Grate the marzipan with a grater, and whisk it together with the sugar and brown sugar using a hand mixer.
Add baking powder and wheat flour, and whisk until you have a uniform mass.
Add an egg white, whisk it into the mixture, and then do the same with the other egg white – if the filling is getting too runny, hold back some of the egg white.
Put the filling into a piping bag if you have one – otherwise leave it in the bowl.
Sprinkle each bread piece with a few drops of rose water, and pipe or spread the filling with a spoon to cover the bread.
Place the coffee breads on a baking sheet with parchment paper, and bake them at 200° fan oven for 10-12 minutes, or until they are nicely golden on top.
Let them cool a bit, but feel free to serve them warm.

Notes
#TIP‘Day-old’ should be taken with a grain of salt. Good sourdough breads often become beneficially ‘day-old’ only after several days.
