Place the flour, yeast, xanthan gum and mixed spice into a large bowl, then add the sugar, dried fruit, clementine zest and almonds. Mix well
Add the coconut oil, eggs, vinegar and warm milk mixture
Mix the ingredients well until they come together into a sticky dough, getting your hands into the mixture and giving it a good squish!
Turn the dough onto a piece of clingfilm. Scatter the dough with gluten-free flour, cover with another piece of clingfilm and roll out into a rectangle measuring approx. 30cm by 25cm
Place the marzipan on another piece of clingfilm. Cover with clingfilm and roll into a rectangle shape measuring approx. 30cm by 12cm
Remove the clingfilm from the top of the dough and place the marzipan (minus clingfilm!) on one side of the dough around an inch from one long edge
Fold the dough over (using the clingfilm to help) and seal the edges with your fingers, sandwiching the marzipan in the middle of the dough
Place on a baking tray and cover with a damp T-towel
Place in the oven on its lowest temperature (around 40 or 50 degrees C) for 30 minutes
Once the dough has risen (it won't rise much) remove from the oven and turn the oven up to 180 degrees, 160 degree fan
Put the stollen back into the oven without the T-towel covering and bake for 25-30 minutes
Remove from the oven when golden and brush with melted coconut oil while still warm
Finally sprinkle generously with icing sugar and leave to cool before cutting into slices or bite sized pieces
