I have made sugar cookies just on the weekend, I purchased initially from a fundraiser and the kids loved them. Here is the recipe

3 and 3/4 cups all purpose flour
1 1/2 cups white sugar
1 tsp vanilla extract
1/2 tsp salt
1/2 tsp Bicarb Soda
1 egg
1 cup butter at room temp (250gm)
1/2 cup whole fat greek yoghurt
1/2 tsp cinnamon (optional)

Cream butter and sugar until pale and fluffy.
Add egg, vanilla and yogurt and mix to combine.
Add in all dry ingredients and mix into a dough.
Wrap dough in the shape of a disc in glad wrap and refrigerate for 1hour.
Preheat oven to 180deg.
Roll out dough and cut out shapes. They keep better if they are cold and firm going into the oven. Bake 12mins and cool on the tray, they will harden on cooling and then you can completely cool on a wire rack and decorate.

I had so much dough I had to refrigerate inbetween batches. Kids loved them. These did not spread at all, they did rise a little.
