Mix the flour, ground almonds, cacao powder and salt. Add butter, xylitol, rice syrup and yeast.
Briefly knead the chopped chocolate or cacao nibs into the dough until they are evenly dispersed, then form a loaf and place it on a lined baking tray. Place in a plastic bag or cover with a tea towel and leave to rise for 1 and 1/2 hours, until doubled in size.
Allow to cool slightly, then brush with melted butter (or go full on treat with a glaze made with sugar free icing sugar* and coconut milk).
Serve warm or cold with butter or nut butter or jam (sugar free or regular).
*I make my own sugar free icing sugar by blitzing xylitol with a pinch of cornflour (cornstarch) in a coffee grinder until powdered
