Crisp, deeply chocolate, buttery, wholegrain, eggless, Wholegrain Chocolate Buckwheat Sablés are the yummiest cookies ever! Adapted from The Boy Who Bakes.
Place butter, brown sugar and vanilla in bowl of stand mixer with paddle attachment. Whisk on medium speed for 3-4 minutes until smooth.
Add the dry mix and ground chocolate, and mix on the lowest speed just enough for the dough to come together.{You can do this by hand to play safe}. Don't over-mix else the cookies will become hard.
Bring the dough together, either make a cylinder like roll, cling-wrap and chill for a couple of hours.
Alternatively, you could always use the dough for cut out cookies.
