Ingredients

180 g Nomix gluten-free flour
20 g fine corn flour
70 g powdered sugar (incl. vanilla sugar)
45 g egg (smaller whole)
80 g butter
40 ml(g) milk
1 TSP instant coffee 
ca. 3 g baking powder 

For butter creme: béchamel sauce (mash) from 250 ml
milk and 30 g corn starch,100 g butter,
80 g powdered sugar flavoured with instant coffee and some rum

How to prepare

Let the instant coffee dissolve in milk. Knead the dough ingredients well and let stand in cold. Roll the dough flat (about 3 mm) and cut out the stars. Bake at 160 °C for about 12 minutes. 

Glue together using a mocha butter creme prepared in the following way. Beat the butter well with powdered sugar in approximately 1:1 ratio (less sugar if you want the creme less sweet). Rub some mash, (a thick, cooled pudding) made from milk and corn starch, into this substance. Add as much as you please to enjoy the creme. Fine-tune the taste by adding rum with the instant coffee dissolved in it.

And the third time mocha. You can smear the surface of the stars with icing made from some water with the instant coffee dissolved in it and powdered sugar. Beat until a nice smooth substance is achieved.
