Muesli bars trade on a healthy reputation. Most don't earn it. We scored the major options in Australia on protein, sugar and ingredients. Results inside.

Overview
The muesli bar aisle is a tale of two products: the classic oat-and-syrup snack and the modern protein-boosted version. Our analysis across 19 popular muesli bars shows the original formula often wins on quality. Carman's Original Fruit Free Muesli Bars takes the top spot, proving that a simple, clean ingredient list can beat bars with more protein but also more processing. With a modest 8.7g of protein per 100g and just 11.6g of sugar per 100g, its strength is its simplicity, earning it a Clean Score of 7.5 with zero additives. If you're chasing a bigger protein hit, the trade-off is usually more complexity. The Uncle Tobys Protein Muesli Bar range delivers a hefty 20g of protein per 100g, but with three additives on the label. Carman's also has a higher-protein option, with its Salted Caramel Nut Butter bar leading the category for protein density at 25.9g per 100g. These are effective if protein is your only goal, but they don't match the clean profile of our top-ranked pick. For a straightforward, reliable snack you can find at Coles and Woolworths, stick with the leader. Carman's Original Fruit Free Muesli Bars is the one we'd grab first for its honest, whole-grain build without the extra stuff. It's a proper muesli bar, not just a protein delivery system held together with syrup.
The verdict
Carman's Original Fruit Free Muesli Bars takes the top spot by keeping things simple and clean. It's not trying to be a high-protein beast, instead delivering 8.7g of protein per 100g from whole oats and seeds. What really sets it apart is the ingredient list, earning it a top score for having zero additives. With sugar at a low 11.6g per 100g, it's one of the leanest options on the shelf and a clear winner for a straightforward snack. If you're chasing a bigger protein hit, the Uncle Tobys Protein Muesli Bar Double Choc is your go-to. It packs a significant 20g of protein per 100g, which translates to a solid 7g of protein per serve, more than double the protein density of our top pick. The trade-off is a slightly longer ingredient list with three additives, but for shoppers prioritising protein from an oat bar, it's the strongest performer in the category.
Rankings
- #1. Carman's Original Fruit Free Muesli Bars - Protein Score 9.6/10 · Clean Score 7.5/10 · 3.9g/serve
Protein Score 9.6/10. Carman's Original Fruit Free Muesli Bar takes the top spot by keeping things simple. The protein is a modest 8.7g per 100g, which works out to just 3.9g of protein per serve. The real win is the clean label, with zero additives listed. This is a rare find in an aisle often loaded with binders, emulsifiers and preservatives. This isn't a high-performance snack and it doesn't pretend to be. It's a straightforward whole-grain oat bar with a simple ingredient list, making it an honest lunchbox filler or morning tea snack. If you're looking for a cleaner muesli bar without a long list of numbers on the back of the pack, this is the one to grab.

It delivers a solid 20g of protein per 100g, which works out to a handy 7g of protein per serve. For a mainstream protein bar you can grab on the supermarket run, that's a seriously strong number. The profile holds up well beyond the protein. With just three additives, it lands Clean Score of 6.6/10, and its sugar content of 12.6g per 100g is well-managed for a double chocolate flavour.

While it doesn't quite hit the high notes of our number one pick, Carman's Original Fruit Free Muesli Bars, it's a reliable and easy-to-find protein bar on the supermarket shelf.

