200g flour
170g sugar
100g butter (room temp)
If using unsalted butter 1/2tsp salt
1 egg
I mix it all in the kitchen aid, but you can do it by hand. Don’t over mix at any stage.
Mix together the butter and sugar, till just mixed.
Add the egg and mix a little more
Add the flour and mix until it just comes together as a dough (prob only 30 seconds). Careful, it will make a bit of a mess out of the kitchen aid ;)
The dough should be soft and workable but not over wet. If it is too wet and sticky you can add a little more flour.
Split in to 3 pieces (just because it’s easier to roll smaller pieces) and roll out to maybe 3mm thick. Use flour to stop it sticking. Cut an equal number of tops and bottoms. Bring together the scraps and reroll, keep rolling cutting until all the dough is done. Or if you want you can out some if the dough in the fridge wrapped in clingfilm or the like and roll and cook later. That way you get them warm and fresh again!
Cook at 180°C on baking paper for about 7mins until lightly browned.
Let cool a bit, sprinkle the tops with icing sugar and then stick together the tops and bottoms with jam.
