Classic Cereals Compared

Published 2026-10-27

Corn Flakes, Rice Krispies and Special K have been pantry staples for generations. They are all lightly sweetened, which makes them popular with adults and handy as cooking ingredients, but each has its own grain, texture and best use. This comparison helps you decide which box to keep on the shelf, and how to use the last third of the box before it goes stale.

Corn Flakes

Corn Flakes are toasted flakes of milled corn with a simple, mildly sweet flavor. They are crisp but soften fairly quickly in milk, so eat them promptly if you like crunch. Crushed Corn Flakes are a classic coating for oven-fried chicken and a topping for casseroles. Note that many corn flake cereals include malt flavoring from barley, so they are usually not gluten free.

Rice Krispies

Rice Krispies are toasted crispy rice known for their 'snap, crackle, pop' when milk is poured on. They are light and mild, which makes them a good choice for younger children and a must-have ingredient for no-bake marshmallow treats. Like corn flakes, many crispy rice cereals contain malt flavoring, so check the label if you need a gluten-free option.

Special K

Special K Original is made from rice and wheat into thin, crisp flakes. It is often chosen by adults who want a light, lightly sweetened cereal and like to add their own fruit. Because it contains wheat, it is not gluten free. Special K comes in many flavors with fruit or clusters, but the Original is the most versatile.

Which to choose

If you want a simple, cheap everyday cereal that also works in cooking, choose Corn Flakes. If you have kids or plan to make cereal treats, choose Rice Krispies. If you like a light, slightly heartier flake for yourself, choose Special K. All three are great bases for adding berries, bananas or a sprinkle of nuts. Keep opened boxes tightly closed, because light flakes and crisp rice lose their crunch quickly in humid kitchens.
