Preheat oven to
180º C. Line a baking tray with a silicon sheet.
Sift together whole
wheat flour, all-purpose flour, baking powder and salt into a mixing bowl.
Add butter and rub
with your fingertips till the mixture resembles breadcrumbs.
Add powdered sugar
and mix well. Add 1 tbsp milk at a time and knead to form a stiff dough.
Roll out the dough on
a lightly floured worktop into a semi thick sheet. Keep a small round or any other shaped cookie cutter on the sheet and cut out cookies. Arrange them on the baking tray.
Keep the tray in the
preheated oven and bake them for 12 minutes.
Take the tray out of
the oven and set aside to cool.
Once they are cool
spread the jam on each cookie, sandwich two cookies together, dust icing sugar, keep them on a serving platter and serve.
