The YES BAR Peanut Butter Dark Chocolate is a whole-food snack bar built on three core ingredients: peanuts, dark chocolate, and dates. There is no long list of additives to decode — what you see is largely what you get. Peanuts provide natural protein and fat, dates supply the binding sweetness along with fibre, and dark chocolate contributes that bitter-edged depth that keeps it from feeling like confectionery.
It fits neatly into the kind of routine where a mid-morning or mid-afternoon energy dip tends to hit. It works equally well as a pre-gym snack when you need something light but sustaining, or as a desk drawer alternative to the biscuit tin. Because the sweetness comes from dates rather than refined sugar, the energy release is more measured than a typical chocolate bar.
This is food first — not a supplement dressed up as a snack. The ingredient list is intentionally short, which suits anyone trying to reduce their intake of ultra-processed foods without sacrificing convenience or taste. The combination of fat, fibre, and natural sugar means it is broadly satisfying without being heavy. For those watching macros, check the packaging for the specific protein and calorie count, as this will vary by bar size.
Peanuts, Dark Chocolate, Dates

Eat straight from the wrapper as a mid-morning, mid-afternoon, or pre-exercise snack. No preparation needed. It works particularly well when you need something sustaining but light — pair with water or coffee rather than a sugary drink to keep the overall sugar load in check.
The bar is made from peanuts, dark chocolate, and dates. Check the packaging for the full ingredient breakdown and allergen information, including whether it is produced in a facility that handles other nuts or allergens.
The primary source of sweetness is dates, a whole fruit, rather than refined or added sugar. That said, dates are naturally high in sugar — this is still a sweet snack, just one where the sugar comes with fibre and micronutrients rather than in isolation.
Peanuts are a meaningful source of plant-based protein, so you can expect a reasonable contribution from this bar. Check the nutrition panel on the packaging for the exact figure, as it will depend on the bar's weight.
No — peanuts are a primary ingredient, so this bar is not suitable for anyone with a peanut allergy. If you have a tree nut allergy, check the packaging for cross-contamination warnings before consuming.
It works well as a mid-morning or mid-afternoon snack, or as a light pre-exercise option. It is not designed as a meal replacement — think of it as a convenient bridge between meals rather than a substitute for one.

Keep a few of these in my desk for the 3pm slump. Does exactly what you need — something sweet and filling without the guilt spiral of reaching for a biscuit. The dark chocolate edge stops it tasting like a kids' snack. Really pleased with it.

Bought on a whim and was pleasantly surprised. Short ingredient list, tastes good, doesn't leave me hungry again 20 mins later. Will be a regular buy.

I really like these — the peanut butter and dark chocolate combo is spot on, and I love that dates are doing the sweetening rather than a load of sugar. My only gripe is that at £2.99 it feels a touch expensive for the size of the bar. I get that clean ingredients cost more, but it just about crosses the line for an everyday snack. Still buying them, just not as often as I'd like.

Started using these before my morning runs when I don't want a full breakfast. Light enough not to sit heavy but keeps me going for the first hour. The ingredients are exactly what I want — nothing weird to read on the back of the wrapper.

Got a friend to try one and she ordered a box the same day. That's pretty much the review.

Used to reach for the heavily processed protein bars out of habit. These are a better call — the energy doesn't spike and crash, and they actually taste like real food. Peanut butter and dark chocolate is a classic combo for a reason.
