Method
Mix butter and sugar with a stand mixer or by hand. Add both flours and combine. Form a large ball and roll the dough out onto a lightly floured work surface, approx. 6 mm thick. Cut out small shapes and place on two baking sheets. Cover trays and chill for at least 30 minutes. Preheat the oven to 180°C, dust the cookies with powdered sugar and bake in the oven for 8-10 minutes until the edges are lightly golden. Remove from the oven and allow to cool for 5 minutes, loosen the biscuits with a knife and let cool completely on a wire rack. Spread ¼ teaspoon raspberry jam or samba or bionella on one heart and cover with a second heart. Also great for gifts!
