Twix Secret Centre Biscuits – Chocolate-Covered Biscuits with Hidden Filling (UK)

Twix Secret Centre Biscuits take everything you love about Twix and flip it into biscuit form. These UK-exclusive treats feature crisp biscuits coated in smooth milk chocolate, with a surprise creamy chocolate center hidden inside.

They’re lighter than a standard chocolate bar but still deliver that signature Twix-style indulgence. Perfect with coffee, tea, or as a mid-day treat, these biscuits are a great option for anyone who loves discovering international chocolate snacks you won’t find in the U.S.