Editorial deep dive
The muesli bar aisle presents a clear choice. You can go for simple, whole-oat muesli bars that are basically baked oats and seeds, or you can pick one of the newer muesli bars that dials up the protein using isolates and crisps. Our analysis shows the simpler approach often wins on overall quality. The top spot goes to Carman's Original Fruit Free Muesli Bars, earning a Protein Score of 9.6 with a clean, zero-additive ingredient list and a sensible 8.7g of protein per 100g. Right alongside it, however, is the Uncle Tobys Protein Muesli Bar Double Choc, showing the other side of the coin. It delivers a much heavier protein hit at 20g per 100g, using soy protein crisps to get there. This is the trade-off shoppers face: the whole-food feel of a traditional oat bar versus a product engineered for a higher protein number. The Uncle Tobys muesli bars are still strong performers, but they come with a few more additives. Sugar is the other major hurdle. Many muesli bars are bound together with a lot of golden syrup or glucose, pushing sugar levels surprisingly high. Our winning Carman's muesli bar keeps it at 11.6g of sugar per 100g. Some others in the range aren't so restrained, with certain choc-coated varieties climbing past 24g of sugar per 100g. It pays to read the panel, as the gap between the leanest and the sweetest muesli bars is significant. Looking at the shelf in Coles or Woolworths, the category is mostly a contest between Carman's and Uncle Tobys. Carman's leans into classic oat, nut, and seed blends, which results in clean ingredient lists and moderate protein. Uncle Tobys targets the shopper looking for a protein boost specifically, building its muesli bars around that single metric. Neither approach is wrong, but they serve different purposes. For a straightforward, reliable lunchbox snack or morning tea bite, Carman's Original Fruit Free Muesli Bars is the one to grab first. It's a simple, honest oat bar that doesn't pretend to be a high-performance product. If you absolutely need more protein from your muesli bar, the Uncle Tobys options are there, but the Carman's muesli bar is our top pick for its clean profile and balanced nutrition.
Brand-by-brand notes
Carman's
Born in Australia, Carman's has grown into a familiar presence across the supermarket aisles. You will find all 15 protein bars we track for them stocked locally at Coles, Woolworths, or Aldi. They focus heavily on oat-based and nut-heavy snacks, aiming for that traditional pantry slot rather than the sports supplement shelf. On the numbers, the brand trails the category slightly, averaging 11.4g of protein per 100g against the wider 13.3g benchmark. Carman's Original Fruit Free Muesli Bars secures our number one spot with a Protein Score of 9.6, delivering 8.7g of protein per 100g and 11.6g of sugar per 100g. If you want the absolute most protein-dense option from the lineup, Carman's Protein Muesli Bars Salted Caramel Nut Butter hits 25.9g per 100g. On the flip side, Carman's Protein Slice Bar Choc Peanut sits as the weakest link, dragging a heavy 31.1g of sugar per 100g alongside 16.8g of protein per 100g. Next time you do a supermarket run, the leader is your best bet for a balanced macro profile. If you want a shorter ingredient list, Carman's Protein Nut Butter Peanut Butter 180g | claims the highest Clean Score of 8.9 in their range. We suggest skipping the choc-coated slices if you want to keep sugar in check, as they lean closer to standard treats than functional fuel.
Uncle Tobys
Uncle Tobys is a familiar Australian name, backed by Nestlé, producing classic oat blends fortified with soy crisps to lift their macros. You will find all 4 protein muesli bars we score here sitting on the shelves at Coles and Woolworths, making them an easy grab during the weekly supermarket run. On the numbers, this four-bar lineup easily beats the muesli bars category averages. The range delivers 20.2g of protein per 100g against a category baseline of 13.3g per 100g, while keeping sugar down to an average of 14.8g per 100g. Uncle Tobys Protein Muesli Bar Double Choc leads the brand's pack with 20g of protein per 100g and 12.6g of sugar per 100g. The weakest link is the Uncle Tobys Protein Muesli Bar Raspberry, Goji & White Choc, which keeps the 20g of protein per 100g but pushes sugar up to 17.1g per 100g. For context on the top end, Carman's Original Fruit Free Muesli Bars claims the crown for this guide with a Protein Score of 9.6. If you want a quick supermarket pickup that actually delivers on its protein claim, the Double Choc flavour is the one to grab. It keeps the sweetness in check better than the fruit-heavy options in the same range. While they do not quite match the category leader, these are highly accessible muesli bars that step up from standard sugary lunchbox fillers.

- We rank protein bars using our Protein Score, a 0-10 rating that prioritises protein density relative to calories.

A higher score indicates a bar that delivers more protein with a cleaner overall nutritional profile. We also calculate a Clean Score, which rates products on their ingredient list, flagging additives, added sugars, and artificial sweeteners.
