Few treats are as universally loved in the UK as a caramel-filled chocolate bar. Sweet, gooey caramel wrapped in smooth chocolate is simple in concept but difficult to execute perfectly. Some bars nail the balance, while others drown the chocolate or overwhelm with sticky sweetness.
We tested popular caramel bars across UK supermarkets and corner shops, evaluating them on caramel quality, chocolate taste, texture, and overall indulgence.
Caramel Quality: Smooth, Gooey, or Grainy?
The caramel makes or breaks the bar.
- Smooth & flowing caramel provides indulgence and contrast against chocolate.
- Grainy or overly thick caramel feels cheap and cloying.
- Flavour depth also matters — hints of butter and toffee richness beat plain sugar sweetness.
Chocolate Taste: The Outer Shell
The chocolate coating should complement, not compete with, the caramel.
- Creamy milk chocolate is the classic pairing.
- Thicker coatings can balance extra-sweet caramel.
- Premium chocolate adds richness without being waxy or overly sugary.
Texture: The Bite Factor
Caramel bars vary from chewy to melt-in-the-mouth.
- Ideal texture: a snap of chocolate, a flowing caramel centre, and a smooth chew.
- Too sticky: caramel that clings to teeth makes for a frustrating experience.
- Too runny: caramel that collapses creates mess instead of indulgence.
Overall Indulgence: The “One More Bite” Test
Beyond the technicals, a caramel bar must feel satisfying. We rated each on whether panelists reached for another bite — the ultimate measure of success.
