I used the M&S giant buttons (to fit the theme of being a M&S dupe cookie) but you can use any chocolate (doesn’t have to just be buttons). Some may not bake as well, like cadburys, due to the ingredients in the chocolate x

It’s anything inbetween – you use whatever weight

You can do either – I would just leave them to defrost naturally though if frozen once baked x

It’s the alternative notes in the ‘shortbread biscuits’ section about rubbing ingredients together with your hands to breadcrumbs.

I use slightly more towards room temp

For sure!

I personally don’t, the mixer broke them up for me, but you can!
