When it comes to British cakes, coffee and walnut is such a staple that if there isn’t one present at a bake sale or coffee morning, I’ll raise an eyebrow. I’ve taken the classic combination and put them in a cookie for something fun and quicker to make. Full of toasty walnuts and a hit of that very nostalgic instant coffee flavour, I finish them off with a white chocolate button as a nod to the sweet, creamy icing.
