Standard Kellogg’s Corn Flakes are not gluten-free — they contain barley malt flavoring.
No. Standard Kellogg’s Corn Flakes are made from corn, sugar, salt, and malt flavoring — and the malt flavoring is derived from barley, a gluten-containing grain. The corn base is gluten-free, but the barley malt makes the finished cereal not gluten-free, and it is not labeled gluten-free. For gluten-free corn flakes, choose a cereal specifically labeled gluten-free with no malt flavoring.
Standard corn flakes are not gluten-free, and this is one of the most common surprises on a gluten-free diet. They’re corn — that part is fine. The problem is the malt flavoring, which is made from barley. Barley is a gluten grain, so the box is out.
Why Standard Corn Flakes Aren’t Gluten-Free
Standard Kellogg’s Corn Flakes are made from milled corn, sugar, salt, and malt flavoring. Per FDA labeling rules, the gluten-containing grains are wheat, barley, rye, and their hybrids. The malt flavoring in corn flakes is derived from barley — a gluten grain — so the cereal is not gluten-free and is not labeled gluten-free.
Cross-Contamination Risk
Manufacturing
High
- Not cross-contact — barley malt flavoring is an intentional ingredient.
- Barley is a gluten-containing grain.
- Standard corn flakes are not labeled gluten-free.
Recipes / Coatings
High
- Corn-flake “crispy” chicken coating inherits the barley malt.
- No-bake recipes/crusts with corn flakes are not gluten-free.
- Buffet cereal dispensers — assume standard (malted) corn flakes.
Home
High
- Standard corn flakes are not gluten-free.
- Only a specifically labeled gluten-free corn flake is safe.
Corn Flakes — GF Status
- Standard Kellogg’s Corn Flakes — NOT gluten-free (barley malt flavoring)
- Other corn flakes with “malt flavoring” — NOT gluten-free
- Corn flakes specifically labeled “gluten-free” — gluten-free (no barley malt)
- Certified gluten-free corn flake brands — gluten-free (verify the box)
- Corn-flake-coated or no-bake corn-flake recipes — NOT gluten-free (unless using GF flakes)
What to Look For — Or Avoid
- An explicit “gluten-free” label on the corn flakes box
- Ingredient list with no malt / malt flavoring / malt extract
- “Contains:” statement with no barley or wheat
- Standard Kellogg’s Corn Flakes (barley malt flavoring)
- “Malt flavoring” / “malt extract” anywhere in the ingredients
- Assuming a corn cereal is gluten-free because it’s corn
Frequently Asked Questions
Are corn flakes gluten-free?
Standard Kellogg’s Corn Flakes are not. They are made from corn, sugar, salt, and malt flavoring, and the malt flavoring is derived from barley — a gluten-containing grain. The cereal is not labeled gluten-free.
If corn flakes are corn, why aren’t they gluten-free?
The corn base is gluten-free, but the malt flavoring used as a sweetener/flavor is barley-derived. Barley is a gluten grain, so the finished cereal is not gluten-free even though the main ingredient is corn.
Is malt flavoring gluten?
Yes, in practice. “Malt,” “malt flavoring,” and “malt extract” are derived from barley, a gluten-containing grain. Any cereal listing malt flavoring — including standard corn flakes and Rice Krispies — is not gluten-free.
Is there a gluten-free corn flake?
Yes — some brands make a corn flake specifically labeled gluten-free with no barley malt flavoring. You must look for the explicit “gluten-free” label; standard Kellogg’s Corn Flakes are not it.
Is corn-flake-crusted chicken gluten-free?
Not if it uses standard corn flakes. The barley malt in standard corn flakes carries through to any coating or no-bake recipe. Use a specifically labeled gluten-free corn flake to make the dish gluten-free.
Can people with celiac disease eat standard corn flakes?
No. Standard Kellogg’s Corn Flakes contain barley malt flavoring and are not gluten-free or safe for celiac disease. Choose a corn flake (or other cereal) specifically labeled gluten-free instead.
