For a cereal bar with commuter coffee, compare the calories in the portion you will actually eat, then check its sugars, fibre, protein and allergens. The smaller examples in the supplied UK product information are Kellogg’s Special K Red Berry at 104 kcal per 27 g bar and Graze Cocoa Vanilla Oat Boost at 116 kcal per 30 g serving; the cited Nature Valley and TREK protein bars provide larger portions and more calories, which may suit a different kind of snack break.
If the bar is an accompaniment rather than breakfast, compare the calories and sugars in one bar. Kellogg’s UK lists 104 kcal for a Special K Red Berry Bar; Tesco Groceries lists 116 kcal per Graze Cocoa Vanilla Oat Boost.
You may prefer to compare protein and fibre as well as portion calories. Nature Valley UK lists 10.2 g protein and 4.5 g fibre in its 197 kcal Chocolate & Coffee Protein bar; Ocado lists 10 g protein and 219 kcal for a TREK Original Oat Protein Flapjack. Neither figure establishes how long a bar will keep you full.
Read the allergen and dietary statements for the exact flavour and pack. The cited products differ in their milk, soya, peanut and cereal ingredients, and a vegan label does not remove the need to check allergen warnings.
Start with the portion you would eat alongside coffee. Use the rest of the nutrition panel and the allergen statement to decide whether that particular bar fits the occasion.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Check kcal for the number of bars you will eat and the stated serving weight. Nature Valley UK declares its Crunchy Variety serving as two bars, weighing 42 g and providing 196 kcal. | I’m having a bar with coffee, not replacing a meal. A two-bar serving needs comparing with other full portions, not with a single bar. |
| Sugars | Compare the ‘of which sugars’ figure for each portion. Tesco Groceries lists 2.7 g for a 30 g Graze Cocoa Vanilla Oat Boost; Kellogg’s UK lists 7.6 g for a 27 g Special K Red Berry Bar. | If my coffee is sweetened, I also want to know what the accompanying bar contributes. |
| Protein and fibre | Read grams per bar alongside kcal and weight. Nature Valley UK lists 10.2 g protein and 4.5 g fibre per 40 g Chocolate & Coffee Protein bar, with 197 kcal. | When there’s a long gap before my next meal, I may choose a larger bar for its stated protein and fibre amounts rather than select by calories alone. |
| Allergens and diet | Read the exact pack’s ingredients, ‘may contain’ wording and any vegan or gluten-free statement. Do not apply one flavour’s label to another. | I need a bar whose current ingredient and allergen information fits my requirements, even when its portion calories look suitable. |
A 27 g bar, a 50 g flapjack and a declared serving of two bars are different amounts to eat.
Compare kcal for your intended portion first; use per-100-g figures as a separate comparison of products at the same weight.
Nature Valley UK lists 197 kcal per Chocolate & Coffee Protein bar, while Ocado lists 219 kcal per TREK Original Oat Protein Flapjack. Both portions are larger than the cited 27–30 g snack-bar examples.
If you want a small accompaniment to coffee, compare the full portion calories before choosing a protein-led format.
Bars with those ingredients can have different sugar amounts: Tesco Groceries lists 2.7 g per Graze Cocoa Vanilla Oat Boost, while Kellogg’s UK lists 7.6 g per Special K Red Berry Bar.
Read ‘of which sugars’ for the portion you will eat, particularly if you also sweeten your coffee.
Alpen’s UK FAQ lists Alpen Light Chocolate & Orange among products no longer made. An older nutrition listing may therefore refer to a product you cannot identify on a current pack.
Check the exact product and its current nutrition label before using an older calorie figure.
These examples describe particular products or ranges, not the nutrition or availability of every bar from a brand.
Its Cocoa Vanilla Oat Boost is a 30 g flapjack listed by Tesco Groceries at 116 kcal per serving.
Kellogg’s UK lists its Special K Red Berry Bar at 104 kcal per 27 g bar.
Its UK range includes Crunchy and Protein bars, which use different portion formats.
The Original Oat Protein Flapjack is a 50 g option for someone considering a larger snack.
Tesco Groceries lists fruit-and-nut bar formats, including Almond & Cranberry with Pomegranate & Honey.
Older Alpen Light bar listings may come up when comparing small cereal bars.
These oat squares, cereal snack bars and protein bars are options to examine for a commuter coffee break. Their flavours and pack sizes are identifiable here; compare each exact pack’s nutrition and allergen label before deciding how it fits your intended portion.

For a coffee break built around a 30 g oat square, check the pack’s kcal and sugars for one square, then its allergen statement. Do not use nutrition figures for Graze Cocoa Vanilla Oat Boost as figures for these Protein Bites.
No image available
If you are considering a 40 g protein bar rather than a smaller coffee accompaniment, compare its per-bar kcal, protein and fibre. This Peanut & Chocolate variant is not the Chocolate & Coffee bar used in the earlier nutrition examples; check its own label, including the peanut allergen information.

The 21.5 g bar size is relevant if you want a small portion with coffee. Check this Dark Chocolate variant’s own kcal and sugars per bar rather than applying figures for Special K Red Berry.

This Cherry Bakewell oat bar comes in a 30 g portion. Compare its own per-bar kcal and sugars with other 30 g options, and read its allergen statement; the cited Cocoa Vanilla figures describe a different flavour.
No image available
For a lemon-and-blueberry oat bar alongside coffee, use the 30 g portion to compare this flavour’s kcal and sugars with other bars. Check its current dietary and allergen statements separately from those of other Graze products.
Compare kcal for the amount you will actually eat rather than treating the phrase as a fixed category. Kellogg’s UK lists 104 kcal for a 27 g Special K Red Berry Bar, while Tesco Groceries lists 116 kcal for a 30 g Graze Cocoa Vanilla Oat Boost; their smaller portions matter when comparing them with larger bars.
Yes—read both figures for the same eating occasion. Tesco Groceries lists 2.7 g sugars per 30 g Graze Cocoa Vanilla Oat Boost, while Kellogg’s UK lists 7.6 g per 27 g Special K Red Berry Bar. Include anything you add to your coffee when considering the whole break.
Its name alone cannot tell you that. Check the exact bar’s portion calories, protein and fibre when choosing a snack for a longer gap before your next meal: Nature Valley UK lists 10.2 g protein and 4.5 g fibre for its 197 kcal Chocolate & Coffee Protein bar, while Ocado lists 10 g protein and 219 kcal for a TREK Original Oat Protein Flapjack.
