To prepare the bread, sift flour into the bowl of an electric mixer. Stir in milk powder, salt, sugar and yeast. Blend in butter using a pastry cutter. Add in egg and pour in water, essence and coffee liqueur. Attach the dough hook and beat for 30 minutes or until dough is smooth. Cover the dough with a damp tea towel. (To prevent a skin forming on the surface of the dough.) Leave aside to rise for 30 minutes or until doubled in size.
