They look scrumptious Laura!

Biscuits don't mean the same thing in the UK as in the US so it is not surprising we don't have Grands in our shops.
In America, biscuits refer to small quick breads, which often use leavening like baking powder or baking soda. Biscuits are generally savoury (but can be sweet), and the texture should be tender and light. 2. In the British Isles, the term "biscuit" usually refers to a flat, thin cookie or cracker.
I'm not quite sure of what I could use instead.
