Is Kellogg's the king of cornflakes? Which? reveals the best cornflakes

20 February 2014


120 consumers have blind taste-tested 12 different brands of cornflakes to find the most delicious 

We've pitted Kellogg's cornflakes against supermarket own-brand cornflakes in our taste test to see which cornflakes are the tastiest and whether it's worth swapping to save money.

Can an own-brand label beat the taste of Kellogg's cornflakes? The Which? panel of 120 consumers have tasted 12 different cornflakes and rated each on taste, texture, appearance and aroma to find out.

Which? members can see which cornflakes come top, and the four which come very close, in our top five cornflakes brands.

Cheap cornflakes

For those worried about food budgets and anyone wanting to combat soaring food prices, we included four popular value range cornflake brands to see how they compare to the standard supermarket brands and whether they compromise on taste.  

We uncovered some surprising results; Sainsbury's Basics cornflakes (31p, 500g) were rated better than Marks & Spencer's Simply M&S cornflakes (£1.45, 500g) for taste, texture and appearance - and a box of Basics cost a lot less. 

If you want to save some cash, but don't want to sacrifice taste and crunch, then swapping from a standard brand like M&S to Sainsbury's Basics could save you around £34 a year. But none of the value brands were good enough to make it into the top five - log in or sign up for a £1 trial to see which cornflakes taste the very best.
