Step 1

Preheat the oven to 200 degrees or 180 fan. Cream together the butter and sugars. Beat in the miso, vanilla extract and milk until the mixture is fully combined and lighter in colour.

Step 2

Add the flour and baking powder to the wet mix and bring together until a dough forms. Once the dough comes together, fold in the chocolate and crushed biscuits.

Step 3

Form the dough into 6-8 balls, press a square of chocolate into the top of the cookie dough ball then place them on two lined trays (leaving space between them as they will spread out as they cook) and bake for 12 minutes.

Step 4

Whilst they're still hot, re-shape if needed and sprinkle with flakey sea salt. Enjoy!
