Lightly grease a 900g loaf tin.
In a large bowl mix flours, milk powder, Xanthan Gum, yeast and 1.5g fine salt. Add butter, eggs and warm water.
Beat with a handheld electric whisk for 3min – thick batter will climb the whisk, but persevere!
Spoon dough into a prepared tin.
Use an oiled spatula to spread mixture evenly.
Cover tin loosley with oiled cling film (oiled side down) and leave to rise in a warm place for 1½hr – the centre of the dough will dome slightly.
Pre heat oven to 180°C ( 160°C Fan), gas mark 4.
Uncover dough and bake for 50-55min until golden.
Remove from tin and cool on a wire rack before serving.
To store keep in an airtight container at room temperature for up to 2 days.
