For the gingerbread muffins, beat the egg. Mix the sugar, butter and milk well with the beaten egg.
Sift the baking powder, baking soda and gingerbread spice with the flour and carefully fold into the egg-sugar mixture. Immediately pour the batter into the muffin cups.
Bake the muffins for about 10-15 minutes in the Philips Airfryer hot air fryer.
Let the gingerbread muffins cool down and sprinkle with powdered sugar and cinnamon or decorate with chocolate icing, etc.
