Comparison criteria and trade-offs
Among records with exact values, Fitbakes Cookies & Cream Crunch (19g) has the lowest recorded calories per bar (63 kcal), while Born Winner Waffle Chocolate (85g) has the highest recorded protein per bar (30.6g). A smaller portion can explain a lower calorie figure; compare serving weight and the per-100g values before deciding.
This selection includes the matching published records in the Which Bar catalogue, not an exhaustive market survey. Missing, qualified and disputed values are excluded from the ranges above. Ingredient, allergen and dietary evidence is available on each product page. These are label comparisons, not hands-on taste or fullness rankings. Recipes and pack prices can change; check the seller and current wrapper.
