Kellogg’s Crunchy Nut vs supermarket honey nut cornflakes

We pitted Kellogg’s Crunchy Nut cornflakes against cheaper supermarket own brands in a blind taste test to find out if it’s worth paying more for a big-brand cereal

Combining sweet honey, chopped peanuts and crunchy cornflakes, Kellogg’s Crunchy Nut is one of the most popular breakfast cereals in the UK.

But with many supermarkets offering cheaper own-brand honey nut cornflakes - often for less than half the price - opting for a supermarket cereal could lead to significant savings on your shopping bill over time.

In August 2021, we tested Kellogg’s Crunchy Nut alongside seven supermarket honey nut cornflakes from the likes of Aldi, Asda and Tesco.

We uncovered some bargain breakfast cereals with a lovely, nutty flavour and perfect crunch – but others were less impressive. Keep reading to find out which cereals topped our taste test.

Best honey nut cornflakes

Aldi and Morrisons both scooped Best Buys, beating big brand Kellogg’s. 

Most of the other supermarket own labels we tested also scored well, so you don’t need to spend a lot to get great-tasting cornflakes.

All prices correct as of September 2021.

Best Buys: Aldi and Morrisons

Aldi Harvest Morn Honey Nut Crunchy Cornflakes and Morrisons Honey Nut Corn Flakes

Best Buy and Great Value: Aldi Harvest Morn Honey Nut Crunchy Cornflake - 76% (17p per 100g)

Best Buy: Morrisons Honey Nut Corn Flakes - 76% (30p per 100g)

Aldi and Morrisons honey nut offerings topped our taste test - their well-balanced honey and nut flavours, plus the satisfying level of crunch proved a hit with our tasters.

They’re both good value for money, too, offering considerable savings compared with Kellogg’s. Aldi, which is the joint-cheapest on test, costs just 17p per 100g – less than three times the price of Kellogg’s at 60p per 100g.

Opting for Aldi or Morrisons will also get you a healthier breakfast. Both cereals contain around 20% less sugar compared to Kellogg’s - however, like most of the honey nut cereals we tested, they’re still classed as high in sugar.

If you're more of a Tesco shopper, its version also beat Kellogg's (75%, 20p per 100g), so is another good option, although it just missed out on being a Best Buy.

Morrisons Honey Nut Corn Flakes are available from Morrisons

Kellogg’s Crunchy Nut - 73% (60p per 100g)

It's still a tasty option, but Kellogg’s didn’t quite match up to rival cereals from Aldi and Morrisons on flavour according to our tasters despite a higher sugar content. 

The all-important nuttiness was lacking for some and more than half thought it didn’t have enough nut pieces. But it lived up to its name on texture, with most finding it to have just the right level of crunch.

Kellogg's Crunchy Nut costs more than twice as much as most rivals, many of whom score similarly - or higher. It’s also the most sugary cereal we tested, containing 35g of sugar per 100g. So, while it's tasty, you can save money and cut sugar by picking a supermarket option.

Kellogg’s Crunchy Nut cereal is available from Asda, Co-op, Morrisons, Iceland, Ocado, Sainsbury’s, Tesco and Waitrose

How do other supermarket honey nut cornflakes fare?

Tesco Honey Nut Cornflakes,  M&S Honey Nut Cornflakes, Lidl Crownfield Honey Nut Flakes, Asda Honey Nut Corn Flakes, Honey Nut Cornflakes by Sainsbury's

Tesco Honey Nut Cornflakes - 75% (20p per 100g) | M&S Honey Nut Cornflakes - 73% (30p per 100g) | Lidl Crownfield Honey Nut Flakes - 73% (17p per 100g) | Asda Honey Nut Corn Flakes - 72% (19p per 100g) | Honey Nut Cornflakes by Sainsbury's - 66% (20p per 100g)

Our results show that wherever you shop, it’s worth giving a supermarket own-label option a go before reaching for the pricier big brand.

