First of all TL, I hope you didn't really toss the biscuits out- they would have made a delicious base for cheesecake. Next time, toss them in the freezer until you can face turning them into something else.I have made star biscuits using this recipehttp://www.ukthermomix.com/recshow.php?rec_id=53I iced them with royal icing, and then stacked them to make a Christmas tree.Gingerbread does rise as it cooks, so you need to leave room for a little spreading when baking.If you are worried about the biscuits being too sweet after being iced, why don't you put the icing into a bag and then just drizzle it over the biscuit in a zig zag pattern. That way, they won't be overly sweet. Here are some photos of the biscuits I made with the linked recipe.
