Chocolate sable
1 Beat the butter, sugar, flour and cocoa powder together in the mixer using the paddle attachment until a breadcrumb consistency has formed. Add the eggs and beat until incorporated. Split this into four equal measures โ this dough freezes well so it can be saved to make the dessert again and again.
2 Flatten out one batch andย wrap individually in cling film and chill. Roll out on to a tray lined with greaseproof paperย to the depth of a 50p piece. Bake in the oven at 170C/Gas Mark 3 for five minutes. Cut six circles with the circle cutter and place them back in the oven for a further five minutes. Cool then place into ready cling-filmed moulds.
