You will need 2 lightly greased baking sheets
1. Preheat the oven to gas mark 4/180C (160C in a fan oven). Add the low-fat spread to a food mixer then add the Canderel® Stevia and beat until pale and creamy then beat in the vanilla extract.
2. Add the egg yolk and buttermilk and a tbsp of flour then mix again until it is combined. Add the remaining flour and beat on slow until it comes together. Turn out onto a floured board and gather together to form a dough. Wrap in cling film and put in the fridge for 20 minutes to chill and firm.
3. Pull away pieces of dough about the size of a walnut and roll into balls then sit on the baking sheet and flatten with the heel of your hand.
4. Make a thumb indentation in each one and add a small amount of jam into this then put in the oven and bake for about 12-15 minutes or until golden. Remove and place on a wire rack and leave to cool.
