Gingerbread (without ginger, feel free to add a teaspoon):

2 and 1/4 c. Self-raising flour

1 tsp cinnamon

1/2 tsp ground cloves

1/2 tsp nutmeg

90g butter

1/2 c. brown sugar

1/4 c. treacle (i.e. golden syrup)

1 egg

 

Icing:

1 egg white

1 and 1/2 c. icing sugar

 

This recipe comfortably makes 3 gingerbread houses that are 8cm wide, app. 9cm long, 9cm tall. The dimensions I use for my template are:

roof: 6cm by 9.5 cm

wall: 8cm by 5.25 cm

front: first draw a 9cm by 8cm rectangle, then measure to the 4cm point along the 8cm edge and make two 5.5 cm gables

I found that a packet of m&ms with some cut in half and some round lollies (chocolate freckles are good) work well, especially if you want to minimise your operation.
