I have a recipe for bourbon biscuits but the biscuit ended up too soft:
3oz flour 2.5 oz butter 1 oz sugar 1 egg yolk 1 tbsp cocoa
What could I do to make them crunchier like a real bourbon? I bake them at 180 for about 15 mins. I am happy to take someone's guaranteed crunchy biscuit recipe and amend so feel free to post yours! Thanks.
