Biscuits for icing/sandwiching

This is the recipe I always turn to at Christmas to make our iced 'Christmas tree biscuits'. As it is relatively low in sugar, it can cope with any amount of icing or jam the children load onto it.
I substitute stevia for sugar too. Even with the icing, that makes it just a teaspoonful of sugar or less per biscuit depending on the size. (Using a pear or grape juice based conserve to sandwich them together instead of jam will also reduce the sugar levels, or use my sugar free butter cream recipe)

125g butter
60g sugar*
1/2tsp vanilla extract
220g plain flour**
1 egg, beaten
30g cornflour
1/2 tsp baking powder

royal icing for decorating, or butter-cream and/or jam to sandwich together

Preheat the oven to 180deg c. Butter several baking sheets.
Cream together the butter and sugar. Beat in the egg and vanilla extract.
Sieve flour, cornflour and baking powder together, and mix in with a spoon. Work into a soft dough using your hand.
Roll out on a floured board and cut into shapes.
Bake for 15 minutes. Remove from the baking sheets and cool on a wire cooling rack.
Once fully cold, they can be iced using royal icing, or sandwiched together with butter cream and/or jam.

*If you prefer, omit the sugar and replace with 60g xylitol, or 1/4tsp stevia powder.
**If you are eating a wheat-free diet, Spelt flour can be used as a replacement.

There is no limit to what you can do with these beauties. If you have a biscuit cutter collection to rival Nigella Lawson's, then you will have a heaps of inspiration, but here's a few more suggestions:

• Cut half with a circular cutter, and half with a ring cutter. Sandwich them together with one of the following:

                  Jam
                  chocolate ganache
                  icing flavoured with lemon or lime
                  vanilla, chocolate or orange butter-cream (especially good if you cover the top with chocolate!)

• Cut the dough into rectangles, cutting three holes in to half of them with a mini circular cutter. Fill with three different coloured jams to make traffic light biscuits for the kids.
• make a chocolate biscuit dough by sieving 30g of cocoa into the flour, and cover the baked biscuits with chocolate
• cut out mini circular biscuits. Once cold, dip into milk, dark or white chocolate using a chocolate dipper.
• Let the kids go wild with an assortment of cutters, icing and decorations
