Bourbon biscuits are the best! They are always the first to go when the biscuit tin is offered around, and I’ve finally mastered a way to make them myself. The glossy chocolate filling sandwiched between the crunchy biscuits is totally irresistible. Plus, you can choose whichever nut butter takes your fancy. I often reach for these as an afternoon treat and they’re perfect for sharing when friends and family come round for a cup of tea, too.
