shift. Pouring 1 cup of Bob's Red Mill muesli quadruples its ¼-cup serving to 560 calories, 16 g fiber, 20 g total sugars and 0 g added sugars. Pouring 1 cup of our Open Nature Nut Honey Granola doubles its ½-cup serving to 480 calories, 8 g fiber, 24 g total sugars and 22 g added sugars, or 44 percent of the Daily Value. Meanwhile, 1 cup of Nature's Path Heritage Flakes matches its label at 160 calories, 7 g fiber, 5 g total sugars and 5 g added sugars, or 10 percent of the Daily Value, and 1 cup of our Signature SELECT Corn Flakes drops from its 1½-cup label to 100 calories and 2 g added sugars, or 4 percent of the Daily Value.

Common Questions About Granola and Muesli

What is the difference between granola and muesli?

Granola is made by coating rolled oats, nuts and fruit with oil and sweeteners and baking them into crunchy clusters. Muesli is an unbaked, loose mix of rolled grains, dried fruit, nuts and seeds with no glaze.

Can you eat muesli without cooking it?

Yes, commercial rolled oats are steamed and flattened during processing, which inactivates enzymes and makes muesli safe to eat raw. Eat it cold with milk, soak ¼ cup muesli in ½ cup milk, yogurt or juice for 5 to 10 minutes, or refrigerate it overnight with yogurt and grated apple.

Is granola a cereal?

Yes, granola is a ready-to-eat cereal. It sits in our cereal aisle, in the granola and muesli section.

How much granola is a serving?

Check the Nutrition Facts panel on the package, as the granolas we compare here list either ½ cup or ⅔ cup per serving. Because baked clusters with nuts and fruit are heavy, a serving fills less of a cup than airy flakes.

What is the difference between granola and oatmeal?

Both can start with rolled oats, but granola is baked with oil and sweeteners into crisp clusters. Oatmeal is made by cooking rolled, steel-cut or instant oats in water or milk on the stove or in the microwave for a warm, soft bowl.

How should opened granola and muesli be stored?

The USDA FoodKeeper lists opened ready-to-eat cereal at about 2 to 3 months in the pantry for best quality. Clemson University Cooperative Extension recommends storing opened cereal in an airtight container in a cool, dry pantry to keep out moisture, dust and insects and protect the oils in the oats and nuts.

Why do flake cereals have bigger cup servings?

Nutrition Facts serving sizes are set by weight rather than volume. Because airy flakes weigh much less per cup than dense granola or muesli, the same weight fills much more of a cup.

What food group is granola?

Granola is mostly rolled oats, so it counts in the grains group on USDA MyPlate. Its nuts and seeds belong to the protein foods group.

Can muesli upset your stomach?

Muesli is high in fiber, and going from a low-fiber breakfast to a full bowl at once can cause gas or bloating, so start with a smaller serving and drink water. Soaked muesli left out of the fridge can grow Bacillus cereus bacteria that cause vomiting and diarrhea, so keep it refrigerated.

Is muesli healthier than granola?

Compare labels: the Bob's Red Mill muesli in our table has 0 g added sugars and is unbaked with no oil coating, while the granolas have 11 to 15 g added sugars per serving. Both are dense, so portion matters.