While Aldi and Morrisons were the standouts, the rest of the supermarket cereals we tested generally put in a strong showing overall. Tesco, in particular, impressed across the board, leading it to claim the runner-up spot. M&S and Lidl both scored 73%, tying neck and neck with Kellogg’s.

Sainsburys shoppers might want to keep an open mind though. Although Sainsbury's honey nut flakes didn’t score too badly overall, they fell slightly behind the crowd, with a score in the mid-60s. These flakes disappointed some with their flavour, which 45% of tasters said was too sweet - and many found lacking in nuttiness. Our panel also thought they looked less appealing compared to the other cereals they tasted.

Are honey nut cornflakes healthy?

Person eating cornflakes

They may be a tasty start to the day (or evening snack - just me?), but it's worth bearing in mind that all the honey nut cornflakes we reviewed were pretty high in sugar.

As Shefalee Loth, Which? nutrition expert, explains: ‘After maize, the main ingredient in all these cereals is sugar - and they all also contain other forms of "hidden" sugar such as honey, molasses and syrups.

'Some have vitamin D added in, although this is a relatively small amount of your daily requirements. Kellogg's Crunchy Nut contains 25% of the recommended daily dose in a 30g portion, while others contain only 15% (it's worth noting that previous Which? research revealed that most people actually eat much bigger cereal portions than the recommended amount).

'Kellogg's Crunchy Nut contains the most sugar of the honey nut cornflakes tested at 35g of sugar per 100g. That's nearly three teaspoons of sugar per 30g portion (see note above regarding portion size). 

'Supermarket own-brand versions are better - most contain around 28g of sugar per 100g, 20% less than Kellogg's. But that's still high - they all get a red traffic light (high rating) for sugar, except for Lidl's version - which has a medium sugar rating.'

Which breakfast cereals have the most sugar?

Kellogg’s Crunchy Nut packs in a lot of sugar, but how do other options measure up?

We compared the amount of sugar in popular branded breakfast cereals* and ranked them from most to least sugar per 100g and found there was wide variation, so it pays to pay attention to what you pick up from the cereal shelf.

Kellogg's Crunchy Nut topped the table, but Kellogg's Krave Milk Chocolate isn't far behind. Both are classed as high in sugar as they contain more than 22.5g per 100g. 

CerealSugar per 100g
Kellogg's Crunchy Nut35g
Kellogg's Krave Milk Chocolate28g
Cheerios Multigrain17.6g
Kellogg's Coco Pops17g
Kellogg's Special K15g
Nestlé Shreddies13g
Kellogg's Corn Flakes8g

*Most popular ready to eat cereals from The Grocer's Top Products Survey 2020 based on sales data from Nielsen Scantrack.

Most of the most popular cereals we looked at have a medium sugar rating, including Kellogg’s Coco Pops, Kellogg’s Special K and Kellogg’s Rice Krispies.

If you’re looking to switch to a less sugary cereal, Weetabix and Nestlé Shredded Wheat are good options, as both are classed as low in sugar.

Weaning yourself on to plain cornflakes (perhaps for weekdays) would also be a good switch as these contain a fraction of the sugar of the crunchy nut versions.

How to recycle cereal packaging

Cereal boxes

Cardboard cereal boxes can usually go in your household recycling bin.

The inner plastic bags can’t go in your household recycling bin, but you may be able to recycle them along with carrier bags at some supermarkets, if they have soft plastic bins.

How we taste-tested honey nut cornflakes

The cereals were served with semi-skimmed milk and assessed by a large panel of consumers who regularly buy and consume this type of product.

The make-up of the panel broadly represents the demographic profile of adults in the UK. 

Each cereal was assessed by 67 people.

The panellists rated the taste, texture, aroma and appearance of each product, and told us what they liked and disliked about each one. 

The taste test was blind, so the panellists didn’t know which brand they were trying. The order they sampled the cereals was fully rotated to avoid any bias. 

Each panellist had a private booth so they couldn’t discuss what they were tasting or be influenced by others.

The overall score is based on:

  • 50% taste
  • 20% texture
  • 20% aroma
  • 10% appearance
