OK, so it doesn't really taste like shortbread, the whole buttery thing still eludes me, but these are full of chocolate goodness and passed the taste test with a big thumbs up from the kids.
450gms Pam's compound choc chips OR Whitaker's dark chocolate
1 cup cornflour (GF would be rice flour)
2 cups flour (or a suitable GF baking mix)
10 Tbsps (scant 1/2 cup) rice or soy milk
Preheat oven to 150c
Either grease tray or line with baking paper.
Melt chocolate in a double boiler with milk, add sifted flour and cornflour and knead till combined and smooth (you may need an extra tablespoon of milk). Roll out to 1/2 inch thick, cut into shape and prick with a fork, or roll into balls and flatten with a fork. You need to work quickly with this dough as it solidifies as it cools down.
Bake 20 mins.
I originally had the time set to 30mins, but they turned out quite dry and hard the day after they were baked, and I think a shorter cooking time may improve the texture, we'll have to eat up the first batch so I can try them again (what a hardship for my two chocolate obsessed girls).
If the bikkies don't turn out soft enough then my next step will be to try a 1/2 tsp of cream of tarter.
