The Trek Salted Caramel protein flapjack is one of the tastiest grab-and-go vegan snacks we've tried, packing 9g of plant-based protein into a chewy, sweet-and-salty oat bar. I'll start with a disclaimer: I'm a huge fan of salted caramel. With cookies, chocolate or protein powders, I'll always favour the salted caramel option, so I've tried hard to keep my tastebuds honest in this review.
After buying a box of 16 Trek Salted Caramel bars, our team got stuck in over a two-week period and used them for different reasons. Some had them as a pre-workout snack, others as a stand-in for a missed breakfast. Here's our honest take on the taste, quality and value for money.
Pros
- Genuine sweet-and-salty flavour that isn't sickly
- Chewy, satisfying oat texture
- 9.3g of plant-based protein per bar
- Vegan, gluten-free and made with natural ingredients
- Very filling, great before a workout or as a breakfast stand-in
Cons
- Sugar content is on the high side at 11.6g per bar
- Moreish enough that one box doesn't last long
Trek Salted Caramel overview
Trek make a wide range of protein-filled nut bars, flapjacks and energy bars, all of which are 100% vegan, gluten-free and made with natural ingredients. Every bar carries a minimum of 9g of protein, which makes them a strong grab-and-go choice for anyone after a healthy, high-protein snack.
The Trek Salted Caramel protein flapjacks are:
- Wheat and gluten-free
- Made with natural ingredients
- Packed with plant-based protein
- Vegan friendly
- Free from trans fats
- GM free
Taste
I was initially worried these flapjacks would be sickly sweet. Luckily, I had nothing to worry about.
The bars have a sweet, chewy texture with a good balance between the oat flavour and the caramel. The hints of sea salt really shine through and make a big difference. It would probably taste a little plain if it were just caramel. As a salted caramel devotee, I found them very addictive. They're also genuinely filling, which makes them ideal for days when you've skipped breakfast or need something just before a workout.
The oats deserve a mention too: chewy, gooey goodness, and that's all you need to know.
Nutrition
Trek is one of the big names in healthy snacking, so you're right to expect a well-balanced nutritional profile. Here's the full breakdown for the Trek Salted Caramel protein flapjack.
| Energy | 223 kcal |
|---|---|
| Fat | 10.2g (of which saturates 4.8g) |
| Carbohydrate | 22.9g (of which sugars 11.6g) |
| Fibre | 1.9g |
| Protein | 9.3g |
| Salt | 0.58g |
The protein content is what really shines through. Getting 9.3g of protein per bar is a very good amount for such an affordable product.
Watch the sugar
At 11.6g of sugar per bar, the more health-conscious may want to keep an eye on these. On balance they're still a winner against other healthy flapjacks in a similar price bracket, just enjoy them as part of a balanced diet rather than by the boxful.
Final verdict
Trek keeps experimenting and innovating with its range of protein-packed bars, and the Salted Caramel flapjack is no different. It's an absolute winner on flavour and texture, with a great nutritional profile and very few negatives. The one that jumps out is the sugar content, which we'd love to see lowered, but it's not a deal-breaker.
