Billionaire's Shortbread Recipe

We all know and love Millionaire’s shortbread but this takes it up to another level. The addition of a peanut butter fudge-like layer gives another texture and of course another flavour to the classic slice. I’ve always loved the blend of sweet and salty and so adding salted peanuts on the top was a no brainer. With nut butters being far more varied and easily available, you could totally swap out peanuts for something else, Pip & Nut’s Coconut Almond Butter is a particular favourite of mine- I just switch to toasted almonds on top and a sprinkle of sea salt!
