Mix the flour, baking powder, spices, salt and brown sugar together. Stir in milk and honey.
If you like, you can add dates and nuts.
Put the batter in the cake pan and bake the ontbijtkoek for 90 minutes.
Remove the cake from the loaf pan immediately after baking and leave to cool on a wire rack.
Notes
Various ingredients such as small pieces of rock candy, nuts or dried fruits can be added as desired. The above mentionned optional ingredients resulted of my leftovers that had to go.
