Mix margarine and xylitol in a bowl using a kitchen machine until you got a smooth mixture.
Add vanilla, maca, baking powder, cinnamon, salt & flour. Mix again using the kitchen machine until you got a mixture with a sand-alike texture.
Add plantbased milk spoon by spoon in case the dough is too dry and doesn`t stick together.
Wrap the dough in clingfilm and put in the fridge for one hour.
Preheat the oven at 180° celsius.
Sprinkle some flour on a flat surface and thinly roll out the dough. Add more flour in case it sticks to the surface. Cut out the Spitzbuben using a round cookie cutter. Cut out a star or heart or whatever shape you are using on half of the cut out cookies.
Place all of the cookies on a baking sheet layed out with parchment paper, put them in the oven and bake them for 7 up to 10 minutes. Take them out of the oven and let the cookies cool down.
Place a small amount of jam on the cookies without any cut out. These are going to be the bottom of your Spitzbuben cookies.
Dust the upper parts of the cookies with a little bit of confectioner`s sugar using a small sieve. Place the cookie with the cut out on top of the jam and slighlty press it on.
